Vector graphics have no advantage over bitmap graphics in this
situation.  Just export a high-resolution PNG from Mathematica, and use
that.  For any 3D object of reasonable complexity, there will be no
significant differences in file size.

But vector formats do have disadvantages: 3D objects with transparency, 
exported as PDF, look awful in most (not all) PDF viewers:
