摘要
虚拟场景往往存在精度不高和运行效率低的问题,本文引入细节层次技术(Level of Detail,LOD),给出了网格简化的方法和误差评价指标,在此基础上建立虚拟场景的模型,并以某一区域的建筑物作为研究对象,验证模型的可行性。
Aiming at the problem that the visualization accuracy is low and the efficiency is low in the virtual scene,this paper uses the Level of Detail(LOD),gives the model simplification method and the error evaluation index.On this basis,the model of the virtual scene is established The feasibility of the model is verified by the building of a certain area.
