Detailed Description

This class maintains a list of the meshes and RenderMeshes used per instance. It acts as a factory class.

This is useful for Materials where a single material could be applied to multiple nodes, so a cache is needed so the material can pull the correct mesh data

virtual void SetMeshType ( IRenderMesh::MeshType type ) [pure virtual]

Search for all occurrences

Set the type of the mesh cache to maintain;.

Parameters:

type	Set the type of object to hold. This can be either a mesh or a quad.

virtual int SetCachedMNMesh	(	MNMesh *	mnMesh,
		INode *	node,
		TimeValue	time,
		bool &	meshChanged
	)		`[pure virtual]`

Fill up the cache with data from 3ds Max.

This method needs to be called when the node has actually changed. In 3ds Max 8 and before you could call this method at any time and the method would attempt to cache and maintain the data. However this would not work correctly with a MNMesh type object. Now the method expects to only update itself when the object changes. This is easily achieved by only calling this method when IStdDualVSCallback::InitValid() is called. To simply get the cache position for the node you can call this method with a NULL mnMesh pointer.

Parameters:

*mnMesh	The MNMesh to store in the cache. If this is NULL the system will return the cache entry only
*node	The node to store in the cache
time	The time to use in any evaluations
&meshChanged	If the mesh is different to that in the cache, this specifies the case.

Returns:: The position in the cache of the mesh/node combo

virtual int SetCachedMesh	(	Mesh *	mesh,
		INode *	node,
		TimeValue	time,
		bool &	meshChanged
