Animated velocity fields is an important tool in understanding such complex phenomena. This paper looks at a number of techniques that ani-mate velocity fields and propose two new ahematives. These are texture adven-tion and streamline cycling. The common theme among these techniques is the use of advection on some texture to generate a realistic animation of the velocity field. Texture synthesis and selection for these methods are presented. Strengths and weaknesses of the techniques are also discussed in conjunctions with several examples. Key Words and Phrases: texture advection, streamlines, droplets, color table ani-mation, LIC, texture mapping, flow field.
