| 摘 要： | 非稳定矢量场可视化是科学计算可视化中最具挑战性的课题之一。分析了二维非稳定场的可视化方法UFLIC,并针对其产生每帧图象费时较多的缺陷,进行了改进。采用种子控制算法来控制种子的释放,通过重用已保存的相关迹线来减少迹线的积分计算,达到减少生成每帧图象所需的时间的效果。实验证明在生成的图象质量相当的前提下,种子控制算法比UFLIC算法更快。

| Abstract: | Unsteady vector fields visualization is one of the most challenge research tasks of visualization in scientific computing.This paper analyses UFLIC.One weakness of UFLIC is time-consuming to generate frames,the improved method is proposed.The effect that reduces the time of advect frames is achieved by control released seeds and reuse pathlines which have been saved.The results show that our algorithm is fast than UFLIC based on the similar quality of frames. |
