纹理映射在模型优化中的应用

三维模型的构建是虚拟现实及视景仿真系统中最基本、最重要的组成部分之一。构建三维模型需考虑到场景浏览的真实感与实时性,因而需要建立一个最优化的可视化模型。本文比较了在虚拟现实系统中模型优化的方法,采用了纹理映射代替多边形建模创建高效真实感模型的优化手段,着重介绍了颜色纹理和凹凸纹理的相关理论和方法,并应用于视景仿真系统中,极大的提高了实时性,并保证了真实感。

The simplification research of 3D Model by texture mapping

3D model is a fundamental part in a virtual reality system. Constructs the three- dimensional model to have to consider to scenethird dimension and real time, thus needs to establish an optimized visibility model. This article has compared in the virtual reality systemcenter form optimization method, used the texture mapping to replace the polygon modelling to found the highly effective third dimensionmodel the optimized method,Introduced emphatically the color texture and the bump mapping texture related theory and the method, and us-ing in the ground view simulation system, enormous enhancement real time, and have guaranteed third dimension.
