How does it work? What algorithm is it using? Chances of seeing on non OpenGL platforms?
It loads a dither matrix generated with https://git.fruit.je/src?a=blob;f=dither...26;hb=HEAD
into a texture unit. Finally a shaders uses this matrix to generate noise and cure banding effects when transforming from limited to full range color space.
Ok, thanks for your answer. From the little I understand I think there's nothing serious stopping a non OpenGL implementation (for Windows, basically). Thanks again.
I don't think so either. It's no rocket science.
