Parallel Particles (P^2): A Parallel Position Based Approach for Fast and Stable Simulation of Granular Materials

Posted on September 30, 2014 by christopherbatty

Daniel Holz Granular materials exhibit a large number of diverse physical phenomena which makes their numerical simulation challenging. When set in motion they flow almost like a fluid, while they can present high shear strength when at rest. Those macroscopic … Continue reading →

Stylized Keyframe Animation of Fluid Simulations

Posted on September 27, 2014 by christopherbatty

Mark Browning, Connelly Barnes, Samantha Ritter, Adam Finkelstein We present a method that combines hand-drawn artwork with fluid simulations to produce animated fluids in the visual style of the artwork. Given a fluid simulation and a set of keyframes rendered by … Continue reading →

Particle-particle Particle-mesh (PPPM) Fast Summation for Fluids and Beyond

Posted on September 24, 2014 by christopherbatty

Xinxin Zhang, Robert Bridson Solving the N-body problem, i.e. the Poisson problem with point sources, is a common task in graphics and simulation. The naive direct summation of the kernel function over all particles scales quadratically, rendering it too slow for … Continue reading →

Animation of Deformable Bodies with Quadratic Bézier Finite Elements

Posted on September 15, 2014 by christopherbatty

Adam W. Bargteil, Elaine Cohen In this paper, we investigate the use of quadratic finite elements for graphical animation of deformable bodies. We consider both integrating quadratic elements with conventional linear elements to achieve a computationally efficient adaptive-degree simulation framework … Continue reading →

Continuous Collision Detection Between Points and Signed Distance Fields

Posted on September 13, 2014 by christopherbatty

Hongyi Xu, Jernej Barbic We present an algorithm for fast continuous collision detection between points and signed distance fields. Such robust queries are often needed in computer animation, haptics and virtual reality applications, but have so far only been investigated … Continue reading →
