Nuke plot chromaticities script?

Does anyone please have a nuke script that plots (using pointsToPosions node) of:

  1. an input
  2. the spectral locus of a coulourspace
  3. the gamut bounds of a colourspace over a gamut graph i.e http://www.icsourse.com/uploads/allimg/101111/1_101111090145_1.jpg

Thanks!

Bump…

Anyone got one of these to share please?
