: : Interesting...did you try textured objects? If yes, are the textures stable under animation?

: Yes, I implemented texture coords. But animation of the base mesh vertices is not yet possible in my work. I want to try that when my master thesis is finished.
: For the moment I can't imagine, why textures should not be stable. As long as the coords. in the base mesh don't change, nothing should go wrong.

The reason I think textures may not be stable is that, as you traverse from one LOD to another your base mesh expands/contracts so you need to do a texture-object coordinate association in real time. I did this for tensor product surfaces (I can send you my paper) and it proved to be real difficult. I think that tensor product surfaces are easy compared to subdivision surfaces. If you want to talk directly my email address is egas@pacbell.net.
