Simulators for dynamic systems are now widely used in various application areas and raise the need for effective and accurate flow visualization techniques. Animation allows us to depict direction, orientation, and velocity of a vector field accurately. We extend a former proposal for a new approach to produce perfectly cyclic and variable-speed animations for 2D steady vector fields [B. Jobard, et al., (1997)] and [C. Chedot, et al., (1998)]. A complete animation of an arbitrary number of frames is encoded in a single image. The animation can be played using the color table animation technique, which is very effective even on low-end workstations. A cyclic set of textures can be produced as well and then encoded in a common animation format or used for texture mapping on 3D objects. As compared to other approaches, the method presented produces smoother animations and is more effective, both in memory requirements to store the animation, and in computation time.
