基于OpenGL的山体模型算法及其可视化

Algorithm and visualization of a mountain model based on OpenGL

根据一种常见的山体形态,利用OpenGL基本图元构造了一种可控、易扩展的山体模型算法,并结合Open-GL的颜色渲染、纹理映射和光照处理等真实感技术,实现了从单个山体到山体群的形态可视化,为模型的应用奠定了基础。试验结果表明,该模型简单易用,扩展性强,可用于实时渲染的CAD建模系统及其它三维场景建模系统中。

This article constructs a manageable and expandable mountain model algorithm by making use of a graphic primitive of OpenGL and brings about visualization of mountain from single mountain to many mountains combined with color rendering, texture mapping and light processing. The model not only can render a common mountain,but also can be used as the one that is similar to mountain, such as stalactites and mountain slope. Besides, this model in application can be used in real-time rendering CAD modeling system and other three-dimensional scene modeling system.
