Virtual reality technology is the 20th century before the rise of a comprehensive high-tech information technology . It combines digital image processing, computer graphics , artificial intelligence , multimedia technology , sensors, networks and parallel processing technology and many other information technology, three-dimensional space constituted by a computer to produce an artificial virtual environment , enabling people in a variety of senses to produce a sense of immersion in the virtual environment . Virtual reality technology developed in our country has also taken off and has made important progress. China has in the construction industry , medicine, the military , education and training, business and other fields made ??a good start, but it reached the level of practical application is not very high . This review focuses on virtual reality technology in house planning and design of the application of the research, the main research work and results are as follows : at this stage, based on the traditional graphical modeling , using the back-face culling , blanking , brightness calculation , texture mapping method the realization of three-dimensional graphics modeling stage algorithm analysis , while ensuring at the same time greatly improved graphics photorealistic real-time rendering efficiency. EON Reality software enables the use of three-dimensional image generation and processing, observation and operation control , analytical applications . Try a company has been in office , and achieved good results.
