摘　　要：探讨视景系统开发中的若干模拟特效,如粒子特效(如雾、雨、雪)的仿真、声音效果、GPS仪表指示器,及基于全局光照的烘焙渲染等技术.基于Cg的Shader多分辨纹理技术采用GPU硬件绘制方式,改进了传统的Mipmaping算法,提供了一种快速的实时绘制方法.这些技术增强了驾驶模拟器视景仿真系统的可视化效果.The special effects in visual system are discussed in this paper, including simulation of the particle effect （fog, rain and snow）, sound effect, GPS, instrument panel simulation, rending technologies of baking based on global illumination, etc. With application of hardware rendering technology based on programmable GPU （Graphics Processing Unit）, shader technique of multi-resolution texture on Cg provides fast real time rendering, and improves algorithm of traditional mipmaping. These can be used to improve the visual effects in the visual system of the driving simulator.
