How do you generate an open mesh from points like this...

Unity Engine

I have tried using convex hull, but that only creates closed meshes, and also tried using delaunay triangulation, but the solutions I’ve found are only 2D.

I have all the points data, I just cant find the right meshing algorithm.

Any ideas what kind of triangulation this example is using?

I think maybe marching cubes? Ask the twitter poster, most people will respond.
