I have an openGL circle which is a fan of triangles. The colors at each
point on the circle run around the spectrum in hue, so it is like a big
Now, because of the way openGL interpolates the colors, the color range does
not look the way I want. For example, there's a lot more green than yellow,
and hardly any orange.
I was just wondering if there is a simple kind of equation that would let me
choose a few points on this range and "pump" them up, or maybe choose others
to "pinch" so that they take up less room on the wheel.
Maybe just a bunch of if then statements which re-scale specific value using
a simple x*x curve or something -- but I thought I would ask to see if
someone had a better idea.
