| 摘 要： | 在VRML虚拟环境中，运动对象在曲面上的姿态调整是提高虚拟现实水平必须克服的难题之一。文章提出了一种基于支撑平面计算车辆姿态参数，随三维地形的起伏自动调节其运动姿态，并进行三维显示的算法。描述了具体的算法设计，讨论了算法实现的关键技术，并应用于某履带式电传动车辆的虚拟现实仿真中。运行结果表明该算法实时性好、运行稳定可靠，逼真表现了运动车辆的动态行为过程。

| Abstract: | To improve the level of virtual reality system, adjusting attitude of mobile to accord with curved surface is an issue to overcome in virtual environment based on VRML. A design of calculating parameters on vehicle attitude based on the support surface, and adjusting attitude automatically with the three-dimensional hypsography is presented. Algorithm is described in detail, and key techniques are discussed, and the design is applied to the virtual reality simulation of electric drive tracked vehicle, The simulation based on the algorithmic can run steadily and reliably in real-time, and show dynamic behavior of the mobile vehicle realistically. |
