CopyValidity()

		ChannelMask	channels
	)

NotifyRefChanged()

RefResult NotifyRefChanged ( const Interval &  changeInt, RefTargetHandle  hTarget, PartID &  partID, RefMessage  message, BOOL  propagate  )

virtual

Receives and responds to messages.

A plugin which makes references must implement a method to receive and respond to messages broadcast by its dependents. This is done by implementing NotifyRefChanged(). The plugin developer usually implements this method as a switch statement where each case is one of the messages the plugin needs to respond to. The Method StdNotifyRefChanged calls this, which can change the partID to new value. If it doesn't depend on the particular message& partID, it should return REF_DONTCARE.

• For developer that need to update a dialog box with data about an object you reference note the following related to this method: This method may be called many times. For instance, say you have a dialog box that displays data about an object you reference. This method will get called many time during the drag operations on that object. If you updated the display every time you'd wind up with a lot of 'flicker' in the dialog box. Rather than updating the dialog box each time, you should just invalidate the window in response to the NotifyRefChanged() call. Then, as the user drags the mouse your window will still receive paint messages. If the scene is complex the user may have to pause (but not let up on the mouse) to allow the paint message to go through since they have a low priority. This is the way many windows in 3ds Max work.

Parameters

changeInt	- This is the interval of time over which the message is active. Currently, all plug-ins will receive FOREVER for this interval, with the exception of REFMSG_FLAGDEPENDENTS notifications. In that case, changeInt.Start() is the timepoint to perform the dependency test.
hTarget	- This is the handle of the reference target the message was sent by. The reference maker uses this handle to know specifically which reference target sent the message.
partID	- This contains information specific to the message passed in. Some messages don't use the partID at all. See the section List of Reference Messages for more information about the meaning of the partID for some common messages.
message	- The message parameters passed into this method is the specific message which needs to be handled.
propagate	- If called through ReferenceMaker::NotifyDependents(), the value of 'propagate' passed to it. Used if calling NotifyDependents() from within NotifyRefChanged().

Returns

The return value from this method is of type RefResult. This is usually REF_SUCCEED indicating the message was processed. Sometimes, the return value may be REF_STOP. This return value is used to stop the message from being propagated to the dependents of the item.

Implements ReferenceMaker.

Implements BaseObject.

Clone()

CoreExport RefTargetHandle Clone ( RemapDir &  remap )

virtual

This method is used by 3ds Max to clone an object.

See also

CloneRefHierarchy(), class RemapDir This method is called by 3ds Max to have the plugin clone itself. The plug-in's implementation of this method should copy both the data structure and all the data residing in the data structure of this reference target. The plugin should clone all its references as well. Also, the plug-in's implementation of this method must call BaseClone(). In order for classes derived from this class to clone cleanly, the Clone method should just create the new instance, and then call an implementation of BaseClone that clones the references and copies any other necessary data. For example:

class MyDerivedPlugin
    : public MyBasePlugin
{
    const int MY_REFERENCE = 1;
 
    ReferenceTarget* Clone(RemapDir& remap)
    {
        ReferenceTarget* result = new MyDerivedPlugin();
        BaseClone(this, result, remap);
        return result;
    }
 
    void BaseClone(ReferenceTarget* from, ReferenceTarget* to, RemapDir& remap)
    {
        if (!to || !from || from == to)
            return;    
        MyBasePlugin::BaseClone(from, to, remap);
        to->ReplaceReference(MY_REFERENCE, remap->CloneRef(from->GetReference(MY_REFERENCE)));
    }
};

This method should not be directly called by plug-ins. Instead, either RemapDir::CloneRef() or CloneRefHierachy() should be used to perform cloning. These methods ensure that the mapping from the original object to the clone is added to the RemapDir used for cloning, which may be used during backpatch operations

Note

See the remarks in method BaseClone() below.

Parameters

remap

- A RemapDir instance used for remapping references during a Clone.

Returns

A pointer to the cloned item.

Reimplemented from ReferenceTarget.

GetSubObjectLevel()

NumSubObjTypes()

CoreExport int NumSubObjTypes ( )

virtual

Objects and modifiers that support subobjects have to overwrite this method - as well as GetSubObjType() - and return a class derived from ISubObjType in GetSubObjType().

Developers can use the GenSubObjType for convenience. If the parameter passed into GetSubObjType is -1, the system requests a ISubObjType, for the current SubObjectLevel that flows up the modifier stack. If the subobject selection of the modifier or base object does not affect the subobj selection that flows up the stack, the method must return NULL. See meshsel.cpp for a sample implementation.

Returns

The number of sub-object types supported by the object or modifier.

Reimplemented from BaseObject.

GetSubObjType()

CoreExport ISubObjType * GetSubObjType ( int  i )

virtual

Returns a pointer to the sub-object type for the sub-object whose index is passed.

If the parameter i passed is -1 the system requests an ISubObjType for the current SubObjectLevel that flows up the modifier stack. If the subobject selection of the modifier or base object does not affect the sub-object selection that flows up the stack NULL must be returned. See the sample code in /MAXSDK/SAMPLES/MODIFIERS/MESHSEL.CPP.

Parameters

i	The zero based index of the sub-object type to get. See the remarks above.

Returns

The sub-object type. See Class ISubObjType.

Reimplemented from BaseObject.

virtual

This method returns the validity interval of the object as a whole at the specified time.

Parameters

t	The time to compute the validity interval.

Returns

The validity interval of the object, including that queried from the base class.

Reimplemented from Object.

GetExtendedProperties()

CoreExport BOOL GetExtendedProperties ( TimeValue  t, MSTR &  prop1Label, MSTR &  prop1Data, MSTR &  prop2Label, MSTR &  prop2Data  )

virtual

This method allows an object to return extended Properties fields.

It is called when the Object Properties dialog is being prepared. If you don't want to display any extended properties, simply return FALSE. To display extended property fields, place the field label in the appropriate label string and the display value in a formatted string. Two fields are supplied, each with a label and a data string; if only using one, make the second label field and data field blank (""). Return TRUE to indicate you have filled in the fields. The properties dialog will display your returned values.

Parameters

t	The time at which the strings are requested.
prop1Label	The string for the property 1 label.
prop1Data	The formatted data string to appear as property 1.
prop2Label	The string for the property 2 label.
prop2Data	The formatted data string to appear as property 2.

Returns

TRUE if this method is implemented and the fields are filled in; otherwise FALSE.

Reimplemented from Object.

PolygonCount()

CoreExport BOOL PolygonCount ( TimeValue  t, int &  numFaces, int &  numVerts  )

virtual

Retreives the number of faces and vertices of the polyginal mesh representation of this object.

If this method returns FALSE then this functionality is not supported. Note: Plug-In developers should use the global function GetPolygonCount(Object*, int&, int&) to retrieve the number f vertices and faces in an arbitrary object.

Parameters

t	The time at which to compute the number of faces and vertices.
numFaces	The number of faces is returned here.
numVerts	The number of vertices is returned here.

Returns

TRUE if the method is fully implemented; otherwise FALSE.

Reimplemented from Object.

ChannelValidity()

CoreExport Interval ChannelValidity ( TimeValue  t, int  nchan  )

virtual

Retrieve the current validity interval for the nchan channel of the object.

