基于流体模型和GPU加速的火焰实时仿真

针对目前基于物理模型模拟火焰的计算量大、复杂度高,很难进行实时模拟的问题,提出了一种基于流体模型和GPU加速的火焰实时模拟方法,该方法根据火焰的不可压缩、低密度、无粘性等特点,通过流体方程计算火焰的物理属性,并将其求解过程在GPU中并行加速,从而大幅度提高了算法的运算速度,实现了火焰的实时模拟,并取得了较真实的模拟效果。

Real-time Fire Simulation Based on Fluid Model and GPU Accelerated

Due to the problems existing in simulation on physical model of fire,such as heavy calculation,high complexity and difficulty in real-time simulation,a new real-time simulation method was raised based on fluid model and GPU acceleration. This method,based on the physical characteristics of fire,such as incompressibility,low density and inviscid,used the fluid equations to calculate the properties of fire. Then by accelerating this method through GPU,the real-time simulation of fire was realized and a realistic effect was achieved.
