Research Of Visual Reality 3D Modeling Technology

In recent years, Virtual Reality (VR) technology has been paid extensive attention in computer field. Virtual reality technology is designing a lifelike virtual environment based on the computer technology, which can access interaction between the user and the environment by use of the essential device.This paper is supported by the national 863 Plan granted Project, the 3D Scene Simulation System of the Satellite Launch Site and Rocket Launching. Satellite Launch Site is the object of the system, which aims to build a general 3D scene simulation platform for satellite launch sites and satellite launching, and accordingly assists satellite launching tasks such as monitoring and safety guardance.The author developed the virtual reality system of the digital launch site in MultiGen Creator and Vega environment, which realized the digitalization of launch site, real-time simulation of Satellite Launch and assistant of Satellite launch mission.The specialization of the digital space launch site and visual flight simulation system makes the thesis possess the representativeness of Virtual Reality modeling. For solving the contradiction between real-time and reality, the paper researched the key modeling technology,and then the paper proposed the effective approaches for real-time improvement based on MultiGen from the aspect of structure optimizing and modeling optimizing. Just so the proposed theory and methods in the paper has a certain extent reference worth for 3D modeling technology, real-time visual scene simulation and virtual reality system.
