Fluid Simulation For Computer Graphics: A Tutorial in Grid Based and Particle Based Methods
Colin Braley, Adrian Sandu · 2009
In this paper we present a tutorial on the implementation of both a grid based and a particle based fluid simulator for computer graphics applications. Many research papers on fluid simulation are readily available, but these papers often assume a very sophisticated mathematical background not held by many undergraduates. Furthermore, these papers tend to gloss over the implementation details, which are very important to people trying to implement a working system. Recently, Robert Bridson release the wonderful book, ”Fluid Simulation for Computer Graphics.[Bridson 2009]” We base a large portion of our own grid-based simulator off of this text. However, this text is very dense and theory intensive, and this document serves as easy version for those who want to implement a simulator quickly. Furthermore, Bridson’s text does not cover particle based methods, like SPH, which are quickly becoming commonplace within the graphics community. This work provides an introduction to SPH as well.
