Member Function Documentation

DeleteThis()

void DeleteThis ( )

inlinevirtual

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

See Memory Management.

Required DLL Functions, Class ClassDesc.

Reimplemented from MSPluginModifier.

{ MSPlugin::DeleteThis(); }

get_delegate()

ReferenceTarget* get_delegate ( )

inlinevirtual

Reimplemented from MSPluginModifier.

{ return delegate; } 

GetClassName()

void GetClassName ( MSTR &  s, bool  localized  ) 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 MSPluginModifier.

{ s = (localized) ? pc->ClassName() : pc->NonLocalizedClassName(); }

ClassID()

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

Class ClassID, class ID definitions in plugapi.h.

Reimplemented from MSPluginModifier.

{ return pc->class_id; }

SuperClassID()

SClass_ID SuperClassID ( )

inlinevirtual

Retrieves a constant representing the type of the plugin.

Returns

A super class id that uniquely identifies the type (category) of the plugin. Note that several plugin classes can be of the same type, thus return the same super class id. Plugins are uniquely identified by their class ids.

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 MSPluginModifier.

{ delegate->FreeCaches(); }         

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 MSPluginModifier.

{ return pblocks.Count() + 1; }  

SubAnim()

Animatable* SubAnim ( int  i )

inlinevirtual

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 MSPluginModifier.

{ if (i == 0) return delegate; else return pblocks[i-1]; }

SubAnimName()

MSTR SubAnimName ( int  i, bool  localized = true  )

inlineoverridevirtual

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 MSPluginModifier.

    {
        if (i == 0)
        {
            return delegate->GetObjectName(localized);
        }
        else if (pblocks[i - 1]->GetDesc()->local_name != 0)
        {
            return localized ? pblocks[i - 1]->GetLocalName() : pblocks[i - 1]->GetDesc()->int_name.data();
        }
        else
        {
            return _T("");
        }
    }

NumParamBlocks()

int NumParamBlocks ( )

inlinevirtual

Remarks

This method is available in release 3.0 and later only.

This method returns the number of ParamBlock2s in this instance.

Default Implementation:

{ return 0; }

Reimplemented from MSPluginModifier.

{ return pblocks.Count(); }

GetParamBlock()

IParamBlock2* GetParamBlock ( int  i )

inlinevirtual

An object or modifier should implement this method if it wishes to make its parameter block available for other plug-ins to access it.

The system itself doesn't actually call this method. This method is optional.

Returns

A pointer to the item's parameter block. See Class IParamArray.

Reimplemented from MSPluginModifier.

{ return pblocks[i]; }

GetParamBlockByID()

IParamBlock2* GetParamBlockByID ( BlockID  id )

inlinevirtual

Remarks

This method returns a pointer to the ParamBlock2 as specified by the ID passed (or NULL if not available).

Parameters

id	The BlockID of the ParamBlock2 instance.

Default Implementation:

{ return NULL; }

Reimplemented from MSPluginModifier.

{ return MSPlugin::GetParamBlockByID(id); }

GetInterface() [1/2]

void* GetInterface ( ULONG  id )

inlinevirtual

Inherited from Animatable.

Returns a pointer to the interface.

Parameters

id	- The id of the interface.

Returns

A Pointer to the Interface

Reimplemented from MSPluginModifier.

{ if (id == I_MAXSCRIPTPLUGIN) return (MSPlugin*)this; else return MSPluginModifier::GetInterface(id); }

NumRefs()

int NumRefs ( )

virtual

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 MSPluginModifier.

GetReference()

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 MSPluginModifier.

SetReference()

virtual 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 MSPluginModifier.

Clone()

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 MSPluginModifier.

GetObjectName()

const MCHAR* GetObjectName ( bool  localized = true ) const

inlineoverridevirtual

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 MSPluginModifier.

{ return pc->class_name->to_string(); } // localized name

BeginEditParams()

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 MSPluginModifier.

EndEditParams()

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 MSPluginModifier.

HitTest() [1/2]

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

inlinevirtual

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.
type	The type of hit testing to perform. See Scene and Node Hit Test Types. for details.
crossing	The state of the crossing setting. If TRUE crossing selection is on.
flags	The hit test flags. See Scene and Node Hit Testing Flags for details.
p	The screen point to test.
vpt	An interface pointer that may be used to call methods associated with the viewports.

Returns

Nonzero if the item was hit; otherwise 0.

Reimplemented from MSPluginModifier.

