Virtual Reality Technology - By Multigen Vega Applied Research

Virtual Reality (VR) which is a new and rising computer crossing application technology has vast application prospects.lt can be used in very wide fields.the design of virtual reality system is using advanced hardware technology and software tools to design reasonable architecture and interactive method.In this paper,we mainly discussed the construction of Virtual Reality systemand VR development software------MultiGen Creator and vega. This paperincludes six parts.In the first part,a brief introduction to the characteristics ^ system construction and critical technology,together,the research and development of Distributed Virtual Reality is presented.In the second part,mainly introduce the establishment of Virtual Environment, the principle of stereo vision and Input/Output device,computer and the software environment of Virtual Reality ,then we can put up a platform of VR system.In the third part ,the MultiGen modeling technology is discussed,we discuss the system construction of MultiGen ,the structure of Open Flight format and the key technology of MultiGen.In fourth part,the construction of vega is introduced.firstly we discuss IRIS Performer which is the base of vega,then the theory of 3D graphics draw,we put emphasis on hierarchical structure of vega class and the basic class of vega, Also ,the Distributed vega is disccused. At last we discuss vega special effect model.In fifth part we use MultiGen and vega implement a system which is a virtual areola we can walk through ,the modeling of the system and the motion model is mainly discussed.The last part mainly discuss the application and the future of VR technology.
