Agisoft photoscan is a software program able to build a 3D reconstruction of an object using photos. A very interesting tool for 3D and fashion designers, architects and artists.
The reconstruction requires images taken from all sides of the object, including close-ups. In a few steps, photo alignment, mesh construction and texture map generation a 3D model can be exported for use in 3D programs or PDF reader.
Below is an example of the 3D reconstruction proces of a little cave in the park of Leuven:
