基于Creator的三维场景优化技术的应用

高质量的三维场景是虚拟现实系统中重要的组成部分，在三维场景的处理中存在两个主要问题：一是载入场景文件要花费很多时间；二是即使在高性能的PC机上，浏览场景也是一件繁重而费时的事情。在三维场景数据未优化状态下，较大规模的场景变换通常会滞后几秒钟甚至几分钟。本文从算法、建模和渲染速度三个方面改进了几种场景数据优化技术，在应用中取得理想的效果。

The Application of Optimizing Techniques of 3d Scene Based on Creator

High-quality 3D scene is a primary part in a virtual system, There are two main questions in the process of using the 3D scene. One question that it expends much time in loading a scene and the other is that it is hard to look through it on the highperformance PC. Before the 3D scene is optimized, there is a apparently delay for several seconds or even minutes in the more larger-scale scene changing. The article improves several techniques which are got from algorithm, modeling and rendering speed to optimize 3D scene and net ideal effect in application.
