IfcTextureVertexList | ADDED |
The IfcTextureVertexList defines an ordered collection of texture vertices. Each texture vertex is a two-dimensional vertex provided by a fixed list of two texture coordinates. The attribute TexCoordsList is a two-dimensional list, where
NOTE The IfcTextureVertexList is introduced to provide a compact representation of an indexable representation of texture coordinates for texture maps in tessellated items.
