基于弹性算法的矢量场可视化方法的研究

Study of visualization based on flexible algorithm vector fields

分析了二维非稳定场的可视化方法(Unsteady flow Line Integral Convolution,UFLIC),并针对其产生每帧图像费时较多的缺陷,进行了改进。采用弹性算法来控制种子的释放,通过重用、复制相关迹线来减少迹线的积分计算,达到减少生成每帧图像所需的时间的效果。实验证明在生成的图像质量相当的前提下,种子控制算法比UFLIC算法更快。

One weakness of Unsteady flow Line Integral Convolution（UFLIC） was time-consuming to generate frames, the improved method was proposed. The effect that reduced the time of adveet frames was achieved by flexible algorithm and reuse and copy relative pathlines. The resuhs show that our algorithm is fast than UFLIC based on the similar quality of frames.
