what if the point cloud represents a 3D object rather than just a surface? how should i go about it to convert the outer points into a surface?

i've been stuck with this problem for a long time. the only close enugh solution i've found is 'tetramesh' but its a very bad and slow one.

If you have a filled colud there are two main options, depending if your cloud comes from a tetraedral FEM mesh or not.

-If you have tetraedrons, than it is easy just get the boundary triangles.

-If you do not have them, it is more complicated, a ball pivoting or alpha shape tool is needed.
