Multigen Creator / Vega-based Virtual Campus Study

With the concept of digital globe, digital city's statement, with the rapid development of computer technology, the three-dimensional modelling tool's optimization, the virtual reality technology as one of digital globe's key technologies, its application is getting more and more widespread. At present, virtual reality technologies has obtained the widespread application on entertainment, medical service, project and building, education and training, science and financial visualization.The virtual campus is the digital campus in the scope and function extending, this paper has realized the virtual campus three-dimensional simulation and real-time roaming with the MultiGen Creator/Vega software in Kunming University of Science and Technology XinYing campus.This paper mainly introduce three dimensional modelling method of different entity in virtual campus scene,such as data collection and pretreat, the three-dimensional modelling, the texture pasted the Figure.These methods mainly included the terrain modelling, the terrain feature modelling, the natural environment modelling. Especially introduce how to process DEM from character information in the terrain data pretreat;In the texture data's pretreatment, introduced the ordinary texture, the transparent texture manufacture process. And has analyzed the key techniques in the three-dimensional modelling.At last, the paper carried out the range of virtual campus using the view engine tool Vega, it has established the different roaming way, established the corresponding collision to examine the mechanism.
