I’d like to know if there is a way to evaluate a point on a surface for the color that the Rhino viewport is displaying. Basically, I’d like to find all points on a surface that are being rendered in the viewport within a specific range. Is this possible? I have tried looking for commands in Rhino Commons that would allow me to get some basic information about the render material, type, etc. as well as being able to use the surface commands to evaluate the surface, but i’m having a hard time finding something that could tell me the color at a specific point on the surface.
