In order to have a useful fluid simulator, the fluid has to be in some kind of container or environment, and the fluid needs to interact with this environment. For that purpose, I added support in my little experimental fluid simulator to be able to load an arbitrary polygonal surface and have the individual particles…

About a week ago, I posted a quick video of some early results for a 2D fluid simulation I quickly coded up. Once I got the 2D simulation working the way I wanted, it was only a matter of about a day’s coding to convert the code to simulate 3D fluid dynamics. But one idea…

I’ve been tinkering from time to time with numerical simulations of cloth, fire, clouds, etc. for almost 25 years now. In fact, it was a side project I was doing in college to simulate fire that got me hired as a software developer in the film industry back in the mid 90’s. I haven’t done…
