I have created a small script that extracts the curvature values at many (u,v) points on a NURBS surface and writes them into a file. Essentially, it uses the functions rhinoscriptsyntax.SurfaceDomain and rhinoscriptsyntax.SurfaceCurvature.
I would like now to display a map of the curvature values in the Rhino graphical interface. I have no idea how to do that, but I suspect I can not do it at the level of a script and would have to go to a higher level. I would be very grateful if someone could give me a starting point where to start with this (I know python and C++).