Note

Most procedural objects won't implement this method since they don't have individual channels. Developers wanting to get the validity interval for a procedural object should use Object::ObjectValidity() instead.

Parameters

t	The time to retrieve the validity interval of the channel.
nchan	Specifies the channel to return the validity interval of. See Object Channels.

Returns

The validity interval of the specified channel.

Reimplemented from Object.

SetChannelValidity()

CoreExport void SetChannelValidity ( int  nchan, Interval  v  )

virtual

nchan	Specifies the channel. See Object Channels.
v	The validity interval for the channel.

Reimplemented from Object.

InvalidateChannels()

CoreExport void InvalidateChannels ( ChannelMask  channels )

virtual

IsDeformable()

virtual int IsDeformable ( )

inlinevirtual

Indicates whether this object is deformable.

A deformable object is simply an object with points that can be modified. Deformable objects must implement the generic deformable object methods (NumPoints(), GetPoint(i), SetPoint(i), Deform()). A deformable object is simply an object with points that can be modified. These points can be stored in any form the object wants. They are accessed through a virtual array interface with methods to get and set the 'i-th' point. If an object has tangents for instance, it would convert them to and from points as necessary. For example, a simple Bezier spline object that stored its control handles relative to the knot would convert them to be absolute when GetPoint() was called with 'i' specifying one of the control points. When the control point is later set, the object can convert it back to be relative to its knot. At this point it could also apply any constraints that it may have, such as maintaining a degree of continuity. The idea is that the entity calling GetPoint(i) and SetPoint(i) doesn't care what the point represents. It will simply apply some function to the point.

Note

The Deformable object methods only need to be implemented if the object returns TRUE from this method.

Returns

Return nonzero if the object is deformable and implements the generic deformable object methods; otherwise 0.

Reimplemented from Object.

{ return 1; }  

NumPoints()

CoreExport int NumPoints ( )

virtual

The points of a deformable object are accessed through a virtual array interface.

This method specifies the number of points in the object. The meaning of 'points' is defined by the object. A TriObject uses the vertices as the points for example. b>

Returns

The number of points in the object.

Reimplemented from Object.

GetPoint()

CoreExport Point3 GetPoint ( int  i )

virtual

The points of a deformable object are accessed through a virtual array interface.

This method returns the 'i-th' point of the object.

Note

If your plug-in is a modifier and you want to operate on the selected points of the object you are modifying, you can't tell which points are selected unless you know the type of object. If it is a generic deformable object there is no way of knowing since the way the object handles selection is up to it. Therefore, if you want to operate on selected points of a generic deformable object, use a Deformer.

Parameters

i	Specifies which point should be returned.

Returns

The 'i-th' point of the object.

Reimplemented from Object.

SetPoint()

CoreExport void SetPoint ( int  i, const Point3 &  p  )

virtual

The points of a deformable object are accessed through a virtual array interface.

This method stores the 'i-th' point of the object.

p	The point to store.

Reimplemented from Object.

IsPointSelected()

PointsWereChanged()

CoreExport void PointsWereChanged ( )

virtual

Informs the object that its points have been deformed, so it can invalidate its cache.

A developer who uses the GetPoint() / SetPoint() approach to modifying an object will call PointsWereChanged() to invalidate the object's cache. For example, if a modifier calls SetPoint(), when it is finished it should call this method so the object can invalidate and/or update its bounding box and any other data it might cache.

Reimplemented from Object.

GetDeformBBox()

CoreExport void GetDeformBBox ( TimeValue  t, Box3 &  box, Matrix3 *  tm = NULL, BOOL  useSel = FALSE  )

virtual

This method computes the bounding box in the objects local coordinates or the optional space defined by tm.

Note: If you are looking for a precise bounding box, use this method and pass in the node's object TM (INode::GetObjectTM()) as the matrix.

Parameters

t	The time to compute the box.
box	A reference to a box the result is stored in.
tm	This is an alternate coordinate system used to compute the box. If the tm is not NULL this matrix should be used in the computation of the result.
useSel	If TRUE, the bounding box of selected sub-elements should be computed; otherwise the entire object should be used.

Reimplemented from Object.

Deform()

CoreExport void Deform ( Deformer *  defProc, int  useSel  )

virtual

This is the method used to deform the object with a deformer.

The developer should loop through the object's points calling the defProc for each point (or each selected point if useSel is nonzero). The Deform() method is mostly a convenience. Modifiers can implement a 'Deformer' callback object which is passed to the Deform() method. The object then iterates through its points calling their deformer's callback for each point. The only difference between using the Deform() method as opposed to iterating through the points is that the Deform() method should respect sub-object selection. For example, the TriObject's implementation of Deform() iterates through its vertices, if the TriObject's selection level is set to vertex then it only calls the Deformer's callback for vertices that are selected. This way modifiers can be written that can be applied only to selection sets without any specific code to check selected points. The default implementation of this method just iterates through all points using GetPoint(i) and SetPoint(i). If an object supports sub-object selection sets then it should override this method.

Parameters

defProc	A pointer to an instance of the Deformer class. This is the callback object that actually performs the deformation.
useSel	A flag to indicate if the object should use the selected points only. If nonzero the selected points are used; otherwise all the points of the object are used.

Default Implementation:

void Object::Deform(Deformer *defProc,int useSel)
{
    int nv = NumPoints();
    for (int i=0; i<nv; i++)
        SetPoint(i,defProc->Map(i,GetPoint(i)));
    PointsWereChanged();
}

Sample Code:

This code shows the TriObject implementation of this method. Note how it looks at the useSel parameter to only call the selected points if required.

void TriObject::Deform(Deformer *defProc,int useSel)
{
    int nv = NumPoints();
    int i;
    if ( useSel ) {
        BitArray sel = mesh.VertexTempSel();
        float *vssel = mesh.getVSelectionWeights ();
        if (vssel) {
            for (i=0; i<nv; i++) {
                if(sel[i]) {
                    SetPoint(i,defProc->Map(i,GetPoint(i)));
                    continue;
                }
                if (vssel[i]==0) continue;
                Point3 & A = GetPoint(i);
                Point3 dir = defProc->Map(i,A) - A;
                SetPoint(i,A+vssel[i]*dir);
            }
        }
        else {
            for (i=0; i<nv; i++) if (sel[i])
                SetPoint(i,defProc->Map(i,GetPoint(i)));
        }
    }
    else {
        for (i=0; i<nv; i++)
            SetPoint(i,defProc->Map(i,GetPoint(i)));
    }
    PointsWereChanged();

IsParamSurface()

virtual BOOL IsParamSurface ( )

inlinevirtual

There are several methods used to access a parametric position on the surface of the object.

If this method returns TRUE then Object::GetSurfacePoint() will be called to return a point on the surface that corresponds to the u and v parameters passed to it. If this method returns FALSE then it is assumed the object does not support returning a point on the surface based on parameteric values. For sample code see /MAXSDK/SAMPLES/OBJECTS/SPHERE.CPP. If the object has several parametric surfaces then a second version of GetSurfacePoint() with an integer which specifies which surface will be called.

Reimplemented from Object.

{return TRUE;}

GetSurfacePoint()

CoreExport Point3 GetSurfacePoint ( TimeValue  t, float  u, float  v, Interval &  iv  )

virtual

This method needs to be implemented if Object::IsParamSurface() returns TRUE.

