Also known as virtual reality or virtual reality environments virtual environment, is rapidly developing a comprehensive computer and interactive graphics technology, which integrates computer graphics, multimedia, artificial intelligence, multi-sensor, network parallel processing, the use of computer-generated three-dimensional space image synthesis technology to achieve the goal, through visual, hearing, touch, in order to render the graphics and animation, the viewer, "seeing is bright." Virtual reality technology is an integrated building design approach, designed to reduce labor intensity, shorten the design cycle, improve design quality, saving investment. Designers to design the building and engineering units can communicate with each other on the World Wide Web.
