A Research of Optimizing Techniques for the 3D Scene Model Based on Creator

Most visual simulation systems are developed based on Vega. They are unable to make smooth operation because of large volume of data. In this paper, some key techniques about how to optimize the 3D scene model are proposed in order to improve the operating efficiency of the visual simulation system. Including simplifying the 3D model, cutting down the data stream of texture, techniques for creator modeling, setting LOD node, Optimizing the hierarchy structure of the database...etc., An experiment show that compared with the original system, the EMS memory of the optimized one is less, the data stream is smaller, and the time to load is shorter.
