基于粒子系统理论,提出飞机尾焰建模方法,采用纹理映射技术、多细节层次(levels of detail,LOD)技术对尾焰粒子进行实时渲染,加快了渲染速度,增强了真实感.仿真结果表明,生成的飞机尾焰效果真实,具有良好的实时性,可在普通的PC机上流畅运行,同时给出了雨和雪的特效仿真. Based on the theory of particle system, a modeling method of aircraft tail flame is proposed, which uses texture mapping technology and level of detail (LOD) technology to render the tail flame particles in real time, which accelerates the rendering speed and enhances the realism.The simulation results show , The resulting aircraft tail flame effect is true, with good real-time nature, can run smoothly on an ordinary PC, given the rain and snow effects simulation.
