stonemason is basically correct, actually. I own RealViz's ImageModeler (v3.5) and it takes a lot of work and careful preparation to turn a set of photographs into a reasonable 3D model (textured or not). And if the model isn't reasonable, the textures will not be either. You need a good set of photographs - various angles, same camera properties, same distance if possible, good lighting. Then you need to correlate points between them in a way that captures the shape. ImageModeler was a ba$-turd to get the calculation to work properly even with 8 or 16 images and dozens of correlated control points. You can get a good detail in both the model and texture, but it really requires some work. Unless you really need photogrammetry for some reason, it is almost always easier to model the object yourself. Texturing can be fun to go from photo to flat for UV mapping, but it can be done. Maybe the guys over at BBC have better software - there is some better photogrammetry software out there - if you have $5K to $15K to splurge! ;)

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