Abstract:

This paper is based on the study of the roaming system about the campus.Though three-dimensional modeling and texture mapping,using the technology of 3D virtual reality,the on-line tour of main viewpoints for 3D virtual reality scenes of the campus is achieved.Using different methods to construct sky modeling,building modeling and tree modeling separately,the virtual campus is really rebuilt.Then,some methods for optimization are adopted in order to reduce the data of the model file and accelerate the speed of the load scenario successfully.

Key words: virtual reality;construction modeling;optimization modeling;VRML
