Wait only now did I realize that you need this only for boxes and not more complex 3D objects.
This actually makes things a lot easier because such box can be composed either from 6 individual images (each image for each box face) or one image representing extruded box which can then simply be projected onto the box for rendering.

So if I understood you correctly you are making a software tor designing these 3D boxes right?
