The Design And Realization Of 3D Animation Technology In Real Estate Information System

Faced with increasing competitive pressure and the diverse needs of the market, a growing number of real estate companies began to be applied to the visual image of virtual reality technology in real estate sales presentations to promote the growth of sales. In the virtual reality technology, VRML and X3 D are very important methodological standards. VRML(Virtual Reality Medaling Language, Virtual Reality Modeling Language) defines the language used to create a three-dimensional scene fictional model. The X3D(extended three-dimensional) define multimedia integration of international standards for the dissemination of web-based interactive three-dimensional graphics. Based VRML/X3 D virtual reality technologies has been widely used in the medical, entertainment, military, manufacturing, real estate and other fields.This thesis topic based on VRML/X3 D technology, design and implementation of a system of virtual real estate show. VRML language modeling and visualization software the auxiliary model design, using the LOD algorithm optimization virtual show the interactive features of the system, application JavaScript language extensions demo system. System graphical interface for traditional real estate show a single, graphical real-time interactive real sense of immersion and poor, and focus on the real estate the three-dimensional scene realistic modeling techniques and interactive functions, and system implementation process in a variety of real-time processing technology and strategy application Trying to improve the image quality of texture mapping, and improve the image texture mapping speed.This thesis describes the design and implementation of the system of virtual real estate show, elaborated on the issues involved in software development technology, delved into the virtual reality modeling techniques and optimization methods in modeling programs. Finally, the thesis to achieve the results display system based the VRML/X3 D simulated real estate and the topic next step planning.
