Shaders

Occasional releases of GLSL shaders that I’ve developed for the Max/Jitter environment.

Colorspace conversion

Translation to/from RGB into a variety of perceptual colorspaces.  I developed these as part of a palette derivation tool for arbitrary images, release forthcoming.  All algorithms adapted from those at the EasyRGB website.  Transforms to/from the CIE-XYZ color space assume a 2º Standard Observer, D65 illuminant.
