GPUs are making this the era of high powered desktop computing and to prove the point what about a nice example of fluid simulation - video and code included.
The idea is to get close to the physics by solving the Navier-Stokes equation so the smoke you see swirling around the cylinder isn't just a special effect but a simulation of the fluid flow. Watch the video to see how it performs. It is worth mentioning that the video is a representation of the simulation in realtime - that is it is what you see when you run the program.
Sometimes you see a video and really can't make up your mind if this is good, bad or just silly. In this case we have quadruped robots masquerading as garden lanterns in a traditional Japanese style. [ ... ]
