We want games to be fun and look pretty and plausible.
Fluid simulation can augment game mechanics and enhance the aesthetics and realism of video games. Video games demand high performance on a low budget but not great accuracy. By low budget, I mean both computational and human resources: the game has to run fast, and it can’t take a lot of developer or artist time. There are many ways to simulate fluids. In this series, I explain methods well suited to video games: cheap, pretty, and easily written.
