摘　　要：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。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 discussedl 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 interaction.
