Oleksiy Busaryev, Tamal Dey, Huamin Wang, Ren Zhong Bubbles and foams are important features of liquid surface phenomena, but they are difficult to animate due to their thin films and complex interactions in the real world. In particular, small bubbles … Continue reading →

Doyub Kim, Seung Woo Lee, Oh-young Song, Hyeong-Seok Ko The explosive or volcanic scenes in motion pictures involve complex turbulent flow as its temperature and density vary in space. To simulate this turbulent flow of an inhomogeneous fluid, we propose … Continue reading →

Efficient and scalable simulation of solids and fluids – Jonathan Su, Stanford  

Catching up on a collection I had never assembled… Langevin Particle: A Self-Adaptive Lagrangian Primitive for Flow Simulation Enhancement STAR: Interactive Character Animation using Simulated Physics

Melina Skouras, Bernhard Thomaszewski, Bernd Bickel, Markus Gross This paper presents an automatic process for fabrication-oriented design of custom-shaped rubber balloons. We cast computational balloon design as an inverse problem: given a target shape, we compute an optimal balloon that, … Continue reading →

Florence Bertails-Descoubes Piecewise clothoids are 2D curves with continuous, piecewise linear curvature. Due to their smoothness properties, they have been extensively used in road design and robot path planning, as well as for the compact representation of hand-drawn curves. In … Continue reading →

Ke-Sen’s steadily growing list of SIGGRAPH 2012 papers is here. Below is the subset of physics-based animation papers… SIGGRAPH papers: Continuous Penalty Forces Energy-Based Self-Collision Culling for Arbitrary Mesh Deformations Discrete Viscous Sheets Animating Bubble Interactions in a Liquid Foam … Continue reading →

Min Tang, Dinesh Manocha, Miguel Otaduy, Ruofeng Tong We present a simple algorithm to compute continuous penalty forces to determine collision response between rigid and deformable models bounded by triangle meshes. Our algorithm provides a well-behaved solution in contrast to … Continue reading →

Tyler de Witt, Christian Lessig, Eugene Fiume We present an algorithm for the simulation of incompressible fluid phenomena that is computationally efficient and leads to visually convincing simulations with far fewer degrees of freedom than existing approaches. Rather than using … Continue reading →

Florian Hecht, Yeon Jin Lee, Jonathan Shewchuk, James O’Brien We present warp-canceling corotation, a nonlinear finite element formulation for elastodynamic simulation that achieves fast performance by making only partial or delayed changes to the simulation’s linearized system matrices. Coupled with … Continue reading →
