Hello, i have a point cloud in Matlab and want to plot the surface of it with delaunayTriangulation. The problem is that the triangulation always returns a "body", meaning a convex hull. But my point cloud is only a part of a convex body. Is it possible to make the triangulation stop at sharp edges? I added exemplary pictures with the current surface and the surface how i want it to be.
Thanks

Is your surface a structured or unstructured grid? How you have the data?

No, it is not possible to have that kind of triangulation stop at sharp boundaries. That kind of triangulation is not appropriate for finding surfaces embedded in a 3d point cloud.
