I am working on a delaunay-based algorithim which I would like to apply on 3D geometry -> paramertic surface (nurbs surface in rhino). The surface has no “overlaps”, thus it can be projected to cplane without self intersection. I thought I could simply map the uv-coords to xy space in order to solve the entire thing in 2D. I don’t know how to do this best. The first approach I tested is based on this gh thread:
But this simple mapping does not do the job. The distances of the points on the surface do not correspond proportionally to the distances in 2d on the xy-plane. Rebuilding the surface seems to help a little but I still think I am not getting the right result. Is there another way to do this? Maybe with some sort of transformation matrix I could generate from the surface information.
