【Abstract】The track calculation of automobile steering process is very complicated. It needs
complicated math modeling with many formulas of Vehicle Dynamics. Automobile 3D virtual
system has high requirement for real-time, hence automobile steering model needs predigested,
meanwhile, the automobile track error must be controlled. Automobile 3D model is designed with
OpenGL; predigested track model is delivered by yaw rate estimation. 3D animation for
automobile steering is carried out. Experiment results show that both of the track and gesture
achieve favorable visualization effect.
【Key words】OpenGL; Automobile Steering; Track Model; 3D Model
