虚拟环境中运动车辆行为仿真的程序方法研究
Procedural Method for Attitude Simulation of Moving Vehicles in Virtual Environment
摘要
Abstract
The visual simulation technology is of great significance to describe the virtual environment, and the moving attitude dynamic display technique of 3D virtual objects is a key technique. This paper studies the attitude realistic display technology of a running vehicle in the virtual environment with a natural undulating terrain. With varying local conditions of the terrain, the vehicle attitude shows a corresponding change because of the effect of gravity. An algorithm is designed for computing the attitude display parameters according to the body support plane of the vehicle defined by the lowest point of its wheels. The paper presents the process of the algorithm, and provides a detailal discussion on some important techniques. The algorithm is suitable for the vehicles with different number of wheels as well as tracklayer, etc. , and only a reasonable support plane is to be defined.The simulational result shows the highly realistic effect.关键词
