Differentiable simulation of soft bodies is a foundation for system identification, trajectory optimization, and Real2Sim transfer. Yet, existing methods such as the differentiable Projective Dynamics (Diff...

Simulating large-scale free-surface water by coupling a localized 3D fluid solver to a cheaper 2D surface model has long faced a mismatch in wave dynamics: efficient 2D wave models used in graphics are typically either linear or non-dispersive. These models are fast, simple, ...

We present a thin-shell energy formulation rigorously derived from first volumetric principles of 3D solid mechanics, overcoming limitations of prior methods that rely on geometric heuristics or restrictive assumptions such as those in Kirchhoff-Love shells. Our approach supports arbitrary nonlinear isotropic materials, reproduc...

This work addresses the challenges of distributing large physics-based simulations often encountered in the visual effects industry. These simulations, based on partial differential equations, model complex phenomena such as free surface liquids, flames, and explosions, and are characteri...

We introduce a simulation method for point vortices on surfaces with arbitrary topology. We show that incorporating the dynamics of the harmonic components on a non-simply-connected surface is equivalent to introducing a new fluid invariant that is conserved over time. This invariant admits an elegant formulation in terms of...
