How to extract generated mesh data from a Graphics3D object ?


Hi,

I am using Mathematica ver 6.0 and I need to extract generated mesh data from a drawn Graphics3D object like the way I do it with a Plot3D object as follows:

p = Plot3D[ Sin[x y], {x, 0, 4}, {y, 0, 4}]
p[[1, 1]] // FullForm (* this is OK and extracts actual generated mesh data *)

g = Graphics3D[ Sphere[{0, 0, 0},1] ]
g[[1, 1]] // FullForm (* ???? how is it possible to extract the actual generated data by Graphics3D ? *)
