3d Animation And Motion Simulation Technology

CAD(Computer Aided Design) technology has developed rapidly and been widely applied since its appearance in 1950s. It expends to 3D sculpting from plotting and already becomes indispensable auxiliary tool of various industries.Since traditional product design commonly signifies mechanical parts and their assembly relations by ichnography and shows machine at a settled position. It's not only difficult to describe the movement state of parts and their ubieties when they are working but also incapable to directly determine whether the movement is reasonable and the interposition occurs or not. This problem will be resolved effectively when 3D sculpting and computer animation technology begin to be applied to 3D entity movement simulation.In this paper, 3D entity animation technology has been researched. It is designed with object-oriented method based on 3D modeling software-JHSolid. This paper discusses how to implement 3D rotating animation, exploded animation, retracting exploded animation and framework working simulation animation of 3D assembly entities based on product assembly models with double buffers technology, matrix transform and display list of OpenGL and also realize video capturing of animation process and recording the video capture result as an AVI file.It has verified that this program has succeeded in realizing above-mentioned functions, which prove the correctness and feasibility of this method.
