摘　　要：针对传统虚拟漫游系统存在的沉浸感差、交互差等缺陷,提出了一种基于OpenGL技术开发交互式三维虚拟漫游系统的方法。以三维图形理论为基础,基于OpenGL技术和编程工具VC++开发了一个交互式虚拟漫游系统,并详细讨论了交互式场景漫游的一些关键技术,如场景的建模,烟雾的模拟,地面天空的绘制,交互控制,视点漫游技术的实现,等等。实验结果表明,交互式虚拟漫游系统实现了三维虚拟场景的漫游交互功能以及部分自然现象及景观的模拟,取得了良好的仿真效果。In view of defects of poor immersion and interaction for traditional virtual roaming system, we present a method of developing in- teractive 3D roaming system based on OpenGL. On the basis of the three-dimensional graphics theory, we develop an interactive virtual roa- ming system by means of OpenGL technology and programming tools VC＋＋ and discuss some key technologies of interactive scene roaming in detail,such as the modeling of scene,the simulation of smoke,the drawing of the ground sky ,the interaction control,the realization of viewpoint roaming and so on. Experiment shows that the system designed can realize the roaming interaction function of 3D virtual scene and some natural phenomena and landscape simulation, with better simulation results.
