基于Creator的汽车试验场的建立

Construction of Automotive Proving Ground Based on Creator

基于虚拟现实技术开发的汽车仿真试验场具有真实、廉价、实用性强等特点。文中详细介绍了使用Creator软件构建汽车试验场的过程和方法,论述了高质量场景的建模技术,对场景的地形构造、纹理制作及映射、道路模型的构造等建模技术进行了探讨。提出了场景数据的优化显示技术和场景模型简化方法,提高了场景模型在仿真运行过程中的实时效率。最后给出了汽车仿真试验场建模的实例,并探讨建模过程中应注意的问题。

Simulative automotive proving ground has the characteristics of reality, low cost and practicability. In this paper, the procedure and method for constructing the automotive proving ground based on Multigen Creator are introduced in detail. The modelling technique of high - quality scene has been discussed. It also expounds the modelling technique of the terrain generation of scene, the edit and mapping of texture, the creation of road model, etc. Some techniques and methods for optimizing the scene database and simplifying the scene model are also proposed to improve the real - time quality of the simulation on the scene model. Finally, an example of constructing the automotive proving ground is given, and some problems to be noticed in the modeling are discussed.