                        { return delegate->HitTest(t, inode, type, crossing, vflags, p, vpt); }

Display() [1/2]

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 MSPluginModifier.

SetExtendedDisplay()

void SetExtendedDisplay ( int  flags )

inlinevirtual

This method is used for storing mode-dependent display attributes.

Before an object's Display() method is called, the appropriate bits of the extended display flag variable are set and this method is called. After that, the Display() method is called. If the object must display itself differently based on the settings of the extended display bit fields, then the object must save the flags passed into the this method. Otherwise, there is no need for the object to store the flags.

Parameters

flags

The flags to store.

Reimplemented from BaseObject.

{ delegate->SetExtendedDisplay( vflags); }      // for setting mode-dependent display attributes

GetWorldBoundBox() [1/2]

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

inlinevirtual

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 MSPluginModifier.

{ delegate->GetWorldBoundBox(t, inode, vpt, box); }

GetLocalBoundBox()

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

inlinevirtual

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 MSPluginModifier.

{ delegate->GetLocalBoundBox(t, inode, vpt,  box ); }

Snap()

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

inlinevirtual

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 MSPluginModifier.

{ delegate->Snap(t, inode, snap, p, vpt); }

GetCreateMouseCallBack()

CreateMouseCallBack* GetCreateMouseCallBack ( )

inlinevirtual

This method allows the system to retrieve a callback object used in creating an object in the 3D viewports.

This method returns a pointer to an instance of a class derived from CreateMouseCallBack. This class has a method proc() which is where the programmer defines the user/mouse interaction during the object creation phase.

Returns

A pointer to an instance of a class derived from CreateMouseCallBack.

Reimplemented from MSPluginModifier.

{ return delegate->GetCreateMouseCallBack(); } 

ChangeTopology()

BOOL ChangeTopology ( )

inlinevirtual

This method asks the question of an object or modifier "Do you change topology"? An object or modifier returns TRUE if it is capable of changing topology when its parameters are being edited; otherwise FALSE.

When an item is selected for editing, and there is a modifier in the pipeline that depends on topology, the system calls this method to see if it may potentially change the topology. If this method returns TRUE the system will put up a warning message indicating that a modifier exists in the stack that depends on topology.

Reimplemented from BaseObject.

{return delegate->ChangeTopology();}

Move()

void Move ( TimeValue  t, Matrix3 &  partm, Matrix3 &  tmAxis, Point3 &  val, BOOL  localOrigin = FALSE  )

inlinevirtual

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.

{ delegate->Move( t, partm, tmAxis, val, localOrigin ); }

Rotate()

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

inlinevirtual

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.

Reimplemented from BaseObject.

{ delegate->Rotate( t, partm, tmAxis, val, localOrigin ); }

Scale()

void Scale ( TimeValue  t, Matrix3 &  partm, Matrix3 &  tmAxis, Point3 &  val, BOOL  localOrigin = FALSE  )

inlinevirtual

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.

{ delegate->Scale( t, partm, tmAxis, val, localOrigin ); }

CloneSelSubComponents()

void CloneSelSubComponents ( TimeValue  t )

inlinevirtual

This method is called to make a copy of the selected sub-object components of the item.

If this is called on an object, the selection level of the object is used to determine which type of sub-objects are cloned. For instance in a Mesh, the selection level determines if selected verticies, edges or faces are cloned. If this is called on a Modifier then the selection level of the modifier is used. Modifiers call Interface::GetModContexts() to get a list of ModContexts, one for each object the modifier is applied to. Then the selected sub-objects are cloned for each object in the list.

Parameters

t	The time at which to clone the selected sub-object components.

Reimplemented from BaseObject.

{ delegate->CloneSelSubComponents( t); }

AcceptCloneSelSubComponents()

void AcceptCloneSelSubComponents ( TimeValue  t )

inlinevirtual

This method is called when the user mouses up after shift-cloning a sub-object selection.

Parameters

t	The time at which the clone of the selected components is being done.

Reimplemented from BaseObject.

{ delegate->AcceptCloneSelSubComponents( t); }

SelectSubComponent()

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

inlinevirtual

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.

                                                                                   { delegate->SelectSubComponent(hitRec, selected, all, invert); }

ClearSelection()

void ClearSelection ( int  selLevel )

Specifies the selection level to invert.

Reimplemented from BaseObject.

