摘　　要：在以DIS(分布式交互仿真 )为标准的DVE(分布虚拟环境 )系统构成的大规模虚拟战场环境中 ,视景系统由于其在观察战场、评估作战计划等方面占据了不可替代的重要地位 ,所以在虚拟战场中生成视景的可信性和可靠性日益受到人们的广泛重视。本课题对虚拟战场视景系统的视点变换。As a part of the large scale virtual battlefield environment constructed by DVR (distributed virtual reality) based on DIS (distributed interactive simulation), the image generation system plays an important role in observing battlefield and evaluating the battle scheme. So researchers more and more concern how to construct a highly credible image of virtual battlefield. Extensive studies on some questions relative to image generation system of virtual battlefield have been carried out in this thesis.Firstly, some arithmetics of viewpoint position translation are analyzed in detail, and some merits and defects are compared in different part of virtual environment. Further more, the analysis of the delay in the image generation system of virtual environment is made. And one method of contrail prediction,dead reckoning, is introduced in more detail in the thesis. And then, we applied an image smoothing algorithm to solve the problems brought by DR.
