摘要
建立了日、月、地球以及各类航天器的三维实体模型,利用视景仿真软件Vega实现了实体模型的驱动与场景特效的渲染,并利用Vega的回调机制绘制出星空背景,初步构建了一个虚拟的空间场景。系统引入图形集群,利用其强大的分布式计算与图形渲染能力,结合分布式Vega良好的帧同步特性,建立了双通道、八节点的被动立体投影环境,大大增强了系统的实时性与沉浸感,取得了良好的仿真效果。
Three-dimensional （3D） models like sun, moon, earth and all sorts of spacecrafts were produced. The simulation of 3D models and special effects in scene was performed within the Vega development environment, and the celestial background was drawn by the callback function of Vega. Generally, the virtual space scene was constructed by now. Combining graphics cluster which had powerful parallel computing and graphics rendering capabilities with distributed Vega, the system built a two channel, eight nodes passive stereo projection environment. The system＇s real-time performance and immersion were greatly improved. The test result is good.