This method is used to retrieve a point on the surface of the object based on two parameters of the surface, u and v. Note: This method assumes there is a single parametric surface. If there is more than 1 (NumSurfaces() returns > 1, use the GetSurface() method below which allows for multiple surfaces.

Parameters

t	The time to retrieve the point.
u	The parameter along the horizontal axis of the surface.
v	The parameter along the vertical axis of the surface.
iv	This interval is updated based on the interval of the surface parameter.

Reimplemented from Object.

IsMappable()

virtual int IsMappable ( )

inlinevirtual

This method lets you know if the ApplyUVWMap() method is available for this object.

This is used by things like the UVW mapping modifier, so that it can determine which objects can have their mapping modified. Returns nonzero if the object is mappable; otherwise zero.

Reimplemented from Object.

{ return 1; }

NumMapChannels()

virtual int NumMapChannels ( )

inlinevirtual

Returns the maximum number of channels supported by this type of object.

TriObjects for instance return MAX_MESHMAPS which is currently set to 100.

Reimplemented from Object.

{ return patch.NumMapChannels (); }

NumMapsUsed()

virtual int NumMapsUsed ( )

inlinevirtual

Returns the number of maps currently used by this object.

This is at least 1+(highest channel in use). This is used so a plug-in that does something to all map channels doesn't always have to do it to every channel up to MAX_MESHMAPS but rather only to this value.

Reimplemented from Object.

{ return patch.getNumMaps(); }

ApplyUVWMap()

virtual void ApplyUVWMap ( int  type, float  utile, float  vtile, float  wtile, int  uflip, int  vflip, int  wflip, int  cap, const Matrix3 &  tm, int  channel = 1  )

inlinevirtual

This method may be called to map the object with UVW mapping coordinates.

If the object returns nonzero from IsMappable() then this method should be implemented.

Parameters

type	The mapping type. One of the following values: MAP_PLANAR MAP_CYLINDRICAL MAP_SPHERICAL MAP_BALL MAP_BOX
utile	Number of tiles in the U direction.
vtile	Number of tiles in the V direction.
wtile	Number of tiles in the W direction.
uflip	If nonzero the U values are mirrored.
vflip	If nonzero the V values are mirrored.
wflip	If nonzero the W values are mirrored.
cap	This is used with MAP_CYLINDRICAL. If nonzero, then any face normal that is pointing more vertically than horizontally will be mapped using planar coordinates.
tm	This defines the mapping space. As each point is mapped, it is multiplied by this matrix, and then it is mapped.
channel	This indicates which channel the mapping is applied to. See Mapping Channels .

Reimplemented from Object.

                                                                                      {
                patch.ApplyUVWMap(type,utile,vtile,wtile,uflip,vflip,wflip,cap,tm,channel); }

CanConvertToType()

CoreExport int CanConvertToType ( Class_ID  obtype )

virtual

Indicates whether the object can be converted to the specified type.

If the object returns nonzero to indicate it can be converted to the specified type, it must handle converting to and returning an object of that type from ConvertToType(). Note that all overrides of this method should either call _super::CanConvertToType or test to see if obtype == anyObjectClassID. If true, the method should return true.

See also

Class ObjectConverter for additional details on converting objects between types.

Parameters

obtype

The Class_ID of the type of object to convert to. See Class Class_ID, Class IDs defined in plugapi.h.

Returns

Nonzero if the object can be converted to the specified type; otherwise 0.

Reimplemented from Object.

ConvertToType()

CoreExport Object * ConvertToType ( TimeValue  t, Class_ID  obtype  )

virtual

This method converts this object to the type specified and returns a pointer it.

Note that if ConvertToType() returns a new object it should be a completely different object with no ties (pointers or references) to the original. Note that all overrides of this method should either call _super::ConvertToType or test to see if obtype == anyObjectClassID. If true, the object should return itself.

The following is an issue that developers of world space modifiers need to

be aware of if the world space modifier specifies anything but generic deformable objects as its input type. In other words, if a world space modifier, in its implementation of Modifier::InputType(), doesn't specifically return defObjectClassID then the following issue regarding the 3ds Max pipeline needs to be considered. Developers of other plug-ins that don't meet this condition don't need to be concerned with this issue.

World space modifiers that work on anything other than generic deformable

objects are responsible for transforming the points of the object they modify into world space using the ObjectState TM. To understand why this is necessary, consider how 3ds Max applies the node transformation to the object flowing down the pipeline.

In the geometry pipeline architecture, the node in the scene has its

transformation applied to the object in the pipeline at the transition between the last object space modifier and the first world space modifier. The node transformation is what places the object in the scene – thus this is what puts the object in world space. The system does this by transforming the points of the object in the pipeline by the node transformation. This is only possible however for deformable objects. Deformable objects are those that support the Object::IsDeformable(), NumPoints(), GetPoint() and SetPoint() methods. These deformable objects can be deformed by the system using these methods, and thus the system can modify the points to put them in world space itself.

If a world space modifier does not specify that it works on deformable

objects, the system is unable to transform the points of the object into world space. What it does instead is apply the transformation to the ObjectState TM. In this case, a world space modifier is responsible for transforming the points of the object into world space itself, and then setting the ObjectState TM to the identity. There is an example of this in the sample code for the Bomb space warp. The Bomb operates on TriObjects and implements InputType() as { return Class_ID(TRIOBJ_CLASS_ID,0); }. Since it doesn't specifically return defObjectClassID, it is thus responsible for transforming the points of the object into world space itself. It does this in its implementation of ModifyObject() as follows:

if (os->GetTM())
{
    Matrix3 tm = *(os->GetTM());
    for (int i=0; i<triOb->mesh.getNumVerts(); i++) {
        triOb->mesh.verts[i] = triOb->mesh.verts[i] *tm;
    }
    os->obj->UpdateValidity(GEOM_CHAN_NUM,os->tmValid());
    os->SetTM(NULL,FOREVER);
}

As the code above shows, the Bomb checks if the ObjectState TM is non-NULL. If it is, the points of the object are still not in world space and thus must be transformed. It does this by looping through the points of the TriObject and multiplying each point by the ObjectState TM. When it is done, it sets the ObjectState TM to NULL to indicate the points are now in world space. This ensure that any later WSMs will not transform the points with this matrix again.

For the Bomb world space modifier this is not a problem since it specifies

in its implementation of ChannelsChanged() that it will operate on the geometry channel (GEOM_CHANNEL). Certain world space modifiers may not normally specify GEOM_CHANNEL in their implementation of ChannelsChanged(). Consider the camera mapping world space modifier. Its function is to apply mapping coordinates to the object it is applied to. Thus it would normally only specify TEXMAP_CHANNEL for ChannelsChanged(). However, since it operates directly on TriObjects, just like the Bomb, the system cannot transform the points into world space, and therefore the camera mapping modifier must do so in its implementation of ModifyObject(). But since it is actually altering the points of the object by putting them into world space it is altering the geometry channel. Therefore, it should really specify GEOM_CHANNEL | TEXMAP_CHANNEL in its implementation of ChannelsChanged(). If it didn't do this, but went ahead and modified the points of the object anyway, it would be transforming not copies of the points, but the original points stored back in an earlier cache or even the base object.

