A Multiscale Approach to Mesh-based Surface Tension Flows

SIGGRAPH 2010 paper: A Multiscale Approach to Mesh-based Surface Tension Flows
Nils Thürey, Chris Wojtan, Markus Gross, and Greg Turk

Abstract: We present an approach to simulate flows driven by surface tension based on triangle meshes. Our method consists of two simulation layers: the first layer is an Eulerian method for simulating surface tension forces that is free from typical strict time step constraints. The second simulation layer is a Lagrangian finite element method that simulates sub-grid scale wave details on the fluid surface. The surface wave simulation employs an unconditionally stable, symplectic time integration method that allows for a high propagation speed due to strong surface tension. Our approach can naturally separate the grid- and sub-grid scales based on a volume-preserving mean curvature flow. As our model for the sub-grid dynamics enforces a local conservation of mass, it leads to realistic pinch off and merging effects. In addition to this method for simulating dynamic surface tension effects, we also present an efficient non-oscillatory approximation for capturing damped surface tension behavior. These approaches allow us to efficiently simulate complex phenomena associated with strong surface tension, such as Rayleigh-Plateau instabilities and crown splashes, in a short amount of time.

Very cool Simulation!

What program did you use to render the algorithm? Blender?

[nthuerey]

@Cryto Thanks, we used Maya & MentalRay to render this, but Blender & Yafray would probably also give cool results...

@Rottensteam because it takes half an hour per frame

[Rottensteam]

Why dont we see this in games?

[kirkeric]

Damn that is good.

[MrRocodromo]

Awesome

[bigquix]

great! I love it!

[CoreVfx]

Amazing, really cool!!

Is this a plug-in, and if it is where do you get it?

Also can u use 3ds max instead of maya to preform this simulation?

[LiquidxEviL]

JIZZ!!!

The most realistic water simulation algorithms to date, well done guys.
