基于布料模型的可交互火焰模拟

火焰等不规则物体在空间和时间上的多变性,使得该类物体的模拟问题一直是图形学的难点。针对传统的模拟方法耗时且真实性不理想,提出了基于布料模型的火焰模拟方法。首先分析了利用simplex噪声来模拟火焰的方法原理,在此基础上,结合布料模型方法进行火焰低频信息绘制,通过基于GPU的快速方法提升模拟效率。实验证明,该方法模拟火焰的真实性与实时性较传统方法有很大提高,同时还可以和不同风速场交互。

Interactive Fire Simulation Based On Fabric model

Fire and other irregular objects is variability in space and time, this make the simulation of such objects become a difficulty problem of graphics. The traditional method of efficiency and authenticity is not satisfactory,this paper propose an interactive fire simunlation based on fabric model.First analyzed the principle which used the simplex noise to simulate,then used fabric model to drew low-frequency information of fire,through a GPU-based fast methods improve efficiency. Experiments show that, all these measures contribute to reach a desirable realtime simulation speed and acquire an improvement of performance,also can interact with different wind field.
