I'm having trouble with banding when making grayscale gradients - ie. I seem to be getting discrete jumps in shade that seem too big when compared with a similar gradient in Photoshop. I've tried using colorsquare and blending between vertices using GEMglColor4f. Has anyone got any tips?
IS the color bit depth set by the hardware/can I find out whether things are working at 16bit or 32bit?
I'm running a MacBookPro with an Nvidia GT330M video card with GEM 0.92.3.
