Function Based 2 D Flow Animation

This paper summarizes a function-based approach to create 2D flow animations. We use periodic functions to create cyclical animations that represent 2D flow. These periodic functions are constructed with an extremely simple algorithm from a set of oriented lines. The speed and orientation of the flow are described directly by the orientation and the lengths of these oriented lines. The resulting cyclical animations are simply obtained by sampling the constructed periodic functions. Two example applications of 2D flow animations is provided where they are used to improve the visualization of compressor operation.
