Animation of Soap Bubble Dynamics, Cluster Formation and Collision

Abstract

What is happening when a soap bubble floats on the air? How do bubbles coalesce to form beautiful three-dimensional clusters? The physical-based model and animation described herein provide the answers. This paper deals with a complete computer simulation of soap bubbles from a dynamic perspective, which should prove to be of great interest to physicists and mathematicians. We discuss the dynamic formation of irregular bubble clusters and how to animate bubbles. The resulting model takes into account surface tension, film elasticity, and shape variations due to gravity and external wind forces.
