Shader Family: Geometry

Output: Custom

This shader returns a copy of the input object, which must be a freeform-surface. It loops over all faces and adds a Bézier texture surface of degree 1 to each face as the last texture surface. The parameters and control points of the texture surfaces are chosen in such a way that there is an exact mapping of the parametric UV coordinates of the geometric approximation to the texture vertex coordinates; that is, the texture coordinates of the triangle vertices are the UV coordinates of the triangle vertex positions. The Bézier basis is always added to the copy of the object.

Name
