Detailed Description

Description:

This class provides a standard interface for modifiers and objects that use mesh deltas – specifically Edit Mesh and Editable Mesh. Both Edit Mesh and Editable Mesh have a current "state", which can be modified by MeshDeltas. In Editable Mesh, this "state" is an actual mesh, while in Edit Mesh, this is one MeshDelta per LocalModData. This class provides a standard interface to these: "MeshDeltaUser" and "MeshDeltaUserData".

Member Function Documentation

ApplyMeshDelta()

virtual void ApplyMeshDelta ( MeshDelta &  md, MeshDeltaUser *  mdu, TimeValue  t  )

pure virtual

Remarks

This method applies the MeshDelta. Everything that happens in Edit Mesh and Editable Mesh goes through this method. Note that in Edit Mesh, the MeshDeltaUserData (EditMeshData) is separate from the MeshDeltaUser (EditMeshMod), though in Editable Mesh, EditTriObject subclasses from both of them. There's essentially one mesh that can be edited per MeshDeltaUserData, so ApplyMeshDelta is the way to edit that mesh. ApplyMeshDelta typically handles adding Restore objects (if theHold.Holding()), clearing out any temporary local caches that are invalidated, and notifying the pipeline that the mesh has changed.

Parameters:

MeshDelta &md The mesh delta to apply. MeshDeltaUser *mdu Points to the mesh delta user. TimeValue t The time to apply the mesh delta.

GetCurrentMDState()

virtual MeshDelta * GetCurrentMDState ( )

inlinevirtual

Remarks

Returns a pointer to the MeshDelta object for this application of the Edit Mesh modifier. This is only non-NULL in Edit Mesh.

Default Implementation:

{ return NULL; }

{ return NULL; } // only non-null in Edit Mesh