This is the issue developers need to be aware of. To state this in simple

terms then: Any world space modifier that needs to put the points of the object into world space (since it doesn't implement InputType() as defObjectClassID) needs to specify GEOM_CHANNEL in its implementation of ChannelsChanged().

Parameters

t	The time at which to convert.
obtype	The Class_ID of the type of object to convert to. See Class Class_ID, Class IDs defined in plugapi.h.

Returns

A pointer to an object of type obtype.

Default Implementation:

{ return NULL; }

Sample Code:

The following code shows how a TriObject can be retrieved from a node. Note on the code that if you call ConvertToType() on an object and it returns a pointer other than itself, you are responsible for deleting that object.

// Retrieve the TriObject from the node
int deleteIt;
TriObject *triObject = GetTriObjectFromNode(ip->GetSelNode(0),deleteIt);
// Use the TriObject if available
if (!triObject) return;
// ...
// Delete it when done...
if (deleteIt) triObject->DeleteMe();
 
// Return a pointer to a TriObject given an INode or return NULL
// if the node cannot be converted to a TriObject
TriObject *Utility::GetTriObjectFromNode(INode *node, int &deleteIt)
{
    deleteIt = FALSE;
    Object *obj = node->EvalWorldState(0).obj;
    if (obj->CanConvertToType(Class_ID(TRIOBJ_CLASS_ID, 0))) {
        TriObject *tri = (TriObject *) obj->ConvertToType(0,Class_ID(TRIOBJ_CLASS_ID, 0));
// Note that the TriObject should only be deleted
// if the pointer to it is not equal to the object
// pointer that called ConvertToType()
        if (obj != tri) 
            deleteIt = TRUE;
        return tri;
    }
    else {
        return NULL;
    }
}

GetCollapseTypes()

CoreExport void GetCollapseTypes ( Tab< Class_ID > &  clist, Tab< MSTR * > &  nlist  )

virtual

When the user clicks on the Edit Stack button in the modify branch a list of 'Convert To:' types is presented.

The use may click on one of these choices to collapse the object into one of these types (for instance, an Editable Mesh or an Editable NURBS object). This method returns a list of Class_IDs and descriptive strings that specify the allowable types of objects that this object may be collapsed into. Note: Most plug-ins call the base class method in Object in their implementation of this method. The base class implementation provided by Object checks if the object can convert to both an editable mesh and an editable spline. If it can, these are added to the allowable types.

Parameters

clist	The table of allowable Class_IDs.
nlist	The table of pointers to strings that correspond to the table of Class_IDs above.

Sample Code:

void SphereObject::GetCollapseTypes(Tab<Class_ID> &clist,Tab<MSTR*>&nlist)
{
    Object::GetCollapseTypes(clist, nlist);
    Class_ID id = EDITABLE_SURF_CLASS_ID;
    MSTR *name = new MSTR(GetString(IDS_SM_NURBS_SURFACE));
    clist.Append(1,&id);
    nlist.Append(1,&name);
}

FreeChannels()

CoreExport void FreeChannels ( ChannelMask  channels )

virtual

This method deletes the memory associated with the specified channels and set the intervals associated with the channels to invalid (empty).

Parameters

channels

Specifies the channels to free.

Reimplemented from Object.

MakeShallowCopy()

CoreExport Object * MakeShallowCopy ( ChannelMask  channels )

virtual

This method must make a copy of its "shell" and then shallow copy (see below) only the specified channels.

It must also copy the validity intervals of the copied channels, and invalidate the other intervals.

Parameters

channels

The channels to copy.

Returns

A pointer to the shallow copy of the object.

Reimplemented from Object.

ShallowCopy()

CoreExport void ShallowCopy ( Object *  fromOb, ChannelMask  channels  )

virtual

This method copies the specified channels from the fromOb to this and copies the validity intervals.

A plug-in needs to copy the specified channels from the specified object fromOb to itself by just copying pointers (not actually copying the data). No new memory is typically allocated, this method is just copying the pointers.

Parameters

fromOb	Object to copy the channels from.
channels	Channels to copy.

Reimplemented from Object.

NewAndCopyChannels()

CoreExport void NewAndCopyChannels ( ChannelMask  channels )

virtual

This method replaces the locked channels with newly allocated copies.

It will only be called if the channel is locked.

Parameters

channels

The channels to be allocate and copy.

Reimplemented from Object.

GetSubselState()

CoreExport DWORD GetSubselState ( )

virtual

For objects that have sub selection levels, this method returns the current selection level of the object.

For example, a TriObject has the following selection levels: object, vertex, face, edge. Other object types may have different selection levels. The only standard is that a value of 0 indicates object level. b>

Returns

The current selection level of the object.

Reimplemented from Object.

IntersectRay()

CoreExport int IntersectRay ( TimeValue  t, Ray &  r, float &  at, Point3 &  norm  )

virtual

This method is called to compute the intersection point and surface normal at this intersection point of the ray passed and the object.

Parameters

t	The time to compute the intersection.
r	Ray to intersect. See Class Ray.
at	The point of intersection.
norm	Surface normal at the point of intersection.

Returns

Nonzero if a point of intersection was found; otherwise 0.

GetWorldBoundBox() [2/2]

CoreExport void GetWorldBoundBox ( TimeValue  t, INode *  inode, ViewExp *  vp, Box3 &  box  )

virtual

This method returns the world space bounding box for Objects (see below for the Sub-object gizmo or Modifiers gizmo version).

The bounding box returned by this method does not need to be precise. It should however be calculated rapidly. The object can handle this by transforming the 8 points of its local bounding box into world space and take the minimums and maximums of the result. Although this isn't necessarily the tightest bounding box of the objects points in world space, it is close enough.

Parameters

t	The time to compute the bounding box.
inode	The node to calculate the bounding box for.
vp	An interface pointer that can be used to call methods associated with the viewports.
box	Contains the returned bounding box.

Reimplemented from BaseObject.

GetLocalBoundBox()

CoreExport void GetLocalBoundBox ( TimeValue  t, INode *  inode, ViewExp *  vp, Box3 &  box  )

virtual

This is the object space bounding box, the box in the object's local coordinates.

The system expects that requesting the object space bounding box will be fast.

Parameters

t	The time to retrieve the bounding box.
inode	The node to calculate the bounding box for.
vp	An interface pointer that may be used to call methods associated with the viewports.
box	Contains the returned bounding box.

Reimplemented from BaseObject.

IsInstanceDependent()

CoreExport int IsInstanceDependent ( )

virtual

If an object creates different meshes depending on the particular instance (view-dependent) it should return nonzero; otherwise 0.

Reimplemented from GeomObject.

GetRenderMesh()

CoreExport Mesh * GetRenderMesh ( TimeValue  t, INode *  inode, View &  view, BOOL &  needDelete  )

virtual

This method should be implemented by all renderable GeomObjects.

It provides a mesh representation of the object for use by the renderer. Primitives that already have a mesh cached can just return a pointer to it (and set needDelete to FALSE). Implementations of this method which take a long time should periodically call View::CheckForRenderAbort() to see if the user has canceled the render. If canceled, the function can either return NULL, or return a non null pointer with the appropriate value for needDelete. (If needDelete is TRUE a non-null mesh will be deleted.)

Parameters

t	The time to get the mesh.
inode	The node in the scene.
view	If the renderer calls this method it will pass the view information here. See Class View.
needDelete	Set to TRUE if the renderer should delete the mesh, FALSE otherwise.

