Research And Application Based On Virtual Reality Platform Multigen Vega

This paper discusses the corresponding technologies related to Virtual Reality(VR) Simulation programming during the research, and represents the whole developing process of'Virtual Sailing Yacht Exhibition'project based on Vega technology.First, this paper discusses the modeling technology of VR, makes comparison among several popular 3D design softwares. The paper introduces the Modeling technology based on Multigen Creator software as well as the popular OpenFlight model format. It also proposes the optimization technology of the models created for simulation.Second, the paper discusses the developing method for VR simulation based on Multigen Vega, introduces the structure of Vega software, analyses the developing steps, proposes a method for developing Windows style simulation programs combing Microsoft Foundation Class with Vega, and gives the collision detection principle of Vega.Third, the paper discusses the Character Simulation technology, proposes a rapid character modeling way by using multiple modeling softwares, realized the Character Simulation in Vega by utilizing professional Character Simulation software DI-Guy. Forth, the paper discusses the Fluid Simulation theory as well as marine simulation technology. Grid method is adopted for solving 2D wave equation. It also gives a detail description of Vega Marine module, and the marine simulation method based on Vega is proposed as well.Finally, the paper shows the developing process of'Virtual Sailing Yacht Exhibition'project, discusses the coupling mechanism between wind and sail, realized the simulation of wind field, adopts 2 DOF motion platform for synchronizing the postures of virtual sailing yacht model in Vega and the Motion platform. Part of the Source Code for simulation is also given.
