Image-based Collision Detection and Response between Arbitrary Volume Objects
(The Eurographics Association, 2008)
We present a new image-based method to process contacts between objects bounded by triangular surfaces. Unlike previous methods, it relies on image-based volume minimization, which eliminates complex geometrical computations ...
Action Capture with Accelerometers
(The Eurographics Association, 2008)
We create a performance animation system that leverages the power of low-cost accelerometers, readily available motion capture databases, and construction techniques from e-textiles. Our system, built with only off-theshelf ...
Composite Agents
(The Eurographics Association, 2008)
We introduce the concept of composite agents to effectively model complex agent interactions for agent-based crowd simulation. Each composite agent consists of a basic agent that is associated with one or more proxy agents. ...
Evolving Sub-Grid Turbulence for Smoke Animation
(The Eurographics Association, 2008)
We introduce a simple turbulence model for smoke animation, qualitatively capturing the transport, diffusion, and spectral cascade of turbulent energy unresolved on a typical simulation grid. We track the mean kinetic ...
Meshless Modeling of Deformable Shapes and their Motion
(The Eurographics Association, 2008)
We present a new framework for interactive shape deformation modeling and key frame interpolation based on a meshless finite element formulation. Starting from a coarse nodal sampling of an object's volume, we formulate ...
Staggered Poses: A Character Motion Representation for Detail-Preserving Editing of Pose and Coordinated Timing
(The Eurographics Association, 2008)
We introduce staggered poses - a representation of character motion that explicitly encodes coordinated timing among movement features in different parts of a character's body. This representation allows us to provide ...
Low Viscosity Flow Simulations for Animation
(The Eurographics Association, 2008)
We present a combination of techniques to simulate turbulent fluid flows in 3D. Flow in a complex domain is modeled using a regular rectilinear grid with a finite-difference solution to the incompressible Navier-Stokes ...
Perceptually Guided Expressive Facial Animation
(The Eurographics Association, 2008)
Most of current facial animation approaches largely focus on the accuracy or efficiency of their algorithms, or how to optimally utilize pre-collected facial motion data. However, human perception, the ultimate measuring ...
Puppet Master: Designing Reactive Character Behavior by Demonstration
(The Eurographics Association, 2008)
Puppet Master is a system that enables designers to rapidly create interactive and autonomous animated character behaviors that react to a main character controlled by an end-user. The behavior is designed by demonstration, ...
Pose-Space Animation and Transfer of Facial Details
(The Eurographics Association, 2008)
This paper presents a novel method for real-time animation of highly-detailed facial expressions based on a multi-scale decomposition of facial geometry into large-scale motion and fine-scale details, such as expression ...
