基于OGRE的三维红外云仿真

根据实际需要简化了云的辐射模型,利用Modtran软件对整个场景的大气进行计算,得到大气路径辐射和透过率。再通过GPU的并行处理对整个数据进行采样,模拟出大气辐射传输效应。最后通过OGRE的粒子系统模拟出三维云体,结合云的自身辐射特性和大气效应模拟出三维红外云场景。仿真结果表明,生成的三维红外云场景有较好的真实感和实用性,为后续其它研究提供基本数据。

Simulation of Infrared 3D Cloud Based on OGRE

The cloud radiation model is simplified according to the actual demand,and atmospheric transmittance and atmospheric radiation of the whole scene are calculated using Modtran.The data is sampled using the computer parallel processing technology of GPU,and the effect of atmospheric radiation transfer is simulated.Finally the simulation of three-dimensional cloud is achieved using the particle system based on OGRE and the simulation of the three-dimensional infrared cloud scene is achieved based on the characteristics of cloud radiation and the atmospheric effect.The results show that the simulation of the three-dimensional infrared cloud scene is realistic and practical and can be used as basic data for later research.
