I was going over one of the tutorials at ultimagegameprogramming.com about display lists. Apparently they can be used to increase the performance of opengl for frequently used commands. Here is description from the tutorial.



Does Bmax utilize these? would it help the performance if it did?

Yes, you can use display lists - and yes, it will help with performance/fps.

But there is a down side.. its all precalculated at runtime, and locked away on the graphics card. This means you cant do any dynamic changes to the mesh. Fine for static objects.. no good for animations or editing vertexes directly.

Use a mixture of Display Lists and Vertex Buffers. (you'll find posts of my questions for vertex buffers on here somewhere)
