Detailed Description

IRdVertexTopologyData is one of two temporary streams that hold vertex topology information for mesh. Data stream holds lists if triangles that are referenced by IRdVertexTopologyInfo stream.

This is a temporary stream, that should be used stored inside system scratch-pad, instead of mesh streams. If you want to add stream to mesh, it can be stored in Vertex stream group. Stream is identified by STREAMID_VERTEX_TOPOLOGY_DATA id.

(

[in] RtDWORD

dwNumTripleIndices

)

Set number of triangles.

Parameters:

dwNumTripleIndices

[in] Set number of triangles/triple indices.

Returns:

standard HRESULT processing can be applied to returned value
