SCA 2009 Papers

The list of papers from the 2009 Symposium on Computer Animation have been up for a while at Ke-Sen Huang’s page. Here’s the subset that fall most directly under physics-based animation: A Point-based Method for Animating Elastoplastic Solids Statistical Simulation of Rigid Bodies Anisotropic Friction for Deformable Surfaces and Solids Energy Stability and Fracture for […]

Statistical Simulation of Rigid Bodies

We describe a method for replacing certain stages of rigid body simulation with a statistically-based approximation. We begin by collecting statistical data regarding changes in linear and angular momentum for collisions of a given object. From this data we extract a statistical “signature” for the object, giving a compact representation of the object’s response to […]

Fluid Simulation with Articulated Bodies

We present an algorithm for creating realistic animations of characters that are swimming through fluids. Our approach combines dynamic simulation with data-driven kinematic motions (motion capture data) to produce realistic animation in a fluid. The interaction of the articulated body with the fluid is performed by incorporating joint constraints with rigid animation and by extending […]

Anisotropic Friction for Deformable Surfaces and Solids

This paper presents a method for simulating anisotropic friction for deforming surfaces and solids. Frictional contact is a complex phenomenon that fuels research in mechanical engineering, computational contact mechanics, composite material design and rigid body dynamics, to name just a few. Many real-world materials have anisotropic surface properties. As an example, most textile materials exhibit […]

Accurate Tangential Velocities for Solid-Fluid Coupling

We propose a novel method for obtaining more accurate tangential velocities for solid fluid coupling. Our method works for both rigid and deformable objects as well as both volumetric objects and thin shells. The fluid can be either one phase such as smoke or two phase such as water with a free surface. The coupling […]
