A research on 3D visualization of real estate surveying information in Web environment

CHENG Liang,ZHANG You-jing②,GONG Jian-ya,SONG Xiao-gang③(State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing, Wuhan University, Wuhan 430079;②State Key Laboratory of Hydrology-Water Resources and Hydraulic Engineering, Hohai University, Nanjing 210098;③Remote Sensing and Information Engineering School, Wuhan University, Wuhan 430079)  
There are still some difficult problems on realization of 3D visualization on web.Compare with single computer and LAN environment, network response time will largely influence the results of 3D visualization in Web environment.According to this problem, this paper focuses on 3D modeling' efficiency and 3D Scene data amount, analysis the shortages of existing methods, puts forward an effective solution to shorten network response time, in order to realize 3D visualization of Real Estate Surveying on web.This paper introduces the key technologies and methods, such as the method on real-time 3D scene’ construction of Real Estate Surveying information on web based on model library, and the method on 3D modeling based on module and reference.The test system proved that the solution is useful and effective.