{ delegate->InvertSelection( selLevel); }

SubObjectIndex()

int SubObjectIndex ( HitRecord *  hitRec )

inlinevirtual

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.

{return  delegate->SubObjectIndex(hitRec);}               

ActivateSubobjSel()

void ActivateSubobjSel ( int  level, XFormModes &  modes  )

inlinevirtual

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;
    }
    NotifyDependents(FOREVER,PART_DISPLAY,REFMSG_CHANGE);
}

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  delegate->SupportsNamedSubSels();}

ActivateSubSelSet()

void ActivateSubSelSet ( MSTR &  setName )

inlinevirtual

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.

{ delegate->ActivateSubSelSet(setName); }

NewSetFromCurSel()

void NewSetFromCurSel ( MSTR &  setName )

inlinevirtual

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.

{ delegate->NewSetFromCurSel(setName); }

RemoveSubSelSet()

void RemoveSubSelSet ( MSTR &  setName )

inlinevirtual

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.

{ delegate->RemoveSubSelSet(setName); }

SetupNamedSelDropDown()

void SetupNamedSelDropDown ( )

inlinevirtual

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.

{ delegate->SetupNamedSelDropDown(); }

NumNamedSelSets()

int NumNamedSelSets ( )

inlinevirtual

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

Returns

the number of named selection sets.

Reimplemented from BaseObject.

{return  delegate->NumNamedSelSets();}

GetNamedSelSetName()

MSTR GetNamedSelSetName ( int  i )

inlinevirtual

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.

{return  delegate->GetNamedSelSetName( i);}

SetNamedSelSetName()

void SetNamedSelSetName ( int  i, MSTR &  newName  )

inlinevirtual

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.

{ delegate->SetNamedSelSetName( i, newName); }

NewSetByOperator()

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

inlinevirtual

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()

Reimplemented from BaseObject.

{ delegate->NewSetByOperator(newName, sets, op); }

GetSubObjectCenters()

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

inlinevirtual

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.

{ delegate->GetSubObjectCenters(cb, t, node, mc); }

GetSubObjectTMs()

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

inlinevirtual

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.

{ delegate->GetSubObjectTMs( cb, t, node, mc); }                          

HasUVW() [1/2]

BOOL HasUVW ( )

inlinevirtual

Call this method to find out if the object has UVW coordinates.

This method returns TRUE if the object has UVW coordinates; otherwise FALSE. In 3ds Max 2.0 and later there is code in the renderer that will automatically turn on the UVW coordinates of the base object if UV's are missing (and needed). The base object has to implement two simple methods to make this work: HasUVW() and SetGenUVW(). Developers are encouraged to put these methods in their objects: it makes using the program easier for the user. If they are not implemented, it doesn't cause any real harm: it will just operate as before and put up the missing UVW's message. Here is how the procedural sphere implements these methods:

BOOL SphereObject::GetGenUVW()
{
    BOOL genUVs;
    Interval v;
    pblock->GetValue(PB_GENUVS, 0, genUVs, v);
    return genUVs;
}
 
void SphereObject::SetGenUVW(BOOL sw)
{
    if (sw==GetGenUVW()) return;
    pblock->SetValue(PB_GENUVS,0, sw);
}

Important Note: The pblock->SetValue() will cause a call to NotifyDependents(FOREVER, PART_TEXMAP, REFMSG_CHANGE), which will invalidate the UVW cache. It is essential that this call be made, so if the 'generate UVW' boolean is not handled by a parameter block, then NotifyDependents() needs to be called explicitly. Also Note: For "modifiable objects" that pass up the pipeline getting modified, such as TriObject, EditTriObject, etc., which cannot generate their own UVWs, but can carry them in their data structures, only this HasUVW() method needs to be implemented. For example, here is the implementation for TriObject: BOOL TriObject::HasUVW() { return mesh.tvFace?1:0; }

Reimplemented from MSPluginModifier.

{ return delegate->HasUVW(); }

HasUVW() [2/2]

BOOL HasUVW ( int  mapChannel )

inlinevirtual

Call this method to find out if the object is has UVW coordinates for the specified mapping channel.

This method returns TRUE if the object has UVW coordinates; otherwise FALSE. See the method HasUVW() above for more details.

Parameters

mapChannel

See Mapping Channels.

Reimplemented from BaseObject.

{ return delegate->HasUVW (mapChannel); }

SetGenUVW() [1/2]

void SetGenUVW ( BOOL  sw )

inlinevirtual

This method is called to change the state of its Generate UVW boolean.

