Developer Unbounds Million-Particle Fluid Simulation in VRChat via Hash Grid

Developer Michael Moroz built a hash-grid-based real-time fluid simulation in VRChat supporting up to one million unbounded particles, plus manipulators like attractors and gravity reversal. The author also explained why hash grids outperform sparse tree grids for neighbor lookups.
