Appearance applied at the wrong level #3

Currently, Appearances are applied to whole Geoms! For example, there is no way to apply different Materials to different Faces in a Trimesh. A Trimesh should be made of Faces and Appearances should be applied to Faces.

The obvious problem is efficiency! If each Face is a separate object then Spook would require a lot of memory to hold a Trimesh! I should change Trimesh to use indices, then every triple index would be a face. Then each Appearance could be given a range of faces (a list of shorts representing the face indices) to be applied to.

This may not be a problem. Models that specify different appearances for different parts can be broken down into several nodes each with extensions to the root appearance.
