基于粒子系统的流场实时模拟

Real-time simulation of flow field based on particle system

数学模型计算结果的显示大多以后处理的形式出现,存在显示时间滞后、存储数据量大、无交互性等方面的不足.应用计算机图形学中的粒子系统来模拟流场,通过分析粒子的存储结构和出生、发展、消亡的生命历程对流场模拟的实时性和模拟效果的影响,从显示方面提高了系统运行的实时性与真实性;采用调整显示时间的方式实现计算和显示时间同步及数据的实时传输,开发了集实时计算和显示于一体的流场模拟系统.

In scientific visualization, most results could not be displayed until the calculation of numerical simulation was completed. Therefore, some shortcomings were showed such as the display was hysteretic, the storage for result data was huge, and there was no alternation in simulation system. In this paper, the particle system was used to simulate flow field. By analyzing the storage structure of particle and the course of particle life, the quality of real-time display and reality were apparently improved. Moreover, the real-time data transport and in-phase for display and calculation were achieved by adjusting the time interval of display and data interposition. Based on the above methods, a real-time flow filed simulation system was realized.
