8.12.3.40.1 Semantic definition
The IfcTextureCoordinate is an abstract supertype of the different kinds to apply texture coordinates to geometries. For vertex based geometries an explicit assignment of 2D texture vertices to the 3D geometry points is supported by the subtype IfcTextureMap, in addition there can be a procedural description of how texture coordinates shall be applied to geometric items. If no IfcTextureCoordinate is provided for the IfcSurfaceTexture, the default mapping shall be used.
