Dynapack: Space-Time compression of the 3D animations of triangle meshes with fixed connectivity
(The Eurographics Association, 2003)Dynapack exploits space-time coherence to compress the consecutive frames of the 3D animations of triangle meshes of constant connectivity. Instead of compressing each frame independently (space-only compression) or ... -
Construction and Animation of Anatomically Based Human Hand Models
(The Eurographics Association, 2003)The human hand is a masterpiece of mechanical complexity, able to perform fine motor manipulations and powerful work alike. Designing an animatable human hand model that features the abilities of the archetype created by ... -
Visual Simulation of Ice Crystal Growth
(The Eurographics Association, 2003)The beautiful, branching structure of ice is one of the most striking visual phenomena of the winter landscape. Yet there is little study about modeling this effect in computer graphics. In this paper, we present a novel ... -
Discrete Shells
(The Eurographics Association, 2003)In this paper we introduce a discrete shell model describing the behavior of thin flexible structures, such as hats, leaves, and aluminum cans, which are characterized by a curved undeformed configuration. Previously such ... -
Blowing in the Wind
(The Eurographics Association, 2003)We present an approach for simulating the natural dynamics that emerge from the coupling of a flow field to lightweight, mildly deformable objects immersed within it. We model the flow field using a Lattice Boltzmann Model ... -
Finite Volume Methods for the Simulation of Skeletal Muscle
(The Eurographics Association, 2003)Since it relies on a geometrical rather than a variational framework, many find the finite volume method (FVM) more intuitive than the finite element method (FEM).We show that the FVM allows one to interpret the stress ... -
Estimating Cloth Simulation Parameters from Video
(The Eurographics Association, 2003)Cloth simulations are notoriously difficult to tune due to the many parameters that must be adjusted to achieve the look of a particular fabric. In this paper, we present an algorithm for estimating the parameters of a ... -
Feel the 'Fabric': An Audio-Haptic Interface
(The Eurographics Association, 2003)An objective fabric modeling system should convey not only the visual but also the haptic and audio sensory feedbacks to remote/internet users via an audio-haptic interface. In this paper we develop a fabric surface property ... -
Interactive Physically Based Solid Dynamics
(The Eurographics Association, 2003)The interactive simulation of deformable solids has become a major working area in Computer Graphics. We present a sophisticated material law, better suited for dynamical computations than the standard approaches. As an ... -
Simulation of Clothing with Folds and Wrinkles
(The Eurographics Association, 2003)Clothing is a fundamental part of a character's persona, a key storytelling tool used to convey an intended impression to the audience. Draping, folding, wrinkling, stretching, etc. all convey meaning, and thus each is ... -
A Practical Dynamics System
(The Eurographics Association, 2003)We present an effective production-proven dynamics system. It uses an explicit time differencing method that is efficient, reasonably accurate, conditionally stable, and above all simple to implement. We describe issues ... -
Perceptual evaluation of footskate cleanup
(The Eurographics Association, 2011)When animating virtual humans for real-time applications such as games and virtual reality, animation systems often have to edit motions in order to be responsive. In many cases, contacts between the feet and the ground ... -
Spacetime Vertex Constraints for Dynamically-based Adaptation of Motion-Captured Animation
(The Eurographics Association, 2011)We present a novel technique for editing motion captured animation. Our iterative solver produces physicallyplausible adaptated animations that satisfy alterations in foot and hand contact placement with the animated ... -
Biomechanically-Inspired Motion Path Editing
(The Eurographics Association, 2011)We present a system for interactive kinematic editing of motion paths and timing that employs various biomechanical observations to augment and restrict the edited motion. Realistic path manipulations are enforced by ... -
Element-Wise Mixed Implicit-Explicit Integration for Stable Dynamic Simulation of Deformable Objects
(The Eurographics Association, 2011)In order to evolve a deformable object in time, the underlying equations of motion have to be numerically integrated. This is commonly done by employing either an explicit or an implicit integration scheme. While explicit ... -
Asynchronous Integration with Phantom Meshes
(The Eurographics Association, 2011)Asynchronous variational integration of layered contact models provides a framework for robust collision handling, correct physical behavior, and guaranteed eventual resolution of even the most difficult contact problems. ... -
Robust Real-Time Deformation of Incompressible Surface Meshes
(The Eurographics Association, 2011)We introduce an efficient technique for robustly simulating incompressible objects with thousands of elements in real-time. Instead of considering a tetrahedral model, commonly used to simulate volumetric bodies, we simply ... -
Optimization for Sag-Free Simulations
(The Eurographics Association, 2011)A common problem during the first few seconds of a cloth, hair, or flesh simulation is that the mesh sags under gravity, which can undo the work of hours of careful modeling. The typical response of increasing the stiffness ... -
Real-time Facial Animation from Live Video Tracking
(The Eurographics Association, 2011)This paper describes a complete pipe-line of a practical system for producing real-time facial expressions of a 3D virtual avatar controlled by an actor's live performances. The system handles practical challenges arising ... -
Facial Cartography: Interactive Scan Correspondence
(The Eurographics Association, 2011)We present a semi-automatic technique for computing surface correspondences between 3D facial scans in different expressions, such that scan data can be mapped into a common domain for facial animation. The technique can ...
