Virtual Reality Internet Application--Study And Development On The E-Commerce System Of Real Estate

Based on the basic theories of Computer Graphics,Virtual Reality,Network Technology and the detailed Feasibility & Requirement Analysis of the Real Estate Applications,using Object-oriented Software Engineering Methods,applying VRML&JAVA,this article expatiates on the implement of system framework and database designs,code development and testing,finally publishes a practicable multi-function Real Estate E-Commerce Software System focuses on the Real Estate virtual 3D scenes touring.In order to solve the issues of multiple graphics interface,Real-time display and realism immersion in the Virtual Reality System,this article especially studies on the various Real-time algorithms in the geometric,physical and behavior modeling processes of the Real Estate scenes. Taking the related researches as basis,this article puts forward an improved anti-aliasing fast algorithm,which greatly enhances the texture mapping speed and quality. Furthermore,this article firstly presents the synchronized playing technique of 3D scene,2D scene and scene explanation,which enlightens an entire new area in the native Real Estate Virtual Reality Applications.
