once more I'd like to know some opinions of you advanced gl-people, to avoid spending too much time in doing stupid things.
I'd like to build a terrain for a 3D-game, and I heard several times about height-maps to do that. But in my gl-Book (superbible) I didn't find sth. about that, but about bezier-surfaces and nurbs. So I built some beatiful bezier surfaces with lots of control-points and texture, and now I'd like to know if there is a reason to prefer height-maps (whatever they are).
I've just had a problem with these bezier-surfaces, but I dont know If it's because of them or because of my glBlendFunc: I could not put a blended quad under the surface to make some water (in the regions of the surface that are lower than this blended quad).
However, thanks for opinions and tips!
