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:
