C3D is a GUI-based computer program that converts the implicit 3 D information contained within the stereo image pair into an explicit 3 D surface model in a standard CAD file format. Hence, C3D extracts automatically the 3 D information from a stereo pair of images which have been frame-grabbed (digitised) into a computer and then builds a 3 D surface model. This surface model can then be edited using standard CAD packages or manipulated within virtual reality environments in the usual way. </ABSTRACT></RECORD></RECORDS></XML>
