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 ... -
Achieving Good Connectivity in Motion Graphs
(The Eurographics Association, 2008)Motion graphs provide users with a simple yet powerful way to synthesize human motions. While motion graphbased synthesis has been widely successful, the quality of the generatedmotion depends largely on the connectivity ... -
Motion-Motif Graphs
(The Eurographics Association, 2008)We present a technique to automatically distill a motion-motif graph from an arbitrary collection of motion capture data. Motion motifs represent clusters of similar motions and together with their encompassing motion graph ... -
Elevation Cable Modeling for Interactive Simulation of Cranes
(The Eurographics Association, 2008)In this paper, the way to simulate hoisting cables in real time is addressed. We overcome instability in such simulation by considering a two-layered model: a model for the dynamics of a cable passing through a set of ... -
Real-Time Planning for Parameterized Human Motion
(The Eurographics Association, 2008)We present a novel approach to learn motion controllers for real-time character animation based on motion capture data. We employ a tree-based regression algorithm for reinforcement learning, which enables us to generate ... -
Interactive Terrain Modeling Using Hydraulic Erosion
(The Eurographics Association, 2008)We present a step toward interactive physics-based modeling of terrains. A terrain, composed of layers of materials, is edited with interactive modeling tools built upon different physics-based erosion and deposition ... -
Visual Simulation of Shockwaves
(The Eurographics Association, 2008)We present an efficient method for visual simulations of shock phenomena in compressible, inviscid fluids. Our algorithm is derived from one class of the finite volume method especially designed for capturing shock ... -
Globally Coupled Collision Handling Using Volume Preserving Impulses
(The Eurographics Association, 2008)We present a novel algorithm for collision processing on triangulated meshes. Our method robustly maintains a collision free state on complex geometries while resorting to collision resolution at time intervals often ... -
Fast Adaptive Shape Matching Deformations
(The Eurographics Association, 2008)We present a new shape-matching deformation model that allows for efficient handling of topological changes and dynamic adaptive selection of levels of detail. Similar to the recently presented Fast Lattice Shape Matching ... -
Synthesis of Interactive Hand Manipulation
(The Eurographics Association, 2008)We present an interactive physics-based motion synthesis technique for creating hand manipulation across a wide variety of tasks, objects, user interventions, and stylistic preferences. Given an object being manipulated, ... -
Flexible Simulation of Deformable Models Using Discontinuous Galerkin FEM
(The Eurographics Association, 2008)We propose a simulation technique for elastically deformable objects based on the discontinuous Galerkin finite element method (DG FEM). In contrast to traditional FEM, it overcomes the restrictions of conforming basis ...
