Abstract: Vector fields visualization is one of the most challenge researches of visualization in scientific computing. A new method about create, protract and display streamlines step by step based on time delay is presented. It can accurately depict topology, direction and velocity at any points of 2D steady vector fields as a form of animation. It can be proved that the method presented in this paper is simple, visual and imaginable.

Key words: Vector fields visualization, Animation, Streamline, Time delay

摘要： 矢量场可视化是科学计算可视化中最具有挑战性的研究课题之一。该文提出了一种基于时间延迟逐步生成、绘制和显示流线的方法，从而把稳定的二维矢量场的拓扑结构、方向、速度等特征以动画的形式显示出来。实验证明此方法简单、直观、形象。
