Meet the GIMP #74: Wrap 10, Philippe!
Philippe takes a forum thread about “texture wrapping” and turns it into a tutorial. During the process he got a real nice tree bark.
With texture wrapping you can give a flat texture the look of being on the surface of a 3-dimensional body. This is the domain of Raytracers and 3D programs like Blender. But for that you need a mathematical model of the body in question. This is not available in photographies.The TOC