Returns

A pointer to the mesh object.

DeleteThis()

virtual CoreExport void DeleteThis ( )

virtual

Deletes an instance of this class.

3ds Max calls this method when it needs to delete a plugin object (an instance of a class derived from Animatable). Similarly, plugins that need to delete instances of an Animatable or a class directly derived from it via an Animatable pointer, should call this method instead of calling directly operator delete. Following these rules will ensure that the same memory manager is used to allocate and deallocate the object. The default implementation of this method deletes the object. Plugin instances that never need to be deleted from the heap can overwrite this method to do nothing.

Note

See the method ClassDesc::Create() for details on how Max allocates plugin objects.

See ReferenceMaker::DeleteMe() and ReferenceTarget::MaybeAutoDelete() for information on how plugin instances are deleted by the system.

Remarks

FreeCaches()

virtual void FreeCaches ( )

inlinevirtual

Remarks

This is called to delete any item that can be rebuilt. For example, the procedural sphere object has a mesh that it caches. It could call Mesh::FreeAll() on the mesh from this method. This will free the vertex/face/uv arrays. If the sphere is ever evaluated again it can just rebuild the mesh. If an object (like a sphere) has modifiers applied to it, and those modifiers are not animated, then the result of the pipeline is cached in the node. So there is no reason for the sphere to also have a cache of its representation. Therefore when this method is called, the sphere can free the data of the mesh.

Default Implementation:

{}

Reimplemented from Animatable.

{patch.InvalidateGeomCache(); }

ClassID()

virtual Class_ID ClassID ( )

inlinevirtual

Retrieves a constant that uniquely identifies the plugin class.

This method must return the unique ID for the plugin class. If two ClassIDs conflict, the system will only load the first conflicting one it finds. A program (gencid.exe) is provided to generate unique class id values.

Returns

A class id that uniquely identifies a plugin class

See also

Reimplemented from Animatable.

{ return Class_ID(PATCHOBJ_CLASS_ID,0); }

IsSubClassOf()

CoreExport BOOL IsSubClassOf ( Class_ID  classID )

virtual

returns true if the animatable has sub-classed off the given class

If an object is a sub-class of a particular class, it will have a different ClassID() because it is a different class. This method allows an object to indicate that it is a sub-class of a particular class and therefore can be treated as one. For example, a class could be derived from TriObject. This derived class would have a different ClassID() then the TriObject's class ID however it still can be treated (cast) as a TriObject because it is derived from TriObject. Note the default implelementation: a class is considered to also be a subclass of itself.

Parameters

classID

The Class_ID of the item that this class is a sub-class of.

Returns

TRUE if this class is a sub-class of classID; otherwise FALSE.

Default Implementation:

{return classID==ClassID();}

Reimplemented from Animatable.

GetClassName()

virtual CoreExport void GetClassName ( MSTR &  s, bool  localized = true  ) const

overridevirtual

Retrieves the name of the plugin class.

This name is used in 3ds Max's UI and in MAXScript. For Material plug-ins this method is used to put up the material "type" name in the Material Editor.

Parameters

s	Reference to a string filled in with the name of the plugin class.
localized	If true, then the class name returned should be localized in the language 3ds Max is currently using. Otherwise it should be the class name in English. If a plugin does not provide localized string resources, it can disregard this parameter and always return the class name in English.

Reimplemented from Animatable.

GetInterface()

CoreExport void * GetInterface ( ULONG  id )

virtual

Remarks

This method provides a mechanism for extending the class in the future. In 3ds Max 4.0 there are new interfaces that are accessed by passing an id to this method and it will respond by returning the corresponding interface pointer.

This method has been used however for a different purpose. It currently is used to determine if an object is of a particular class. With controllers for example, there is one base class Control, however there are many super classes (CTRL_FLOAT_CLASS_ID, CTRL_SCALE_CLASS_ID, etc.). If you wanted to find out if a given Animatable was a controller you would need to compare its SuperClassID to all the known types and only if it wasn't one of the known types could you be sure it wasn't a controller. Having to do this is inconvenient for a developer.

Instead the Control class implements this method. It looks at the id, and if it matches a predefined constant I_CONTROL, it returns its this pointer. In this way, given any Animatable, it is easy to find out if it is a controller by simply asking for the control interface. There is a macro that does this:

#define GetControlInterface(anim)
((Control*)anim-\>GetInterface(I_CONTROL))

A plug-in developer may use this macro as follows:

Control *c = GetControlInterface(anim);

This will either be NULL or a pointer to a valid controller.

Note: Plug-in defined interfaces should be greater than the following value:

#define I_USERINTERFACE 0x0000ffff

If a plug-in implements this method for its own purposes, it would, in general, switch on the id and if it is not aware of the id it would call this method on the base class. Otherwise it could respond to the id as it needed. See the sample code below for the how the Control class implements this method.

Parameters

id	The id of the interface.

Default Implementation:

{ return NULL; }

Sample Code:

The following is the Control class implementation of this method. It looks at the id passed, and if it matches I_CONTROL it returns its this pointer. Otherwise it calls the base class method.

void* Control::GetInterface(ULONG id)
{
    if (id==I_CONTROL) {
        return this;
    }
    else {
        return Animatable::GetInterface(id);
    }
}

Reimplemented from Object.

GetObjectName()

virtual CoreExport const MCHAR * GetObjectName ( bool  localized = true ) const

overridevirtual

Returns

the name that will appear in the modifier stack.

Parameters

localized

If true, then the object name returned should be localized in the language 3ds Max is currently using. Otherwise it should be the object name in English. If a plugin does not provide localized string resources, it can disregard this parameter and always return the object name in English.

Reimplemented from BaseObject.

NumSubs()

int NumSubs ( )

inlinevirtual

Remarks

The system uses a virtual array mechanism to access the sub-anims of a plug-in. This method returns the total number of sub-anims maintained by the plug-in. If a plug-in is using a parameter block to manage its parameters it should just return 1 for all the parameters directed by the parameter block.

Returns

The number of sub-anims used by the plug-in.

Default Implementation:

{ return 0; }

Reimplemented from Animatable.

{ return 1; }   // Just tell it about the Point Controller Container

SubAnim()

CoreExport Animatable * SubAnim ( int  i )

virtual

Remarks

This method returns a pointer to the 'i-th' sub-anim. If a plug-in is using a parameter block to manage all its parameters it should just return a pointer to the parameter block itself from this method. This method may return NULL so developers need to check the return value before calling other sub anim methods (such as SubAnimName()).

Parameters

i	This is the index of the sub-anim to return.

Default Implementation:

{ return NULL };

Reimplemented from Animatable.

SubAnimName()

CoreExport MSTR SubAnimName ( int  i, bool  localized = true  )

overridevirtual

Remarks

This method returns the name of the 'i-th' sub-anim to appear in track view. The system has no idea what name to assign to the sub-anim (it only knows it by the virtual array index), so this method is called to retrieve the name to display. Developer need to make sure the 'i-th' SubAnim() is non-NULL or this method will fail.

Parameters

i	The index of the parameter name to return
localized	If true, then the sub-anim name returned should be localized in the language 3ds Max is currently using. Otherwise it should be the sub-anim name in English. If a plugin does not provide localized string resources, it can disregard this parameter and always return the sub-anim name in English.

