Interestingly enough, the existing gamma implementation seems to be mostly linear. Something like this:
Not sure whether this is directly better or worse than anything. From what I've read on the internet, using "pow" is considered the "standard" solution.
vec3 gamma[3];
slice(finish+2) {
bvec3 ishigh = greaterThan(color.rgb, vec3(0.5,0.5,0.5));
vec3 weight = 2.0 * abs(color.rgb - vec3(0.5,0.5,0.5));
color.rgb = (vec3(1.0,1.0,1.0) - weight) * gamma[1] +
weight * mix(gamma[0], gamma[2], ishigh);
}Not sure whether this is directly better or worse than anything. From what I've read on the internet, using "pow" is considered the "standard" solution.
