The Application of LOD in Large-scale Complex Scene Simplification

LI Chang-chun,HE Rong,WANG Bao-shan (School of Surveying and Land Information Engiveering,Henan Polytechnic University,Jiaozuo 454003,China)  
In order to reduce scene complication,improve the speed of loaning in complex scene to meet the demand of real time showing,the method of LOD model simplification was discussed.Based on the LOD classification,different LOD model simplification methods were mainly discussed.Then the paper discussed the basic process and operate method of same-faces simplification with an example.For the sudden interval during models transition,the solve method of smooth amalgamation was discussed,and the vision effect is very good.In the end,how to choose the different LOD was mentioned.For the large scale scene,which has complex geometry structure and depiction,the simplification result is very good.
