The Design And Implementation Of Three-Dimension Animation Scene's Building Tool Based On VRML

In product design and manufacturing process, product show and preview, operation and training areas, three-dimension animation and simulation has a great advantage compared with transitional textual and simple image description ways. Three-dimension animation and simulation is easy to understand and receive. Now its demands are increasing and its uses are more and more widely. So it has great value to study and develop a three-dimension animation and simulation tool.On the base of introducing the purpose, significance of animation based on VRML, this paper summarized the related studies for application. Through analyzing the structure of VRML, the character of three-dimension models, the advantages and disadvantages of related developing tools and the demands of the system, I designed the structure of the system, found the way of searching and modifying the nodes of VRML files, found the method of catching models of the scene, described the collision detection algorithm of the scene, designed the process of implementation of scene animation and the methods of making sequence and anti-sequence animation by the path planning chain, implemented a prototype System, finally gave a application example.