Returns

The name of the 'i-th' parameter.

Reimplemented from Animatable.

AssignController()

CoreExport BOOL AssignController ( Animatable *  control, int  subAnim  )

virtual

Remarks

This method is called to assign the controller to the sub-anim whose index is passed.

Parameters

control	The controller to assign.
subAnim	The index of the sub-anim to assign the controller to.

Default Implementation:

{ return FALSE; }

Returns

Returns TRUE if the controller was assigned; otherwise FALSE.

Reimplemented from Animatable.

SubNumToRefNum()

int SubNumToRefNum ( int  subNum )

inlinevirtual

Remarks

This method is used for copying and pasting in the track view. It converts an anim index to a reference index or returns -1 if there is no correspondence. If a client does not wish an anim to be copied or pasted then it can return -1 even if there is a corresponding reference num.

Parameters

subNum

The anim index to return the corresponding reference index of.

Default Implementation:

{ return -1}

Returns

The reference index corresponding to the anim index passed. Return -1 if there is no correspondence.

Reimplemented from Animatable.

{return subNum;}

SelectSubAnim()

CoreExport BOOL SelectSubAnim ( int  subNum )

virtual

Remarks

This method is available in release 2.0 and later only.

When a user is in Track View in Edit Keys mode and clicks on the green triangle of a controller then this method will be called on the client with the appropriate sub number that corresponds to it. For instance, the Editable Mesh object implements this to allow the user to select vertices that are animated from the Track View.

Parameters

subNum

The index of the sub-anim that was clicked on.

Returns

TRUE if implemented; otherwise FALSE. (Track View will call RedrawViewports() if something returns TRUE from this method).

Default Implementation:

{return FALSE;}

Reimplemented from Animatable.

HasControllers()

RescaleWorldUnits()

CoreExport void RescaleWorldUnits ( float  f )

virtual

Rescale size of all world units in reference hierarchy.

This method is available in release 2.0 and later only. Must call ClearAFlagInHierarchy(rm, A_WORK1) or ClearAFlagInAllAnimatables(A_WORK1) before doing this on a reference hierarchy. This may be implemented to rescale the size of all world units in a reference hierarchy. Developers must call

if (TestAFlag(A_WORK1))
    return;
SetAFlag(A_WORK1);

before doing this on a reference hierarchy.

Parameters

f	- The scale factor.

Reimplemented from ReferenceMaker.

NumRefs()

int NumRefs ( )

inlinevirtual

Returns the total number of references this ReferenceMaker can hold.

The plugin implements this method to indicate the total number of of references it can make. This includes all references whether they are NULL (inactive) or non-NULL (active) at the time when this method is called. A plugin can hold a variable number of references, thus the return value of this method is not to be cached and reused by client code.

Returns

The total number of references this plugin can hold. The default implementation is return 0.

Reimplemented from ReferenceMaker.

{return vertCont.Count() + vecCont.Count() + 1;}    // vert conts + vec conts + Point Controller Container

GetReference()

CoreExport RefTargetHandle GetReference ( int  i )

virtual

Returns the 'i-th' reference.

The plugin implements this method to return its 'i-th' reference. The plug-in simply keeps track of its references using an integer index for each one. This method is normally called by the system.

Parameters

i	- The index of the reference to retrieve. Valid values are from 0 to NumRefs()-1.

Returns

The reference handle of the 'i-th' reference. Note that different calls to this method with the same 'i' value can result in different reference handles being retrieved, as the plugin changes the scene objects it references as its 'i-th' reference.

Reimplemented from ReferenceMaker.

SetReference()

virtual CoreExport void SetReference ( int  i, RefTargetHandle  rtarg  )

protectedvirtual

Stores a ReferenceTarget as its 'i-th' reference`.

The plugin implements this method to store the reference handle passed to it as its 'i-th' reference. In its implementation of this method, the plugin should simply assign the reference handle passed in as a parameter to the member variable that holds the 'i-th' reference. Other reference handling methods such as ReferenceMaker::DeleteReference(), or ReferenceMaker::ReplaceReference() should not be called from within this method. The plugin itself or other plugins should not call this method directly. The system will call this method when a new reference is created or an existing one is replaced by calling ReferenceMaker::ReplaceReference().

Parameters

i	- The index of the reference to store. Valid values are from 0 to NumRefs()-1.
rtarg	- The reference handle to store.

Reimplemented from ReferenceMaker.

RemapRefOnLoad()

CoreExport int RemapRefOnLoad ( int  iref )

virtual

Used to load old files with references.

Implement this if you have added or deleted references and are loading an old file that needs to have its references remapped.
This method is used when you have modified a ReferenceMaker to add or delete references, and are loading old files. It gets called during the reference mapping process, after the Load() method is called. You determine what version is loading in the Load(), and store the version in a variable which you can look at in RemapRefOnLoad() to determine how to remap references. The default implementation of this method just returns the same value it is passed, so you don't need to implement it unless you have added or deleted references from your class. This method makes it a lot easier to load old files when the reference topology has changed.

Parameters

iref	- The input index of the reference.

Returns

The output index of the reference.

BeginEditParams()

virtual CoreExport void BeginEditParams ( IObjParam *  ip, ULONG  flags, Animatable *  prev  )

virtual

Remarks

This method is called by the system when the user may edit the item's (object, modifier, controller, etc.) parameters.

Parameters

ip	Interface pointer. The developer can use it to call methods such as AddRollupPage(). Note that this pointer is only valid between BeginEditParams() and EndEditParams(). It should not be used outside this interval.
flags	Describe which branch of the command panel or dialog the item is being edited in. The following are possible values: BEGIN_EDIT_CREATE Indicates an item is being edited in the create branch. BEGIN_EDIT_MOTION Indicates a controller is being edited in the motion branch. BEGIN_EDIT_HIERARCHY Indicates a controller is being edited in the Pivot subtask of the hierarchy branch. BEGIN_EDIT_IK Indicates a controller is being edited in the IK subtask of the hierarchy branch. BEGIN_EDIT_LINKINFO Indicates a controller is being edited in the Link Info subtask of the hierarchy branch.
prev	Pointer to an Animatable object. This parameter may be used in the motion and hierarchy branches of the command panel. This pointer allows a plug-in to look at the ClassID of the previous item that was being edited, and if it is the same as this item, to not replace the entire UI in the command panel, but simply update the values displayed in the UI fields. This prevents the UI from 'flickering' when the current item begins its edit. For example, if you are in the motion branch and are looking at an item's PRS controller values, and then select another item that is displayed with a PRS controller, the UI will not change - only the values displayed in the fields will change. If however you selected a target camera that has a lookat controller (not a PRS controller) the UI will change because a different set of parameters need to be displayed. Note that for items that are edited in the modifier branch this field can be ignored.

Reimplemented from Animatable.

EndEditParams()

virtual CoreExport void EndEditParams ( IObjParam *  ip, ULONG  flags, Animatable *  next  )

virtual

Remarks

This method is called when the user is finished editing an objects parameters. The system passes a flag into the EndEditParams() method to indicate if the rollup page should be removed. If this flag is TRUE, the plug-in must un-register the rollup page, and delete it from the panel.

