Abstract:


In this work we present an approximation of surface tension intended to create more visually plausible results of a large-scale fluid simulation for Computer Graphics applications. We modify the computation of the Navier-Stokes equations to work with an alternative version of the velocity field that includes our additional logic. We describe how to compute this additional information and how to store it. This leads to more realistic results of the simulation with only a minimum increase in computation time. After presenting some background information, we show the details of how our algorithm accomplishes its goal and then we present some results and the corresponding analysis.
