Showcasing the power of the new Safari4 Javascript engine, someone has built a Navier-Stokes equation solver that runs entirely in JavaScript. Simply select the resolution & solver iterations (The default work nicely) then start clicking in the big black box. You can start & stop the simulation, and click the “Toggle drawing mode” to switch between flow glyphs and surface visualizations. The image above was rendered with the simulation on FireFox3.5 beta, running at 5-6fps.
The surface visualizations also allow you to add “density sources” which create some impressive flow visualization effects. Is this the future of simulation/visualization on the web? I doubt it, but it’s pretty kewl either way.