Parameters

ip	An interface pointer. The developer may use the interface pointer to call methods such as DeleteRollupPage().
flags	The following flag may be set: END_EDIT_REMOVEUI If TRUE, the item's user interface should be removed.
next	Animatable pointer. Can be used in the motion and hierarchy branches of the command panel. It allows a plug-in to look at the ClassID of the next item that was being edited, and if it is the same as this item, to not replace the entire UI in the command panel. Note that for items that are edited in the modifier branch this field can be ignored.

ActivateSubobjSel()

CoreExport void ActivateSubobjSel ( int  level, XFormModes &  modes  )

virtual

When the user changes the selection of the sub-object drop down, this method is called to notify the plug-in.

This method should provide instances of a class derived from CommandMode to support move, rotate, non-uniform scale, uniform scale, and squash modes. These modes replace their object mode counterparts however the user still uses the move/rotate/scale tool buttons in the toolbar to activate them. If a certain level of sub-object selection does not support one or more of the modes NULL may be passed. If NULL is specified the corresponding toolbar button will be grayed out.

Parameters

level	The sub-object selection level the command modes should be set to support. A level of 0 indicates object level selection. If level is greater than or equal to 1 the index refers to the types registered by the object in the order they appeared in the list when registered by Interface::RegisterSubObjectTypes(). See Class Interface.
modes	The command modes to support

Sample Code:

void SimpleModBase::ActivateSubobjSel(int level, XFormModes& modes)
{
    switch ( level ) {
        case 1:                                   // Modifier box
            modes = XFormModes(moveMode,rotMode,nuscaleMode,uscaleMode,squashMode,NULL);
            break;
        case 2:                                   // Modifier Center
            modes = XFormModes(moveMode,NULL,NULL,NULL,NULL,NULL);
            break;
    }

SubObjectIndex()

CoreExport int SubObjectIndex ( HitRecord *  hitRec )

virtual

Returns the index of the sub-object element identified by the HitRecord hitRec.

See Class HitRecord. The sub-object index identifies a sub-object component. The relationship between the index and the component is established by the modifier. For example an edit modifier may allow the user to select a group of faces and these groups of faces may be identified as group 0, group 1, group 2, etc. Given a hit record that identifies a face, the edit modifier's implementation of this method would return the group index that the face belonged to.

Reimplemented from BaseObject.

GetSubObjectTMs()

CoreExport void GetSubObjectTMs ( SubObjAxisCallback *  cb, TimeValue  t, INode *  node, ModContext *  mc  )

virtual

When the user is in a sub-object selection level, the system needs to get the reference coordinate system definition from the current modifier being edited so that it can display the axis.

This method returns the axis system of the reference coordinate system. The plug-in enumerates its TMs and calls the callback cb once for each. See Sub-Object Coordinate Systems.

Parameters

cb	The callback object whose methods may be called.
t	The time to enumerate the TMs.
node	A pointer to the node.
mc	A pointer to the ModContext.

Reimplemented from BaseObject.

ShowEndResultChanged()

CoreExport void ShowEndResultChanged ( BOOL  showEndResult )

virtual

Remarks

This method is available in release 4.0 and later only.

This method is called by the system then the status of the Show End Result function changes (ie. the Show End Results button has been toggled on or off). Note that setting the state of the Show End Result is done through the Interface::SetShowEndResult() method.

Parameters:

BOOL showEndResult

This flag specifies the Show End Result status, which is TRUE if on; FALSE if off.

Reimplemented from BaseObject.

GetSubObjectCenters()

CoreExport void GetSubObjectCenters ( SubObjAxisCallback *  cb, TimeValue  t, INode *  node, ModContext *  mc  )

virtual

When the user is in a sub-object selection level, the system needs to get the reference coordinate system definition from the current modifier being edited so that it can display the axis.

This method specifies the position of the center. The plug-in enumerates its centers and calls the callback cb once for each.

Parameters

cb	The callback object whose methods may be called. See Class SubObjAxisCallback.
t	The time to enumerate the centers.
node	A pointer to the node.
mc	A pointer to the ModContext.

Reimplemented from BaseObject.

SelectSubComponent()

CoreExport void SelectSubComponent ( HitRecord *  hitRec, BOOL  selected, BOOL  all, BOOL  invert  )

virtual

This method is called to change the selection state of the component identified by hitRec.

Parameters

hitRec	Identifies the component whose selected state should be set. See Class HitRecord .
selected	TRUE if the item should be selected; FALSE if the item should be de-selected.
all	TRUE if all components in the HitRecord chain should be selected; FALSE if only the top-level HitRecord should be selected. (A HitRecord contains a Next() pointer; typically you want to do whatever you're doing to all the Next()'s until Next() returns NULL).
invert	This is set to TRUE when all is also set to TRUE and the user is holding down the Shift key while region selecting in select mode. This indicates the items hit in the region should have their selection state inverted

Reimplemented from BaseObject.

ClearSelection()

CoreExport void ClearSelection ( int  selLevel )

When this method is called the plug-in should respond by moving its selected sub-object components.

Parameters

t	The time of the transformation.
partm	The 'parent' transformation matrix. This matrix represents a transformation that would take points in the modifier's space and convert them into world space points. This is constructed as the node's transformation matrix times the inverse of the ModContext's transformation matrix. The node whose transformation is used is the node the user clicked on in the scene - modifiers can be instanced so there could be more than one node.
tmAxis	The matrix that represents the axis system. This is the space in which the transformation is taking place.
val	This value is a vector with X, Y, and Z representing the movement along each axis.
localOrigin	When TRUE the transformation is occurring about the sub-object's local origin.

Reimplemented from BaseObject.

Rotate()

CoreExport void Rotate ( TimeValue  t, Matrix3 &  partm, Matrix3 &  tmAxis, Quat &  val, BOOL  localOrigin = FALSE  )

virtual

When this method is called the plug-in should respond by rotating its selected sub-object components.

Parameters

t	The time of the transformation.
partm	The 'parent' transformation matrix. This matrix represents a transformation that would take points in the modifier's space and convert them into world space points. This is constructed as the node's transformation matrix times the inverse of the ModContext's transformation matrix. The node whose transformation is used is the node the user clicked on in the scene - modifiers can be instanced so there could be more than one node.
tmAxis	The matrix that represents the axis system. This is the space in which the transformation is taking place.
val	The amount to rotate the selected components.
localOrigin	When TRUE the transformation is occurring about the sub-object's local origin. Note: This information may be passed onto a transform controller (if there is one) so they may avoid generating 0 valued position keys for rotation and scales. For example if the user is rotating an item about anything other than its local origin then it will have to translate in addition to rotating to achieve the result. If a user creates an object, turns on the animate button, and rotates the object about the world origin, and then plays back the animation, the object does not do what the was done interactively. The object ends up in the same position, but it does so by both moving and rotating. Therefore both a position and a rotation key are created. If the user performs a rotation about the local origin however there is no need to create a position key since the object didn't move (it only rotated). So a transform controller can use this information to avoid generating 0 valued position keys for rotation and scales.

virtual

When this method is called the plug-in should respond by scaling its selected sub-object components.

