View Full Version : noise in opengl



04-05-2005, 03:35 AM
i tought that appling noise to any opengl scene is very simple - just generate noise texture, apply it on a cube and show on screen with blending. i was wrong. i try to make it for about 4 days and nothing, but errors (windows) :) . have you know about any simple examples of appling noise to opengl window? i`ll appreciate any help.

what do you mind? tutorials, articles, or forum?
i saw, that nobody has written any art or tut about it, and for now nobody asked about it on forum.. maybe it`s too simple?

You don't even say what your problems are...
The method you described is the way, in fact it is just classic texturing with blending and a noisy texture.
Each of theses steps (but the noise) is described in the nehe tutorials.
