Fire simulation sandbox, more realistic and accurate. You can create fire,
draw wooden or stone walls, burn them up, create particles, air emitters
and burn it all with a fireball.
Enjoy!
This is the latest version, rewritten to javascript.
You can try also Water Simulation or Flame Painter procedural brushes or a new Rebelle real-media paint program.
Here you can find more experiments.
The fluid simulation is based on Jos Stam fabulous paper Real-Time Fluid Dynamics for Games, you can find more of his projects here.
