I am programming textured mountains on which one can walk, and now I need to optimize them :
1. Would backface culling help ? If yes, how to activate it ? (I didn't manage to do it).
2. How to use vertex arrays ? Is there any tutorial ?
3. Would NURBS be faster ?
I need your help !
Re: Optimizing Mountains
1. Yes. glEnable(GL_CULL_FACE)
2. Yes, particularly if combined with glDrawElements. Also consider using diaply lists. See http://nehe.gamedev.net/
