We introduce Hodge-optimized triangulations (HOT), a family of well-shaped primal-dual pairs of complexes designed for fast and accurate computations in computer graphics. Previous work most commonly employs barycentric or circumcentric duals; while barycentric duals guarantee that the dual of each simplex lies within the simplex, circumcentric duals are often preferred due to the induced orthogonality […]

In this article we derive an equation for the velocity of an arbitrary time-evolving implicit surface. Strictly speaking, only the normal component of the velocity is unambiguously defined. This is because an implicit surface does not have a unique parametrization. However, by enforcing a constraint on the evolution of the normal field we obtain a […]

A thesis from 2009 that I missed: Barbara Solenthaler, University of Zurich: Incompressible Fluid Simulation and Advanced Surface Handling with SPH

I was recently asked whether there exists any internet forum dedicated to physics-based animation. The two that came to mind are Gamedev’s Math & Physics forum and Bullet’s physics simulation forums (both linked in the right column of the page), though my impression is that these naturally tend to be focused towards games, and with […]

We present a volumetric iso-geometric finite element analysis based on Catmull-Clark solids. This concept allows one to use the same representation for the modeling, the physical simulation, and the visualization, which optimizes the design process and narrows the gap between CAD and CAE. In our method the boundary of the solid model is a Catmull-Clark […]

By modeling mass transfer phenomena, we simulate solids and liquids dissolving or changing to other substances.We also deal with the very small-scale phenomena that occur when a fluid spreads out at the interface of another fluid. We model the pressure at the interfaces between fluids with Darcy’s Law and represent the viscous fingering phenomenon in […]