If the state changes, the object must send a REFMSG_CHANGE up the pipeline by calling NotifyDependents(). This applies to map channel 1.

Parameters

sw	The new state for the generate UVW flag.

Reimplemented from MSPluginModifier.

{ delegate->SetGenUVW( sw);   } // applies to mapChannel 1

SetGenUVW() [2/2]

void SetGenUVW ( int  mapChannel, BOOL  sw  )

inlinevirtual

This method is called to change the state of its Generate UVW boolean for the specified mapping channel.

If the state changes, the object must send a REFMSG_CHANGE up the pipeline by calling NotifyDependents().

Parameters

mapChannel	The mapping channel index. See Mapping Channels.
sw	The new state for the generate UVW flag.

Reimplemented from BaseObject.

{ delegate->SetGenUVW ( mapChannel, sw); }

ShowEndResultChanged()

void ShowEndResultChanged ( BOOL  showEndResult )

inlinevirtual

This method notifies the BaseObject that the end result display has been switched (the "Show End Result" button has been toggled).

Sometimes this is needed for display changes. This method is implemented in Edit Mesh, which uses it as shown below: void EditMeshMod::ShowEndResultChanged(BOOL showEndResult) {

NotifyDependents(FOREVER, PART_DISPLAY, REFMSG_CHANGE);

}

This allows the Edit Mesh modifier to update itself in repsonse to a user click of the "Show End Result" button in the modifier panel.

Parameters

showEndResult

TRUE if Show End Result is on; FALSE if off.

Reimplemented from BaseObject.

{ delegate->ShowEndResultChanged ( showEndResult);  }

LocalValidity()

Interval LocalValidity ( TimeValue  t )

virtual

This method returns the validity interval of a modifier.

It is simply the combination of the validity of all the modifier's parameters. It's used to determine when to cache in the pipeline, but is not directly responsible for determining when ModifyObject() is called. ModifyObject() is called when the pipeline needs to be evaluated either because someone sent a REFMSG_CHANGE message or the validity of the object does not include the current time.

If a modifier is not animated it's OK to simply return FOREVER from

this method. In the case where the modifier changes because a user changes a non-animated control in the user interface (for instance a check box), you can cause reevaluation by notifying your dependents of the change, i.e.:

NotifyDependents(FOREVER, PART_ALL, REFMSG_CHANGE);

Parameters

t	The time to calculate the Interval.

Advanced Topics on Intervals.

Reimplemented from MSPluginModifier.

ChannelsUsed()

ChannelMask ChannelsUsed ( )

inlinevirtual

These are channels that the modifier needs in order to perform its modification.

This should at least include the channels specified in ChannelsChanged() but may include more. Note that ChannelsUsed() is called many times but the channels returned should not change on the fly.

Returns

The channels required. See Object Channels.

Sample Code:

{ return GEOM_CHANNEL|TOPO_CHANNEL; }

Reimplemented from MSPluginModifier.

{ return delegate->ChannelsUsed(); }

ChannelsChanged()

ChannelMask ChannelsChanged ( )

inlinevirtual

These are the channels that the modifier actually modifies.

Note that ChannelsChanged() is called many times but the channels returned should not change on the fly.

Returns

The channels that are changed. See Object Channels

Reimplemented from MSPluginModifier.

{ return delegate->ChannelsChanged(); }

NotifyInputChanged()

void NotifyInputChanged ( const Interval &  changeInt, PartID  partID, RefMessage  message, ModContext *  mc  )

inlinevirtual

This method is called when an item in the modifier stack before this modifier sends a REFMSG_CHANGE message via NotifyDependents().

Consider the following example: Assume the modifier stack contains a Sphere Object, then a Bend, then a Edit Mesh. The Edit Mesh modifier does not have a reference to the Bend or the Sphere because it does not officially depend on these items. However it does depend on them in a certain sense, because it modifies the data that these items produce. So, if they change it may affect the modifier. A modifier may build a cache based on its input object. The modifier needs a way to know when to discard this cache because the input object has changed. Whenever one of the items before this modifier in the stack sends out a REFMSG_CHANGE message via NotifyDependents() to indicate it has changed this method is called. The modifier may respond in a way appropriate to it, for example by discarding its cache of the input object. It is not legal, to issue a NotifyDependent()'s in the NotifyInputChanged() method of a modifier, without checking for reentrancy. Imagine, you have an instanced modifier applied to the same object in the stack. Sending a refmsg from the NotifyInputChanged method will cause an endless loop. Simply putting a guard in, that checks for reentrancy should get rid of the problem.

