Constraint-based solid modeling is the kernel part of current CADsystems. It has been widely used in supporting detailed design and variational design. However, it cannot support early stage design and is not easy-to--use becauseit demands fully detailed input description of a design. To solve these problems,researchers attempt to incorporate virtual reality techniques into geometric modeling systems. This paper presents a novel approach for interactive constraint-basedsolid modeling in a virtual reality en…

Key words: AVS; discrete cosine transform (DCT); integer transform; quantization;
