Leveraging the Talent of Hand Animators to Create Three-Dimensional Animation
(ACM SIGGRAPH / Eurographics Association, 2009)
The skills required to create compelling three-dimensional animation using computer software are quite different from those required to create compelling hand animation with pencil and paper. The three-dimensional medium ...
Statistical Simulation of Rigid Bodies
(ACM SIGGRAPH / Eurographics Association, 2009)
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 ...
Accurate Tangential Velocities For Solid Fluid Coupling
(ACM SIGGRAPH / Eurographics Association, 2009)
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 ...
Bounded Normal Trees for Reduced Deformations of Triangulated Surfaces
(ACM SIGGRAPH / Eurographics Association, 2009)
Several reduced deformation models in computer animation, such as linear blend skinning, point-based animation, embedding in finite element meshes, cage-based deformation, or subdivision surfaces, define surface vertex ...

A Point-based Method for Animating Incompressible Flow
(ACM SIGGRAPH / Eurographics Association, 2009)
In this paper, we present a point-based method for animating incompressible flow. The advection term is handled by moving the sample points through the flow in a Lagrangian fashion. However, unlike most previous approaches, ...
Real-Time Deformation and Fracture in a Game Environment
(ACM SIGGRAPH / Eurographics Association, 2009)
This paper describes a simulation system that has been developed to model the deformation and fracture of solid objects in a real-time gaming context. Based around a corotational tetrahedral finite element method, this ...
Visibility Transition Planning for Dynamic Camera Control
(ACM SIGGRAPH / Eurographics Association, 2009)
We present a real-time camera control system that uses a global planning algorithm to compute large, occlusion free camera paths through complex environments. The algorithm incorporates the visibility of a focus point into ...
Energy Stability and Fracture for Frame Rate Rigid Body Simulations
(ACM SIGGRAPH / Eurographics Association, 2009)
Our goal is to design robust algorithms that can be used for building real-time systems, but rather than starting with overly simplistic particle-based methods, we aim to modify higher-end visual effects algorithms. A major ...
Simulating Balance Recovery Responses to Trips Based on Biomechanical Principles
(ACM SIGGRAPH / Eurographics Association, 2009)
To realize the full potential of human simulations in interactive environments, we need controllers that have the ability to respond appropriately to unexpected events. In this paper, we create controllers for the trip ...
