As a new and rising technology, virtual reality (VR) has entered to many fields from military affairs. For example, it has entered spaceflight, design, manufactory, information management, trade, entertainment, etc. Many specialists think that VR is a more promising technology in the future. The design of virtual reality system is using advanced hardware technology and software tools to design reasonable architecture and interactive method.In this paper, based on the principle and technique of VR I mainly discussed the construction of Virtual Reality system and VR development software-Vega, specifically studied the design of VR system on the Vega platform. Found on these studies, a model management system is designed.The construction of VR system is complex, involved in many aspects such as computer graphic, object management , interactive equipment disposal, man-machine conversation and artificial intelligence. Vega platform provides advantages for the construction of VR system. In this paper, the technique of Vega windows in MFC-Based applications is studied and implemented, which is prepared for the further more work-more efficient VR system applications.
