If the point cloud closely describes the entire volume of the shape, then Marching Cubes might work for you.

This article will help you get started:

If you have any questions, please reply.

Here are some surfaces reconstructed from point clouds using Marching Cubes:

Hey think what your lookin for is a Delaunay Triangulation algorithm, do a search on google theres loads of sites, i had to look into it for rendering a 3D object from a set of points generated from a set of 2D images.

A guy in research for microsoft has done a lot of work in this area...
His name is something like Hugh Hoppes (search it on Google)
I believe there were a number of papers with his work. Check it out, that and his other work is rather impressive.
