基于虚拟现实的拖拉机试验场景建模技术研究

介绍了使用三维建模软件Multigen Creator创建拖拉机试验场的建模过程和方法;探讨了场景模型数据库的结构设置、地形构造、地物模型建立、纹理映射以及其他关键建模技术和难点,详细阐述了试验场典型试验路面的建立过程,建立了一个适用于虚拟现实系统的拖拉机虚拟试验测试场景。通过测试,场景模型在Multigen Vega Prime仿真过程中内存占用较小,实时运行效率高,为进行拖拉机虚拟试验检测提供了新方法和场景平台。

Construction of Proving Ground for Tractor Based on Virtual Reality

The procedure and method for constructing the proving ground based on Multigen Creator are explained in detail.The modeling technique of high-quality scene has been discussed.It also expounds the modeling technique of the terrain and cultural feature generation,the edit of texture,the creation of road model etc.Finally,a design sketch of constructing the proving ground was given,and a typical test was proposed a set in this scene for the implementation of a virtual test as well as a typical real-time of int...
