Christopher Batty, Andres Uribe, Basile Audoly, Eitan Grinspun We present the first reduced-dimensional technique to simulate the dynamics of thin sheets of viscous incompressible liquid in three dimensions. Beginning from a discrete Lagrangian model for elastic thin shells, we apply … Continue reading →

Changsoo Je, Min Tang, Youngeun Lee, Minkyoung Lee, Young J. Kim We present a real-time algorithm that finds the Penetration Depth (PD) between general polygonal models based on iterative and local optimization techniques. Given an in-collision configuration of an object … Continue reading →

Ondrej Stava, Juraj Vanek, Bedrich Benes, Nathan Carr, Radomir Mech 3D printing is a rapidly maturing area that has shown great progress over the past couple of years. It is now possible to produce 3D printed objects with exceptionally high fidelity and precision. However, … Continue reading →

Steffen Weissman, Ulrich Pinkall We show that the motion of rigid bodies under water can be realistically simulated by replacing the usual inertia tensor and scalar mass by the so-called Kirchhoff tensor. This allows us to model fluid-body interaction without … Continue reading →

Tobias Pfaff, Nils Thuerey, Markus Gross Buoyant turbulent smoke plumes with a sharp smoke-air interface, such as volcanic plumes, are notoriously hard to simulate. The surface clearly shows small-scale turbulent structures which are costly to resolve. In addition, the turbulence … Continue reading →

Hagit Schechter, Robert Bridson We propose a new ghost fluid approach for free surface and solid boundary conditions in Smoothed Particle Hydrodynamics (SPH) liquid simulations. Prior methods either suffer from a spurious numerical surface tension artifact or drift away from … Continue reading →
