Would u happen to know how to triangulate the points in a way inside the polylines to look something like this ? I sadly am not familiar with mesh triangulations or how to convert the surface to a mesh and triangulate it afterwards.
This is a very good start for me to work with. However the beauty of the other drawing is that the triangles don’t only span from the corner points, but there are extra points that gets created inside the surface that helps to create extra triangles. Will try to work with this one and add more to it.
