Hi guys,

r OpenGL evaluators accelerated? I’ve heard that they are not?

Thanks

most GLU and GLUT specific stuff is not accelerated.

So how are they calculated?

If you mean glMap and glEvalMesh and related functions, these are part of GL and might be accelerated. Last time I tried, the GL evaluators was faster than my code somewhat well written code. Of course, it could have been because they (nVidia, ATI) use SSE and I didn’t.

I think that GLU’s NURBS use glEvalMesh and such as well.
