Detailed Description

Description:: Methods of this class may be used to enumerate the scene and to flag certain nodes in the scene. Nodes chosen by the plug-in may be flagged using the EnumTree() method. Selected nodes may be flagged using FlagFGSelected(). Animated nodes may be flagged using FlagFGAnimated() and dependent nodes may be flagged using FlagFGDependent().

Member Function Documentation

virtual int EnumTree ( ITreeEnumProc * proc ) [pure virtual]

Remarks:: Implemented by the System.

This may be called to enumerate every INode in the scene. The callback may flag any of these nodes (using INode::FlagForeground()).

Parameters:

proc	This callback object is called once for each INode in the scene.

Returns:: Nonzero if the process was aborted by the callback (TREE_ABORT); otherwise 0.

virtual void FlagFGSelected ( TimeValue t ) [pure virtual]

Remarks:: Implemented by the System.

Flags all selected nodes in the scene.

Parameters:

t	The time to flag the nodes.

virtual void FlagFGAnimated ( TimeValue t ) [pure virtual]

Remarks:: Implemented by the System.

Flags all animated nodes in the scene.

Parameters:

t	The time to flag the nodes.

virtual void FlagFGDependent	(	TimeValue	t,
		BaseObject *	obj
	)		`[pure virtual]`

Remarks:: Implemented by the System.

Flags nodes that are dependent on the given object.

Parameters:

t	The time to flag the nodes.
obj	The object whose dependent nodes should be flagged.
