Hi, I published a new hip that implements “Exact Evaluation Of Catmull-Clark Subdivision Surfaces At Arbitrary Parameter Values”😀 It computes the position and tangent plane after applying Catmull-Clark Subdivision from any position on a polygon.
I might implement application to boundary polygons someday😅
