Compute vertex colors in grasshopper

Thanks for the hints.

But if you program a bit it is not difficult to get the UV coordinates.

Copilot wrote the python script. I modified it a bit and it works:

import rhinoscriptsyntax as rs
import Rhino

def extract_uv_points(mesh):
    if not rs.IsMesh(mesh):
        return []

    uv_points = []
    for i in range(mesh.Vertices.Count):
        uv = mesh.TextureCoordinates[i]
        uv_points.append(Rhino.Geometry.Point3d(uv.X, uv.Y, 0))
    
    return uv_points

uv_points = extract_uv_points(mesh)

Wait Rhino 9 has a component called ‘Texture Evaluator’
