As I’m developing my own viz tools to see hundreds of thousands of color points for my thesis, I’m going to quickly whip up some tools in Blender (why not give it a try?) and in Python (so quick…)
The biggest problem will be normalizing my high dynamic range (HDR) data into normalized 8 bit-per-channel color ranges (LDR) without getting rid of my initial data.
