[Fluxus] collada

[Dave Griffiths]

Hi all,

It's WIP at the moment, but I've begun to add collada[1] support to
fluxus. The idea is that you'll be able to build scenes in (eg.) blender
and import them wholesale into fluxus. The lights, cameras and models in
the scene will be accessible to your scripts as normal fluxus
primitives. 

The longterm goal is to import skinning information and animation clip
data, for characters being driven by scheme code.

Currently the geometry importer works for triangulated topologies, and
imports vertex positions, normals and texture coordinates. The main
thing I have left to do is to re-index the model where there are
seperate indices for vertex positions and other data - basically it
won't look right for some kinds of models right now. (Seems to work for
ducks though [2]).

cheers,

dave
