I am once again projecting the sRGB gamut into xyY space. This time, 
however, I am generating a mesh parametrically instead of creating an 
isosurface.

All goes well until R, G and B are all equal to zero, since xyY space 
doesn't like this coordinate.

How should I handle this case? Should I just skip it and not render a 
triangle there? Or is there a better way to handle it?

Thanks!


Mike
