Wow, the demo in the YouTube video looks impressive. I would like to understand the technique they propose and what's unique in their thinking. Can someone with expertise on this topic explain the abstract in layman's terms?<p>Abstract: We propose a novel surface-only technique for simulating incompressible, inviscid and uniform-density liquids with surface tension in three dimensions. The liquid surface is captured by a triangle mesh on which a Lagrangian velocity field is stored. Because advection of the velocity field may violate the incompressibility condition, we devise an orthogonal projection technique to remove the divergence while requiring the evaluation of only two boundary integrals. The forces of surface tension, gravity, and solid contact are all treated by a boundary element solve, allowing us to perform detailed simulations of a wide range of liquid phenomena, including waterbells, droplet and jet collisions, fluid chains, and crown splashes.
That looks pretty @%(*ing compelling. Does anyone know how novel this is, and whether it would be computationally feasible to implement in real time (e.g. video games?)<p>I could already see it being very useful in for offline 3D animation, such as animated movies.
Wow. Some years ago, I spent significant time on simulating 2d fluid for games. Here is one version of it: <a href="http://jsexperiments.herokuapp.com/sph/" rel="nofollow">http://jsexperiments.herokuapp.com/sph/</a><p>Ofcourse, this is completely different beast.
