WebNov 23, 2024 · If the raycast hits the wall, use a Polygon Clipper Library ( Clipper in my case) to cut out that part of the mesh. Use the vertices returned from Clipper and feed it into a triangulation algorithm. Use the triangles returned from the triangulation algorithm, and the vertices from Clipper, to construct a mesh, along with its normals and UVs. WebEar cutting (or ear clipping) applies constrained triangulation by successively 'cutting' triangles from a polygon defined by path/s.

WebApr 4, 2014 · There is a simple Ear Clipping algoritm which has complexity O (n^2) And there is constrained Delaunay algoritm which has complexity O (n * log n) So the question is. Is Delaunay algoritm faster than Ear Clipping? I ask, because I understand, that if n time is significantly bigger for Delaunay, it may be slower after all.
