空海一体虚拟战场环境构建技术OACSTPCD
Building Technology on Virtual Synthetic Air-sea Battlefield Environment
针对海军空海一体虚拟战场环境仿真平台演练需求,构建了 3 种仿真计算模型,即天空场景仿真模型、海浪场景仿真模型和海面光照模型.利用通用天空标准亮度分布模型,进行亮度计算、颜色空间转换、颜色校正和顶点颜色映射,实现不同经纬度地域、不同时间、不同天气状况下天空动态场景的实时仿真;通过对方向谱进行离散采样,提取单元波振幅、频率、传播方向等参数,构造FFT计算模式快速合成大量单元波实时生成海浪;建立海面光照模型,应用GPU着色技术,将动态天空的变化在海浪…查看全部>>
According to counter simulation exercise requirements for naval multiple weapon platforms, sky scene simulation model, ocean wave simulation model and ocean surface optical model were built. First, a method for simulating dynamic real-time sky background image varied with different region, different time and different weather conditions was discussed. After sphere sky geometry model was built, any arbitrary sky element luminance could be computed based on CI…查看全部>>
