在驾驶训练虚拟场景建模中的网格模型简化

Mesh Model Simplification on Virtual Scene Modeling of Driving Training

随着对虚拟场景真实性要求不断提高,制作的场景越来越精细、复杂,所占用的存储空间和计算数据量增大,导致运算处理速度降低,影响实时性。建立真实且数据量小的虚拟场景模型成为研究热点。通过顶点聚类算法进行网格模型简化,生成多种细节层次的模型应用到场景中,在保证真实性的前提下,满足实时性要求,取得良好的效果。

With the increasing demands on the realness of virtual scene, scenes are made more and more fine and complex, and storage space and data increase, so that the processing speed reduces and timeliness is influenced. The establishment of virtual scene models both real and with small amount of data becomes a hot topic. In this paper, the vertex clustering al- gorithm is used to simplify the mesh model, a variety of LOD models are generated and applied to the scene, which ensures realness and timeliness and achieves good effect.
