Detailed Description

See also

Class GeomObject, Class Mesh.

Description:

This is a base class for creating procedural objects. This class implements many of the methods required to create a procedural object. The only limitation for a procedural object using SimpleObjectBase as a base class is that it must represent itself with a mesh.

Data Members:

Note: Methods of the base class refer to these data members. For example the base class implementations of the bounding box methods use the mesh data member. Therefore the plug-in derived from SimpleObjectBase must use these same data members.

Mesh mesh;

The mesh object that is built by BuildMesh().

Interval ivalid;

The validity interval for the mesh. This interval is used to determine how BuildMesh() is called. If this interval is not set BuildMesh() will be called over and over as the system won't know when the mesh is valid or not. Make sure you set this interval to accurately reflect the validity interval for the mesh.

BOOL suspendSnap;

If TRUE, this causes no snapping to occur. This is commonly used to prevent an object from snapping to itself when it is creating. For example, in the mouse proc used to create an object, the following code is often used when snapping mouse points:

ob->suspendSnap = TRUE;

p0 = vpt->SnapPoint(m,m,nullptr,SNAP_IN_PLANE);

This disables snapping temporarily to keep the object from snapping to itself.

Procedural Object plug-ins which subclass off SimpleObjectBase must implement these methods. The default implementations are noted.

BeginEditParams()

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()

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.

Reimplemented from Animatable.

HitTest()

CoreExport int HitTest ( TimeValue  t, INode *  inode, int  type, int  crossing, int  flags, IPoint2 *  p, ViewExp *  vpt  )

virtual

This method is called to determine if the specified screen point intersects the item.

The method returns nonzero if the item was hit; otherwise 0.

Parameters

t	The time to perform the hit test.
inode	A pointer to the node to test.

Snap()

CoreExport void Snap ( TimeValue  t, INode *  inode, SnapInfo *  snap, IPoint2 *  p, ViewExp *  vpt  )

virtual

Checks the point passed for a snap and updates the SnapInfo structure.

Note

Developers wanting to find snap points on an Editable Mesh object should see the method XmeshSnap::Snap() in /MAXSDK/SAMPLES/SNAPS/XMESH/XMESH.CPP.

Parameters

t	The time to check.
inode	The node to check.
snap	The snap info structure to update.
p	The screen point to check.
vpt	An interface pointer that may be used to call methods associated with the viewports.

Reimplemented from BaseObject.

Display()

CoreExport int Display ( TimeValue  t, INode *  inode, ViewExp *  vpt, int  flags  )

virtual

This is called by the system to have the item display itself (perform a quick render in viewport, using the current TM).

Note: For this method to be called the object's validity interval must be invalid at the specified time t. If the interval is valid, the system may not call this method since it thinks the display is already valid.

Parameters

t	The time to display the object.
inode	The node to display.
vpt	An interface pointer that may be used to call methods associated with the viewports.
flags	See Display Flags.

Returns

Default return value is -1, means this object doesn't have display function. 0 means it didn't draw anything in current frame. Otherwise return positive values..

Reimplemented from BaseObject.

UpdatePerNodeItems()

CoreExport bool UpdatePerNodeItems ( const MaxSDK::Graphics::UpdateDisplayContext &  updateDisplayContext, MaxSDK::Graphics::UpdateNodeContext &  nodeContext, MaxSDK::Graphics::IRenderItemContainer &  targetRenderItemContainer  )

virtual

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.

InitNodeName()

void InitNodeName ( MSTR &  s )

inlinevirtual

This is the default name of the node when it is created.

Parameters

s	The default name of the node is stored here.

Reimplemented from GeomObject.

{s = GetObjectName(true);}

ObjectValidity()

CoreExport Interval ObjectValidity ( TimeValue  t )

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.

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().

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.

Default Implementation:

{ return 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.

class ObjectConverter for additional details on converting objects between types.

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;
    }
}

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.

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()

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.

GetDeformBBox()

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

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.

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.

Reimplemented from GeomObject.

FreeCaches()

CoreExport void FreeCaches ( )

virtual

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.

GetClassName()

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

inlineoverridevirtual

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 ReferenceTarget.

{s = GetObjectName(localized);}

GetInterface() [1/2]

virtual CoreExport BaseInterface* GetInterface ( Interface_ID  id )

virtual

Inherited from Animatable.

Returns a pointer to the Base Interface for the interface ID passed.

Parameters

id	- The unique ID of the interface to get

Returns

A Pointer to the Interface

Reimplemented from Object.

GetInterface() [2/2]

CoreExport void* GetInterface ( ULONG  id )

virtual

Inherited from Animatable.

Returns a pointer to the interface.

Parameters

id	- The id of the interface.

Returns

A Pointer to the Interface

Reimplemented from Object.

NotifyRefChanged()

CoreExport 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.

Reimplemented in SimpleObject.

BuildMesh()

virtual void BuildMesh ( TimeValue  t )

pure virtual

Remarks

This method is called to build the mesh representation of the object using its parameter settings at the time passed. The plug-in should use the data member mesh to store the built mesh.

Parameters:

TimeValue t

The time at which to build the mesh.

Implemented in MSSimpleObjectXtnd, and MSPluginSimpleObject.

OKtoDisplay()

virtual BOOL OKtoDisplay ( TimeValue  t )

inlinevirtual

Remarks

This method returns a BOOL to indicate if it is okay to draw the object at the time passed. Normally it is always OK to draw the object, so the default implementation returns TRUE. However for certain objects it might be a degenerate case to draw the object at a certain time (perhaps the size went to zero for example), so these objects could return FALSE.

Parameters:

TimeValue t

The time at which the object would be displayed.

Default Implementation:

{ return TRUE; }

Returns

TRUE if the object may be displayed; otherwise FALSE.

Reimplemented in MSSimpleObjectXtnd, and MSPluginSimpleObject.

{return TRUE;}

InvalidateUI()

virtual void InvalidateUI ( )

inlinevirtual

Remarks

This is called if the user interface parameters needs to be updated because the user moved to a new time. The UI controls must display values for the current time.

Example:

If the plug-in uses a parameter map for handling its UI, it may call a method of the parameter map to handle this:

pmapParam->Invalidate();

If the plug-in uses ParamBlock2, it may call a method on the ParamBlockDesc2 to handle this:

box_param_blk.InvalidateUI(pblock2->LastNotifyParamID());

If the plug-in does not use parameter maps, it should call the SetValue() method on each of its controls that display a value, for example the spinner controls. This will cause to the control to update the value displayed. The code below shows how this may be done for a spinner control. Note that ip and pblock are assumed to be initialized interface and parameter block pointers:

void foo(IObjParam* ip, IParamBlock* pblock)
{
    float newval;
    Interval valid = FOREVER;
    TimeValue t = ip->GetTime();
    // Get the value from the parameter block at the current time.
    pblock->GetValue( PB_ANGLE, t, newval, valid );
    // Set the value. Note that the notify argument is passed as FALSE.
    // This ensures no messages are sent when the value changes.
    angleSpin->SetValue( newval, FALSE );
}

Reimplemented in MSSimpleObjectXtnd, and MSPluginSimpleObject.
