From edge bundling / wooly paths to surface between

Thanks for the tip and the good exercice. I took a look to this problem, I used mesh instead of surface, so faces acts like pixels, I made a little C# in order to have the difference between two subsets. The list of face number (0 to n-1) and the list of faces intersecting the curves. All others component must be legacy Rhino. It tooks 15 s with 32 000 points, length of 1 15 s with 120 000 points, length of 1 105 s with 962 000 points, length of 0.5 [image] [image] [image] If you want …
