Where can I find some examples, tutorials or tips to apply a classic spherical environment mapping (or cubic) on a textured mesh in one pass? In the DX SDK sample, it uses Vertex Shader, but I have just arrived to apply this effect on a textured object by using two pass

. Thanks :: NeKo ::

The number of pass is the number of pass the graphic adapter will to to proper render things...

the more pass u have, less will be the framerate.

Example, if your card have 2 texts units(like geforce 2 mx) the graphic need to do 2 pass to blend 4 textures...

Hum, the meaning of "passes" wasn''t the real subject.
I think we lose the main point of my question.

If anybody has some information for me?
