摘要
三维模型是虚拟现实系统中重要的组成部分 ,在三维模型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 ;二是即使是在高性能的PC机上 ,浏览场景也是一件繁重而费时的事。当鼠标移动之后 ,场景变换要滞后几秒钟甚至几分钟。为此需要对模型进行优化 ,该文从简化模型和提高渲染速度两个方面介绍了基于Creator的优化三维模型及减少载入时间的几种方法。
D model is a primary part in a virtual reality system. There are two main questions in the process of using the models. One questionis that it expends much time in loading a scene and the other is that it is hard to look through it. There is a apparently delay for the scene changing when the mouse is moved. So it is necessary to optimize the model. The article introduces several methods to optimize and simplify 3D model so as to quicken load and romance based on Creator software.
