行星际飞行仿真视点运动控制算法设计

Algorithm Design for Viewpoint Movement Control of Interplanetary Flight Simulation

地球外层空间环境的特殊性阻碍了人类认知空间环境变化规律,针对行星际飞行仿真距离尺度大、对象关系复杂、感知能力差等特征,建立了以日心黄道坐标系为基准的太阳系空间坐标体系,设计了视点运动控制机制,提出了一种行星际飞行仿真视点运动控制算法。算法基于最小和最大视距动态调整各仿真对象缩放比例,实现了各类仿真对象在大尺度空间距离快速切换条件下的精确运动定位。经仿真验证,上述视点运动控制算法能够较好的适用于行星际飞行仿真。

The particular environment of the space blocks people to research it.For the visual simulation of space features such as enormous distance,poor perception ability and complex relation description among visual objects,this paper built a solar coordinate system based on J2000 heliocentric ecliptic coordinate system and designs the control mechanism.The author presented a viewpoint movement algorithm for the interplanetary flight simulation,which allows the dynamic adjustment of the scale of the visual objects based on the minimum and maximum sight range,and the exact motion location of visual objects under conditions of fast handover in the enormous distance.Simulation results prove that the algorithm is well suited for the interplanetary flight simulation.
