Member Function Documentation

virtual RixSubdivisionFace* RixSubdivisionMesh::GetFace (  int  id  )  [pure virtual]

Returns the face with the given ID on the mesh. Returns NULL if no face with that ID exists on the mesh.

virtual RtToken RixSubdivisionMesh::GetMask (   )  [pure virtual]

Returns the type of subdivision used in the mesh.

virtual int RixSubdivisionMesh::GetNumCoarseFaces (   )  [pure virtual]

Returns the number of top level faces on the mesh.

virtual int RixSubdivisionMesh::GetNumFaces (   )  [pure virtual]

Returns the total number of faces on the mesh, including faces created through subdivision.

virtual int RixSubdivisionMesh::GetNumVertices (   )  [pure virtual]

Returns the number of vertices on the mesh.

virtual void RixSubdivisionMesh::GetPackedVertexDataIndices (  int  depth, std::vector< int > &  vertexcounts, std::vector< int > &  vertices )  [pure virtual]

Requests the number of vertices in each face in the mesh at the given depth, as well as the data indices of those vertices. The data indices are returned in packed form.

virtual bool RixSubdivisionMesh::GetPackedVertexValues (  const RtToken  name, int  width, const RtToken  space, std::vector< float > &  data )  [pure virtual]

Requests the current values of a primitive variable at all available vertices on the mesh. The variable cannot be a string type, and must be of detail varying, vertex, or facevarying. Returns true if the data exists with the given name and width (in floats), false otherwise. Point like data types will be transformed to the requested space.

virtual RixSubdivisionVertex* RixSubdivisionMesh::GetVertex (  int  id  )  [pure virtual]

Returns the vertex with the given ID on the mesh. Returns NULL if no face with that ID exists on the mesh.

virtual void RixSubdivisionMesh::Subdivide (  int  depth  )  [pure virtual]

Subdivides the entire mesh to the indicated depth.
