| Abstract: | Optimization and reconstruction of VRML models in web-based virtual assembly is researched. An information model of five hierarchies in virtual assembly is proposed firstly. Then, the syntax structure and parsing process of VRML models are analyzed, and a node reconstruction algorithm and an optimization algorithm are established. By using the algorithms, information representation and organization structure of VRML models are optimized and reconstructed, and well meet the requirements of quick design and analysis in virtual assembly. A prototype system of web-based interactive virtual assembly is developed and the algorithms are verified. |
