摘要
空间环境可视化仿真体系对于管理、分析、展现空间物体工作方式至关重要。结合计算机图形学,天文学,数学,运动学等知识,建立了一个以地球为中心的空间环境仿真平台,在此基础上开发出卫星在轨运行实时仿真系统。对仿真系统的设计及实现进行了详细地描述,并论述了系统的主要功能和框架、场景的几何建模和动态建模、卫星覆盖范围建模、通讯特殊效果实现、分布式显示等关键技术。实践结果表明,仿真及显示效果形象逼真,并满足实时性要求。
The visual simulation architecture of space scene is very important in managing,analyzing and displaying the space objects.With the knowledge of computer graphics,astronomy,mathematics,and kinematics etc.A platform of space scene,which mainly focuses the earth,is developed.In addition,a visual simulation system of satellite motion in orbit based on the platform is also developed.This paper describes the design and the implementation of the platform and the visual simulation system.Some key technologies are involved,such as overlay area modeling,geometry modeling and kinematics modeling,communication special effect modeling and distributed displaying.The simulation results show that the visual effect is vivid and realistic,and can meet the requirement of real time visual system.
