A quick question :
Is TRUE layered fog (i.e. not with horizontal textured quads) something we can achieve only through high end cards (GeForce3 and above, Radeon …) thanks to their “vendor added extensions” ? I need to implement such a fog effect for a flight sim, but the only fog I can produce with my GeForce 1 is “distance-from-point-of-view” based, thus making It hard to get the fog layered…
Should it be the case, do you know any good example of layered fog with textured quads ?
Thanks
