汽车驾驶模拟器中3D场景的设计和实现

Design and Implementation of 3-D Scene in a Drive Training Simulator

1 引言汽车驾驶模拟器是一种能正确模拟汽车驾驶操作,并能在主要性能上获得与实车相同感觉的汽车驾驶训练仿真教学设备。一个好的模拟器应该有一个立体感强、图形逼真的三维视景。YF三维汽车驾驶模拟器的视景系统采用计算机实时生成技术(称为CIG视景系统),它根据当前汽车的状态实时生成逼真的三维场景,使学员感觉就象驾驶真的汽车一样。

Driver Training Simulator is a driver training facility. Driving the Driver Training Simulator has the same training effects as driving a real car on a real road. 3-D Scene System is an important subsystem in the simulator. In this paper, the design and implementation of the 3-D Scene System is presented.
