使用OpenGL开发实时三维应用程序

Developing Real Time 3D Applications with OpenGL

计算机三维图形技术已发展到了实时阶段 ,怎样有效地开发实时三维应用系统 ,是目前较为引人注目的话题。笔者先后开发了数个OpenGL三维应用软件 ,从中总结出了实现实时三维应用系统的不少关键技术 ,包括实用的初始手段、分类分批建模、纹理、实时用户浏览控制及其位置处理等。这些技术已应用于实时电视特效播出系统、道路可视化设计 /评价系统等。笔者将开发中总结的典型作法与经验作一个方法性概述。

D computer graphics technology has progressed to the real time stage. One of the most attracting topics today is how to effectively develop real time 3D systems. The author of this paper has experienced developing some OpenGL based application softwares, and has summarized lots of key techniques including initializing methods, modeling in classes and groups, textures usage, real time viewing control by users and viewing position processing. All these are successfully adapted in the implementation of such systems as real time special effect TV title system and visual road design and evaluation system. In order to be a reference to other researchers and developers, and to make progress together with our competitors, a methodical description is presented here to summarize some typical steps, methods and some valuable experiences.
