UV Mapping

### 2.6.7 UV Mapping

The `uv_mapping` feature gives the possibility to wrap a 2D texture, taken from the xy-plane, around an object in such a way that it smoothly follows the surface of the object. uv_mapping is supported by the following objects:

- sphere
- box
- lathe
- sor
- mesh/mesh2
- bicubic_patch

By specifying the `uv_vectors` in the triangles of a mesh, or optionally, in the bicubic_patch object, one gets exact control over what part of the texture is mapped to what triangle or patch.
