A filter for an icosahedral color wheel. I need to create the RGB values and then tell Paraview to visualize it similar to the way Generate IPF Colors does. I will basically define 12 patches on the unit sphere and then figure out which of the 12 the c axis of each pixel hits and color accordingly. Based on Yamrom's method:

Yamrom B (1997) Method of color coding orientation information.

Utility patents survive 20 years, so it is no longer protected.

I have some old C code for this, which I am working towards porting into DREAM.3D as a new filter.
