Abstract: Real-time moving vehicle modeling and dynamic behavior simulation is an important research in virtual reality game engine. In this paper, a real-time vehicle game engine was designed and presented. Auther provided a method of real-time vehicle rendering based-on multi-body dynamics in engine, and could simulate different of dynamic behaviors as real as in real world. The other techniques such as collision detection, 3D music rendering, real-time virtual environment rendering were also realized. Thus,it can enhance the immersion when user walk-through virtual environment.

Key words: irtual environment, game engine, real-time vehicle simulation, multi-body dynamic, collision detection

摘要： 运动车辆的实时建模、动力学行为仿真是赛车虚拟环境中的重要组成部分。论文设计并实现了一实时赛车游戏引擎,在引擎车辆建模中提出了一种基于多体动力学理论实时逼真的赛车建模方法,对赛车的真实受力状况进行简化,模拟车辆的各种动力学行为和车辆运动的真实感绘制。并实现了引擎中的碰撞检测技术、音效处理技术、虚拟环境的实时绘制技术。增强用户漫游虚拟环境的沉浸感。
