I think I don't understand you question.
Are you maping a 2d pixel map to a 3d triangle surface and want to know how to do it?

Basically, I want to map all the points in a texture map, to their
corresponding points in 3D space, given a standard 3D object of
arbitrary-sized polygons. Most of the time, the model is composed of
triangles and quadrangles, but sometimes there are polygons with more sides.
Does anyone have an idea on how this might be accomplished?
