WebOct 3, 2024 · The Delaunay triangulation method is tedious and difficult to converge. The greedy algorithm does not consider the overall situation, and it only seeks the local optimal solution [16,17,18]. Therefore, in the point cloud fitting, the greedy algorithm is considered a local fitting method. http://gamma.cs.unc.edu/SEIDEL/
