The technology of virtual prototyping (VP) is finding increasing applications in the field of bodywork design. This research applies image-based 3D reconstruction technologies to create an easy to use and vision-rich virtual prototyping system of the bodywork. First, the principles for image-based 3D spherical reconstruction with image mosaics technologies are illustrated based on the analysis of the process of image formation. Second, the matrixes and equations employed to implement spherical texture mapping are proposed. Third, the programming method to realize image-based 3D spherical reconstruction is represented. The final product is a virtual prototyping system with novel mapping algorithms for automobile design. This system enables designers to modify the design according to the user real time feedback. It could improve the design efficiency greatly.
