Intelligent Vehicle Systems 3d Simulation Of The System Platform Architecture

A virtual reality system describing the method of storages and calculations for the plane model and the curving model has been designed, which not only rectifies the distortion of model and the abnormity of texture mapping, but also presents a storage pattern of the complex 3d model on Internet with less data streams.The file containing information of the scene is defined as the interface between the modeling application and rendering application. The interface gives two types of saving template, providing a discriminating standard for the rendering of plane models and NURBS models that coexist in the rendering application. To avoid pipeline leaving unused in the course of NURBS models' pretreatment, multithreading application is created for rendering. In order to simulate ray trace reflection effect, the mirror reflection and curving reflection have been distinguished, giving an predigest method simulating approximate the ray trace effect by use of mirror geometry and the middle curving surface texture mapping. Based on the realization of the 3D simulation, the artificial intelligence also has been applied in the virtual reality scene.Some problems of VR graphics technique occurring in the practice have been resolved via the research of the thesis. It provides the reference and expands the thinking for more advanced and extensive researches.
