8.12.3.41 IfcTextureCoordinateGenerator
8.12.3.41.1 Semantic definition
The IfcTextureCoordinateGenerator describes a procedurally defined mapping function with input parameter to map 2D texture coordinates to 3D geometry vertices.
The TextureCoordinateGenerator supports the automatic generation of texture coordinates for geometric shapes.
The definitions of texturing within this standard have been developed in dependence on the texture component of X3D. See ISO/IEC 19775-1.2:2008 X3D Architecture and base components Edition 2, Part 1, 18 Texturing component for the definitions in the international standard. New entity in IFC2x2. CHANGE The attribute Texture has been deleted.8.12.3.41.2 Entity inheritance
