How to Trim Triangulations

Question: How do I prevent the triangulation feature from spanning concave regions of my plot with triangles? Solution: Extracted polylines can be used as boundary zones to limit the triangulation. In particular, these polylines can be used to prevent triangles from spanning concave regions during 2D triangulations. The following procedure utilizes these polylines to trim a triangulation of unorganized data to the desired shape: 1) Load the data to be […]
