摘　　要：为解决大地景仿真时显示逼真度与画面流畅度相互制约的问题,对基于地形生成系统(creator terrain system,CTS)的大地景仿真进行参数优化设计。结合某型飞机飞行仿真系统研制实例,分析地形纹理和地形模型的生成原理,给出其参数设置,重点研究重要参数对纹理和地形生成的影响。仿真结果表明,该设计能有效解决地景逼真度与流畅度互相制约的难点。To solve the problem of mutual restraint between display fidelity and display fluency on large-area landscape simulation, the large-area landscape simulation parameters were optimized design based on CTS. Combined with an example of certain type aircraft flight simulation system, analyzed the generation principle of terrain texture and terrain model, giving its parameter settings, focused on the influence of important parameters for texture and terrain generation. The simulation results show that the design can effectively solve the mutual restrain between fidelity and fluency.