Parameters

changeInt	This is the interval from the message. It is reserved for future use - now it will always be FOREVER.
partID	This is the partID from the message.
message	This is the message sent.
mc	The ModContext for the pipeline that changed. If a modifier is applied to multiple objects, then there are ModApps in each pipeline that it is applied to. These ModApps are pointing to the same modifier. Consider the following example: Say you apply a Bend modifier to a Sphere, a Cylinder and a Box object. There are three ModApps but only one Bend modifier. Then you go to the Sphere and adjust its Radius. This will cause NotifyInputChanged() to be called on the Bend because the Bend's input changed. However only one of its inputs changed - only the Sphere changed and not the Cylinder or the Box. Therefore NotifyInputChanged() will be called once, and the ModContext passed in will be for the Sphere's changed pipeline. It is possible that all three objects could change at the same time. If an instanced float controller was assigned to the radius, width, and height - one parameter for each object - then the controller was adjusted in the function curve editor, all three items would change. In this case NotifyInputChanged() would be called three times on the Bend. Once for each pipeline, once with each ModContext.

Reimplemented from MSPluginModifier.

{ delegate->NotifyInputChanged(changeInt, partID, message, mc); }

ModifyObject()

void ModifyObject ( TimeValue  t, ModContext &  mc, ObjectState *  os, INode *  node  )

virtual

This is the method that actually modifies the input object.

This method is responsible for altering the object and then updating the validity interval of the object to reflect the validity of the modifier.

Parameters

t	The time at which the modification is being done.
mc	A reference to the ModContext.
os	The object state flowing through the pipeline. This contains a pointer to the object to modify.
node	The node the modifier is applied to. This parameter is always NULL for Object Space Modifiers and non-NULL for World Space Modifiers (Space Warps). This is because a given WSM is only applied to a single node at a time whereas an OSM may be applied to several nodes. This may be used for example by particle system space warps to get the transformation matrix of the node at various times.

DependOnTopology()

BOOL DependOnTopology ( ModContext &  mc )

inlinevirtual

Modifiers that place a dependency on topology should return TRUE for this method.

An example would be a modifier that stores a selection set base on vertex indices. This modifier depends on the indices being intact for it to operate correctly.

Parameters

mc	Reference to the ModContext.

Returns

TRUE if the modifier depends on topology; otherwise FALSE.

Reimplemented from MSPluginModifier.

{ return delegate->DependOnTopology(mc); }

InputType()

Class_ID InputType ( )

inlinevirtual

This is the type of object that the modifier knows how to modify.

Simple modifiers that just modify points of an object can operate on generic 'Deformable' objects. Deformable objects are any type of object that has points. A modifier could also work on a particular type of object such as a TriObject or PatchObject.

Returns

The Class_ID of the item. You can request any Class_ID for your input type. For example, Class_ID(OMNI_LIGHT_CLASS_ID, 0). See Class IDs defined in plugapi.h>.

Reimplemented from MSPluginModifier.

{ return delegate->InputType(); }

SaveLocalData()

IOResult SaveLocalData ( ISave *  isave, LocalModData *  ld  )

inlinevirtual

When a 3ds Max file is being saved, this method is called so that the modifier can save the localData structure that is hung off each ModContext.

If the modifier doesn't store any data in the ModContext it can ignore this method.

Parameters

isave	You may use this pointer to call methods of ISave to write data.
ld	Pointer to the LocalModData for the modifier.

Returns

One of the following values: IO_OK, IO_ERROR.

Reimplemented from MSPluginModifier.

{ return delegate->SaveLocalData(iSave, ld); }

LoadLocalData()

IOResult LoadLocalData ( ILoad *  iload, LocalModData **  pld  )

inlinevirtual

When a 3ds Max file is being loaded, this method is called so that the modifier can load the LocalModData structure that is hung off each ModContext.

If the modifier doesn't store any data in the ModContext it can ignore this method.

Parameters

iload	You may use this pointer to call methods of ILoad to read data.
pld	A pointer to a pointer in the ModContext. The modifier must set this pointer to point at a new LocalModData derived class.

Returns

One of the following values: IO_OK, IO_ERROR.

Reimplemented from MSPluginModifier.

{ return delegate->LoadLocalData(iLoad, pld); }
