Marching triangles would be an ideal general method, but quite a bit 
more difficult to implement. I'll look into it, but I'm mainly focusing 
on the object-specific tessellations, I planned to incorporate one of 
the existing general tessellation patches. Marching tetrahedrons seems 
to give fairly good results without any patent issues. The main reason 
I'm writing this patch is so I can get meshes of arbitrary objects for 
improved proximity pattern, curvature pattern, and glow patches.
