Dithering ninjas +Rolf W. Rasmussen and +Florian Rivoal: I'm generating images with 24 bits per color channel, and the screen representation (at 8 bits per channel) shows banding in gradients. The best result so far has been to round up or down semi-randomly to the nearest 8 bit color (depending on the fractional part), as shown in the link below. Any tips for improvements? Will a fixed pattern look better? Bonus: Can I do this while keeping the gamma correct (preferably efficiently on the GPU)?
