Sebastian Lague builds a particle-based fluid simulation from scratch in C# and HLSL for Unity, one of his Coding Adventure videos. The accompanying GitHub repository links to the research papers behind the method.

HN people recommend it as a practical, from-scratch intro to fluid simulation that is fast enough for real-time use.

If all you want is 2D fluid flow with points, than Sebastian Lague's talk is very practical for the frame-rates he hits: ▶ this video It should port over if you are not hitting super fine granularity, and the collision model for the sprites is simplified. Some of the Babylon.js fluid examples still need a bug report: link Have a wonderful day =)

I recently watched this video about implementing a simple fluid simulation and found it quite interesting: ▶ this video

Sebastian Lague recently did a video on simulating fluids, which may be interesting. As always, he takes a "from scratch" approach to it. ▶ this video The GitHub repository also contains links to some of the research papers used to implement the simulation. link
