OpenGL在虚拟现实技术中的应用研究

摘要

虚拟现实技术是当前计算机仿真技术的一个重要分支,是近年来计算机图形学领域热门研究方向。它在工业设计与制造、虚拟建筑、虚拟作战环境、影视广告制作以及娱乐等方面都发挥着重要作用。OpenGL作为开放式图形库具有强大的三维渲染能力,很多开发平台如Microsoft Visual C＋＋,都将OpenGL作为一个重要的模块扩展进来。介绍了OpenGL的定义、特点、原理,并采用两个例子来论证OpenGL在虚拟现实技术中的应用,给出了程序实现的流程。%Virtual reality is an important component of computer simulation,and plays an important role in the domain of industrial designing,commercial manufacture,virtual architecture,virtual combating environment,television advertising production,entertainment and so on.OpenGL,an open graphics language,has powerful ability in three-dimensional Render.Many software development platforms,such as Microsoft Visual C＋＋,extend it as an important module.This paper introduces the definition,characteristics,principle of OpenGL,and then applies OpenGL to two examples from virtual reality.The pseudocode is also presented.
