I have developed a rudimentary ray tracer on an APOLLO DN3500 (which incidentally has only 8 bit color capability). I have replaced the default (16 color) color map with a 256 color one. The RGB triplet that I get from my ray tracer is mapped into some arbitrary location in the color table which results in the pixel being illuminated with that color. The problem is with reflections and refractions. That is, the color of an object in my scene does not necessrily match the color of its reflection. This is because the RGB triplet returned for a pixel in the reflected object is different from the RGB of the original object and as such maps into a different location in the color table which corresponds to a totally different color (and not just a different shade of the original, as one might expect). This results in unnatural reflections and refractions. If anybody out there has ideas about what kind of a color map I should be using, I'll be glad to hear from you.