Parameters

t	The time of the transformation.
partm	The 'parent' transformation matrix. This matrix represents a transformation that would take points in the modifier's space and convert them into world space points. This is constructed as the node's transformation matrix times the inverse of the ModContext's transformation matrix. The node whose transformation is used is the node the user clicked on in the scene - modifiers can be instanced so there could be more than one node.
tmAxis	The matrix that represents the axis system. This is the space in which the transformation is taking place.
val	This value is a vector with X, Y, and Z representing the scale along X, Y, and Z respectively.
localOrigin	When TRUE the transformation is occurring about the sub-object's local origin. See the note above in the Rotate method. The following methods may be used to receive notification about the starting and ending phases of transforming the item when in sub-object selection.

Reimplemented from BaseObject.

TransformStart()

CoreExport void TransformStart ( TimeValue  t )

virtual

This method is called before the first Move(), Rotate() or Scale() call and before a hold is in effect.

Parameters

t	The current time when this method is called.

Reimplemented from BaseObject.

TransformFinish()

CoreExport void TransformFinish ( TimeValue  t )

virtual

This method is called after the user has completed the Move(), Rotate() or Scale() operation and the undo object has been accepted.

Parameters

t	The current time when this method is called.

Reimplemented from BaseObject.

TransformCancel()

CoreExport void TransformCancel ( TimeValue  t )

virtual

This method is called when the transform operation is canceled by a right-click and the undo has been canceled.

Parameters

t	The current time when this method is called.

Reimplemented from BaseObject.

Eval()

CoreExport ObjectState Eval ( TimeValue  t )

virtual

This method is called to evaluate the object and return the result as an ObjectState.

When the system has a pointer to an object it doesn't know if it's a procedural object or a derived object. So it calls Eval() on it and gets back an ObjectState. A derived object managed by the system may have to call Eval() on its input for example. A plug-in (like a procedural object) typically just returns itself. A plug-in that does not just return itself is the Morph Object (/MAXSDK/SAMPLES/OBJECTS/MORPHOBJ.CPP). This object uses a morph controller to compute a new object and fill in an ObjectState which it returns.

Parameters

t	Specifies the time to evaluate the object.

Returns

The result of evaluating the object as an ObjectState.

Sample Code:

Typically this method is implemented as follows:

{ return ObjectState(this); }

Implements Object.

SupportsNamedSubSels()

BOOL SupportsNamedSubSels ( )

inlinevirtual

An object that supports sub-object selection can choose to support named sub object selection sets.

Methods in the interface passed to objects allow them to add items to the sub-object selection set drop down list. A modifier that wishes to support this capability maintains its list of named sub-object selections. When a user enters the sub-object selection mode, the modifier adds its named selection sets into the drop down (using Interface::AppendSubObjectNamedSelSet()).

Returns

true if the plug-in supports named sub-object selection sets, false otherwise.

Reimplemented from BaseObject.

{return TRUE;}

ActivateSubSelSet()

CoreExport void ActivateSubSelSet ( MSTR &  setName )

virtual

When the user chooses a name from the drop down list this method is called.

The plug-in should respond by selecting the set identified by the name passed.

Parameters

setName

The name of the set to select.

Reimplemented from BaseObject.

NewSetFromCurSel()

CoreExport void NewSetFromCurSel ( MSTR &  setName )

virtual

If the user types a new name into the named selection set drop down then this method is called.

The plug-in should respond by creating a new set and give it the specified name.

Parameters

setName

The name for the selection set.

Reimplemented from BaseObject.

RemoveSubSelSet()

CoreExport void RemoveSubSelSet ( MSTR &  setName )

virtual

If the user selects a set from the drop down and then chooses Remove Named Selections from the Edit menu this method is called.

The plug-in should respond by removing the specified selection set.

Parameters

setName

The selection set to remove.

Reimplemented from BaseObject.

SetupNamedSelDropDown()

CoreExport void SetupNamedSelDropDown ( )

virtual

To support the Edit Named Selections dialog, plug-ins must implement this method.

It is called to rebuild the named selection set drop down list. This is usually done by calling Interface::ClearSubObjectNamedSelSets() followed by calls to Interface:: AppendSubObjectNamedSelSet().

Reimplemented from BaseObject.

NumNamedSelSets()

CoreExport int NumNamedSelSets ( )

virtual

To support the Edit Named Selections dialog, plug-ins must implement this method.

Returns

the number of named selection sets.

Reimplemented from BaseObject.

GetNamedSelSetName()

CoreExport MSTR GetNamedSelSetName ( int  i )

virtual

To support the Edit Named Selections dialog, plug-ins must implement this method.

Parameters

i	The index of the selection set whose name is returned.

Returns

the name of the 'i-th' named selection set.

Reimplemented from BaseObject.

SetNamedSelSetName()

CoreExport void SetNamedSelSetName ( int  i, MSTR &  newName  )

virtual

To support the Edit Named Selections dialog, plug-ins must implement this method.

It sets the name of the selection set whose index is passed to the name passed. Note: Developers need to implement Undo / Redo for modifications to their named selection sets.

Parameters

i	The index of the selection set whose name is to be set.
newName	The new name for the selection set the plug-in should store.

Reimplemented from BaseObject.

NewSetByOperator()

CoreExport void NewSetByOperator ( MSTR &  newName, Tab< int > &  sets, int  op  )

virtual

To support the Edit Named Selections dialog, plug-ins must implement this method.

The user may bring up the Edit Named Selections dialog via the Edit / Edit Named Selection ... command. This dialog allows the user to create new selection sets using 'boolean' operations to the sets including 'Combine', 'Subtract (A-B)', 'Subtract (B-A)' and 'Intersection'. This method is called on the plug-in to generate a new selection set via one of these operations. This method assumes the developer will append a new seleciton set with the name passed. This will result in two sets with identical names. Then the system will call RemoveSubSelSet() afterwards, so that the first one that is found (the old one, since the new one was appended) will be deleted. Note: Developers need to implement Undo / Redo for modifications to their named selection sets. See /MAXSDK/SAMPLES/MODIFIERS/MESHSEL.CPP for an example.

Parameters

newName	The new name for the selection set is passed here.
sets	A table of the selection sets to operate on. There are sets.Count() sets in the table.
op	One of the following values defined in Arguments for BaseObject::NewSetByOperator()

Remarks

This method flips the normals of a specified patch or all selected patches. This method will save undo information and displays a prompt if patchIndex < 0 while there are no patches selected.

Parameters:

int patchIndex

The index of the patch for which to flip the normal. If this parameter is < 0, the normals of all selected patches will be flipped (if there are any selected).

Any vertices set to PVERT_COPLANAR that lie on the boundary between flipped and unflipped patches will have their type set to PVERT_CORNER. This is because attempting to compute normals of neighboring patches with opposite normals in order to get a proper plane often results in invalid normals being generated. Making the vertex a corner type prevents the problem. Any vertices not on the boundary between flipped and unflipped patches are left as is.

DoUnifyNormals()

CoreExport void DoUnifyNormals

(

)

Remarks

This method is available in release 4.0 and later only.

This method examines the selected patch set and attempts to make them all face the same direction. Preferred direction is arbitrary; the first selected patch encountered in each contiguous group determines the direction all patches in that group will attain.

Any vertices set to PVERT_COPLANAR that lie on the boundary between flipped and unflipped patches will have their type set to PVERT_CORNER. This is because attempting to compute normals of neighboring patches with opposite normals in order to get a proper plane often results in invalid normals being generated.
