视景仿真实时显示技术的研究

视景模型实时显示与交互技术是目前分布式视景仿真研究的关键技术。以视景实时显示为目的，探讨了雾化技术、实例化技术、纹理映射技术、纹理裁减、场景模型分块、LOD（level of detail）等技术，重点研究了面向大场景仿真的实时显示问题，通过对各种视景仿真实时显示技术和场景显示调度算法的综合应用，实现了对三维大场景海量数据进行较为流畅的显示，满足了大场景实时显示帧率要求，并具有较好的显示精度和清晰度。

Research on real-time display technology of visual simulation

Real-time display and interactive technology of visual models is the very important technology of visual simulation research recently.Forthe purpose of real-time display of vision,atomization technology,instantiation technology,texture mapping,cliptexture technology,partition of scene models,LOD(level of detail) and so on are discussed,and real-time display of large scale scene is researched emphatically.By using several real-time display technologies of visual simulation and schedule arithmetic of scene display,fluent display of vast data of 3D large scale terrain is implemented,the frame frequency of large scale terrain is achieved and it has very good display precision and definition.
