    Nebulae, part III

    Would it be possible to see a picture with only the "emission" coloring and another with only the reflection coloring? I am curious about the influence each has on the final render. Also could you detail the workings of the lookups for the speed and angle? Is speed simply = previous - current? Is it normalized in some fashion? Is the angle = acos( normalize( previous - current ) DOT normalize( next - current )? What do the lookup tables look like? I apologize for the abundance of questions; the technical details here really interest me.
