This definition creates volumes from points

LOGIC

1. Create a set of points in 3D space
2. Approximate a sphere that encloses the entire point collection
3. Convert the sphere to a mesh
4. Find the closest points in the point collection to the sphere
5. rebuild the sphere mesh with the closest point collection points
6. remove unused faces and points

Tip

If points are co-planar a surface will be created rather than a volume.
After the volume is made try the process again. This time take the
volume, subdivide it with weaverbird, then use that volume in the same definition 
to take the spheres place. This will make more refinement. You can then
iterate the process with hoopsnake. Use weaverbird to smooth the mesh and 
get some nice freeform shapes. Try using mesh UV instead of mesh brep for
more control over the amount of points on the sphere or change the mesh settings.
Also, try using other mesh shapes besides a sphere as the bounding volume.
