8.12.3.43 IfcTextureCoordinateIndicesWithVoids
8.12.3.43.1 Semantic definition
The IfcTextureCoordinateIndicesWithVoids is a subtype of IfcTextureCoordinateIndices to be used to provide texture coordinates to polygonal faces with inner loops. The two dimensional list of TexCoordIndex holds the indices into the IfcTextureVertexList that correspond to the list of CoordIndex at TexCoordsOf where:
- the first dimension corresponds to the list position of the inner loops at IfcIndexedPolygonalFaceWithVoids referenced by TexCoordsOf
- the second dimension corresponds to the list position of the vertices at the nth inner loop at IfcIndexedPolygonalFaceWithVoids
