The problem is that I need to make quite a complex mathematical calculation (exponent) on a per-fragment level in hardware. If I’m not wrong, it’s possible with texture-shaders, where the result of the exponentiation can be put into a “lookup-texture”, but then you need atleast a geforce3. I wonder if it’s even possible to do this on a geforce256 or similar.
Thanx in advance for any replies!
