Lattice-Boltzmann Method (LBM)

A couple of weekends ago I was tinkering with fluid dynamics and implemented a few compute shaders in Unity. Among the ones I implemented, my favorite is the Lattice-Boltzmann Method featured here.

This early implementation allows to draw SDF entities in the simulation space behaving as blockers, inflows or outflows. I intend to expand on the features, but most likely at a slow pace, because this is a no-rush side-project. But I definitely wish to post now and then about my progress.

I also hope to find some spare time soon to write a quick article on how to implement an LBM cellular automata from a light-on-maths perspective.
