摘　　要：随着计算机软、硬件性能的不断提高和优化,在实时三维视景仿真中,光照效果已经成为一个越来越受到人们关注的特效,光照效果的好坏已经成为影响视景仿真逼真程度的重要部分。该文就是以VisualC++6.0为开发平台,使用基于OpenGL的三维视景引擎OpenGVS4.3模拟出夜间光照效果,提高三维视景仿真的逼真度。该文所实现的光照效果分为静态光照效果和动态光照效果,静态光照主要用于场景中固定光源的照明方面,动态光照效果采用位置同步和方向同步算法模拟车辆大灯、机载探照灯等运动物体上光源的照射效果。With the advance and optimization of the computer hardware and software, illumination effect has become a focus in 3D game special effects. Illumination effect can in great extent affect the simulation reality. The article bases on Visual C ＋ ＋ 6.0 platform and employs 3D engine-OpenGVS V4.3 to create lighting at night and this improves the fidelity of 3D world visual system. Lighting effect in this article can be sorted into two types, static lighting and dynamic lighting. Static lighting refers to a fitted lighting source and dynamic lighting uses Position-In-Phase and Direction-In-Phase arithmetic to create effect of lighting which is equipped on moving objects, such as vehicle headlight, vehicle carried searchlight etc.
