In order to get a true 3D and textural representation of a complete head or face, one really needs to consider more than one or two representative angles (at this level of consideration).  The best situation would be about five representations: frontal, left side, right side, top, and bottom.  Then the coordination of these representations should be very (or ideally) accurate.  It would be possible to achieve nearly satisfactory results with disjoint (non-orthogonal) angles if the software could handle more disparate image angle representations.  But even ImageModeler really doesn't present that level of accuracy without well-thoughtout, careful preparation and execution.

Suffice it to say, that level of 2D-3D topological conversion isn't at the level for most of us to afford.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
