Using virtual reality technology for environmental design,
and integrated real-time three-dimensional simulation graphics
and information, which is a new attempt. At present, many
research institutions, colleges and universities have been
carrying out the use of this technology in architectural design,
urban planning research. One of its main purposes is create a
virtual 3D environment in the planning, design stage. So that
people can immersive, all-round look at the future of the
building or city with a dynamic interaction. And people can
know the geographic information in this virtual 3D
environment [4]. The traditional architectural rendering and
playback of 3D animation can not achieve this effect.
