PROBLEM I want more people in my scenes rendering at 60 Hz. INVESTIGATION
1. Well I spent all this time putting in LODs, but I didn't get spectacular results. :( I render a man model, and looked at the stats. High level LOD 3497 vertices 0.5 Draw time Low level LOD 805 vertices 1.0 Draw time The draw time is the draw time of the actual model (I cancelled out the 0.5 draw time of drawing nothing) 2. Stopping his animation doesn't improve the stats. 3. Removing the textures doesn't improve the stats. 4. Rendering a non-cal3d model of 4837 vertices gives me 0.25 draw time. 5. If I tell the geometry of the rbody Submesh to setSupportsDisplayList(true), the man no longer animates, but the draw time goes to 0.2. QUESTIONS 1. Where is all the draw time being spent for cal3d/rbody? 2. What can I do to reduce the draw time? 3. Any suggestions on how to find the performance bottleneck? For now, I'll continue to hack away. Thank you.

I have also a similar waiting project there - to finish a BVH skeleton and animation loader for Blender. There are some really nasty and non-trivial issues there so I cannot blame you for the Cal3D one - I have seen the code when I needed a converter for our in-house animation format to Cal3D and it is certainly not a piece of cake.
