Mesh Deformation Driven By Image And Its Application In Automotive Design

With the rapid development and wide application of computer science, mesh deformation has become a powerful tool in the fields of computer aided geometry design (CAGD) and computer graphics (CG). Many mesh deformation schemes have been proposed in the recent three decades, especially the space deformation. It has more reality, less interface and it is important in domain of simulation of polygonal mesh modeling.In this paper, we propose an image-driven 3D modeling technique for rapid panel design. Our semiautomatic approach is based on template technique and mesh volume deformation controlled by a special cage. We designed our modeling system to be interactive in 2D, automating the process of shape generation while relying on the user to provide image samples. Once a parametric model template is given, using the contour extracted from images, the new control cage corresponding to mesh models generated. Then the geometry of new panel is automatically recovered from the deformable template model. Our system also allows the user to easily reconstruct other 3D objects in a similar manner, such as realistic looking plant modeling from images. We show realistic reconstructions of a variety of panels, automobile shapes.In this paper, we give the result of the experiments, which indicate that we able to achieve the purpose, and get reality effect. Therefore, this technique will have good application foreground in animation for games and films, polygonal mesh modeling and so on.
