Research on Scene Graph of Virtual Maintenance Training System of Missile System

摘要

This article proposes a hierarchically structured scene graph for intuitive and precise solid modeling in virtual reality (VR) environment. Making full of use the advantages of the software of virtual reality and CAD, we present an effective data representation of virtual maintenance training system (VMTS). Final, the system of restriction management is built up and the restriction manage of the virtual environment can be achieved well.
