Abstract
A method for mapping a two-dimensional image of a physical object onto a computer generated three-dimensional surface defined by a plurality of surface points in a CAD space has the steps of creating a two-dimensional texture image plane of the physical object by taking a photograph of the physical object with a photographic device and converting the photograph into a texture image plane having a plurality of texture image plane points, determining a physical position of the photographic device with respect to the physical object, and transferring the texture image plane onto the three-dimensional surface. The transfer is accomplished by positioning a synthetic camera in the CAD space with respect to the three-dimensional surface according to the physical position of the photographic device, mapping each of the plurality of surface points viewable by the synthetic camera to a corresponding texture image point in the texture image plane, and assigning texture coordinates to each of the plurality of surface points from the corresponding texture image plane point.
