摘要
基于粒子系统和空气动力学效应对下雪这一自然现象进行了实时仿真,建立了一个风的模型,把雪的运动看作风的运动和雪的自由落体的综合运动。根据雪粒子的自然属性和飞行模拟实际的视景需求,简化了数学计算,模拟了下雪这一特殊气象。最后对粒子间的碰撞做了简要介绍。
Based on particle system and aerodynamics, real time snow simulation for flight simulator was conducted. A motion model for wind field was built, which represents snow running as a kind of synthetic effect of wind running and snow free falling. Then combining natural snow particle attribution with visual scene demand of flight simulation, the simplification for mathematical calculation and snow motion were made. Finally a brief introduction on collision among the particles and the simulation effect results were given.
