Title:  Flow Tiles
		
Abstract:

Velocity fields are an integral part of many computer graphics
applications, such as fluid animations, wind fields, and as guides
for animated characters. In practice, the use of velocity fields in
interactive environments is limited by the expense of storage and
the difficulty of designing fields to satisfy boundary conditions
and other properties. In this talk I describe flow tiles, a novel
approach to designing and evaluating velocity fields. A flow tile
is a small region of flow. Large fields can be created by tiling
a set of prototypical flow tiles, much as computer games create
terrain by combining terrain tiles. The advantages to tiling include
efficient computation and memory usage, interactive design of large
fields, and easy embedding into virtual environments. Three
applications are presented: a river flow, characters guided through
city streets, and swirling fog.
