A Stream Function Solver for Liquid Simulations

Ryoichi Ando, Nils Thuerey, Chris Wojtan This paper presents a liquid simulation technique that enforces the incompressibility condition using a stream function solve instead of a pressure projection. Previous methods have used stream function techniques for the simulation of detailed … Continue reading

Double Bubbles Sans Toil and Trouble: Discrete Circulation-Preserving Vortex Sheets for Soap Films and Foams

Fang Da, Christopher Batty, Chris Wojtan, Eitan Grinspun Simulating the delightful dynamics of soap films, bubbles, and foams has traditionally required the use of a fully three-dimensional many-phase Navier-Stokes solver, even though their visual appearance is completely dominated by the … Continue reading

Subspace Condensation: Full Space Adaptivity for Subspace Deformations

Yun Teng, Mark Meyer, Tony DeRose, Theodore Kim Subspace deformable body simulations can be very fast, but can behave unrealistically when behaviors outside the prescribed subspace, such as novel external collisions, are encountered. We address this limitation by presenting a … Continue reading

Restoring the Missing Vortices in Advection-Projection Fluid Solvers

Xinxin Zhang, Robert Bridson, Chen Greif Most visual effects fluid solvers use a time-splitting approach where velocity is first advected in the flow, then projected to be incompressible with pressure. Even if a highly accurate advection scheme is used, the … Continue reading

Power particles: An incompressible fluid solver based on power diagrams

Fernando de Goes, Corentin Wallez, Jin Huang, Dmitry Pavlov, Mathieu Desbrun This paper introduces a new particle-based approach to incompressible fluid simulation. We depart from previous Lagrangian methods by considering fluid particles no longer purely as material points, but also … Continue reading
