摘要：
For now, the research and implementation of dynamic terrain are all based on OpenGL. In order to realize virtual field experiments of agro-machinery in the Vega Prime virtual reality platform, a real-time visualization method of wheel ruts based on class vrGeometry in Vega Prime was proposed. Firstly, the small three-dimensional terrain is established in Multigen Creator, the 3d terrain models of variable points are redrawn and generated and the terrain models are generated and loaded quickly by using multithreading technology. Then the collision points between wheels and the ground are obtained by collision detection, and Multi-Thread technology is used to search the vertices on the terrain near collision points synchronously and quickly, then the real-time dynamic wheel ruts are produced by modifying coordinates of the vertices and updating the terrain data real-time.
