摘要
本文针对目前Vega环境中观察者视点定位方法进行了分析,对当前国内外有关Vega环境中自定义视点问题进行了总结。在分析Vega中观察者观察场景原理的基础上,提出了一种全角度视点模型,并对该模型算法进行了系统研究。最后,通过仿真实验,总结了该算法的优势所在。
Aiming at the limitation of the eye point position fixing method in the Vega environment,the observer scene principle of Vega is analysied,and the custom view problems of domestic and foreign relevant Vega environment are summed up.On the foundation,a eye point model about all orientation is carried out,and the arithmetic of model is detaily assayed.Lastly,the vantage of arithmetic is summarized by a simulation experiment.
