基于Vega Prime的视景仿真技术研究与应用

文章针对Vega Prime视景仿真技术相对于Vega的改进之处，设计了基于Vega Prime的视景仿真框架，重点研究了四个方面内容：运动模型和仿真对象的特点及两者之间的驱动关系、坐标系统和不同坐标系之间的转换机制、碰撞检测器的原理和碰撞检测的方法、用于模拟环境效果的”天历表模型”和模拟特殊效果的粒子系统等等。论文解决了基于Vega Prime的视景仿真技术涉及的诸多关键技术，为Vega Prime在实践中的有效应用打下良好基础。最后，论文还分析了基于Vega Prime的场景漫游过程，并把文章研究的相关理论应用到实践。

Research and Application of Scene Simulation Technique Based on Vega Prime

This paper designed scene simulation framework based on Vega Prime,and mainly researched four parts: characteristic and drive relation of movement model and simulation object;reference frame and coordinate conversion of different reference frame;the principium of collision detection and the method of collision detection;"ephemeris model "for simulating circumstance effect and particle model for simulating special effect.This paper solved many problems of scene simulation based on Vega Prime,which created preferable foundation for the application of Vega Prime in practice.In the end,this paper also analyzed the process of scene cruise on Vega prime,and applied the theory of this paper to practice.
