Actually, any object that has an inside and outside, and a finite volume 
can be tesselated, for example by using the marching cubes or marching 
tetrahedrons algorithms. Warp's tesselation patch is an example of this.

However, the meshes don't use triangles very efficiently, and high 
amounts of detail require *huge* meshes.


PS: I think even shapes without an inside can be tesselated, as long as 
you can figure out if the surface is between any two points.
