Yes, we can since a long time. They were already a thing 14 years ago on the PS3 in the game "Pixeljunk shooter" [0].
But real time simulations often use massive simplifications. They aim to look real, not to match exact solutions of the Navier-Stokes equations.

- mcphage 3y agoHeck, the Wii had Fluidity around the same time period (2010), and that's a lot weaker than the PS3. Fluidity was pretty neat—you played as a volume of water, changing states as you moved through a level that looked like a classic science textbook:https://youtu.be/j7IooyXp3Pc?si=E79rCrq2mdyZSKoF&t=120 https://youtu.be/j7IooyXp3Pc?si=E79rCrq2mdyZSKoF&t=120
- s-macke 3y agoWell, technically yes. Both use the same technique: Smoothed Particle Hydrodynamics. But the PS3 was able to fill the whole screen with these particles. Hundreds of them. The game Fluidity seems to have approx. 20.

- kragen 3y agothanks, i had no idea about pixeljunk shooter! it looks like those fluids are 2-d tho. otoh it's apparently performing a multiphysics simulation including thermodynamics btw, almost unrelatedly, you have no idea how much i appreciate your exegesis of the voxelspace algorithm
