Simulating Air Bubbles for Computer Generated fluids

Most of the available literature on fluid simulations has not included air bubbles. This paper presents a technique to add air bubbles to a pre-computed or dynamically calculated fluid simulation. Bubbles form naturally in splashing water so the omission of bubbles detracts from the believability and visual realism of a fluid simulation. In this paper I propose a particle-based system that can be implemented with any particlebased simulation of a fluid. The bubble particles are only created where needed and their movement is then dynamically simulated according to the flow of the fluid into which they are introduced.

Representing Breaking Waves in Computer Graphics

The animation and control over fluid simulation is an intricate and testing application of computer graphics. In this report we study the propagation and dynamics of water waves, and look at examples of how waves have been represented in computer graphics in the past. We take ideas outlined in recent papers and develop a tool of our own that generates a representation of a breaking wave surface in Maya.
