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.

#	Attribute	Type	Description
IfcTextureCoordinate (1)
1	Maps	LIST [1:?] OF IfcSurfaceTexture	Reference to the one (or many in case of multi textures with identity transformation to geometric surfaces) subtype(s) of IfcSurfaceTexture that are mapped to a geometric surface by the texture coordinate transformation.

2	Mode	IfcLabel	The Mode attribute describes the algorithm used to compute texture coordinates. The following modes are recommended: COORD: use vertex coordinates COORD-EYE: use vertex coordinates transformed to camera space
3	Parameter	OPTIONAL LIST [1:?] OF IfcReal	The parameters used as arguments by the function as specified by Mode. IFC4-CHANGE : Data type restricted to REAL. IFC4.3.0.0-DEPRECATION This attribute is deprecated and shall no longer be used.
