Adaptive Deformations with Fast Tight Bounds
(The Eurographics Association, 2007)Simulation of deformations and collision detection are two highly intertwined problems that are often treated sepa- rately. This is especially true in existing elegant adaptive simulation techniques, where standard collision ... -
Animation Collage
(The Eurographics Association, 2007)We propose a method to automatically transform mesh animations into animation collages, i.e. moving assemblies of shape primitives from a database given by an artist. An animation collage is a complete reassembly of the ... -
Animation of Chemically Reactive Fluids Using a Hybrid Simulation Method
(The Eurographics Association, 2007)Chemical phenomena abound in the real world, and often comprise indispensable elements of visual effects that are routinely created in the film industry. In this paper, we present a hybrid technique for simulating chemically ... -
Arbitrary Cutting of Deformable Tetrahedralized Objects
(The Eurographics Association, 2007)We propose a flexible geometric algorithm for placing arbitrary cracks and incisions on tetrahedralized deformable objects. Although techniques based on remeshing can also accommodate arbitrary fracture patterns, this ... -
Controlling Individual Agents in High-Density Crowd Simulation
(The Eurographics Association, 2007)Simulating the motion of realistic, large, dense crowds of autonomous agents is still a challenge for the computer graphics community. Typical approaches either resemble particle simulations (where agents lack orientation ... -
CORDE: Cosserat Rod Elements for the Dynamic Simulation of One-Dimensional Elastic Objects
(The Eurographics Association, 2007)Simulating one-dimensional elastic objects such as threads, ropes or hair strands is a difficult problem, especially if material torsion is considered. In this paper, we present CORDE(french rope ), a novel deformation ... -
Cubic Shells
(The Eurographics Association, 2007)Hinge-based bending models are widely used in the physically-based animation of cloth, thin plates and shells. We propose a hinge-based model that is simpler to implement, more efficient to compute, and offers a greater ... -
A Decision Network Framework for the Behavioral Animation of Virtual Humans
(The Eurographics Association, 2007)We introduce a framework for advanced behavioral animation in virtual humans, which addresses the challenging open problem of simulating social interactions between pedestrians in urban settings. Based on hierarchical ... -
Deformation Styles for Spline-based Skeletal Animation
(The Eurographics Association, 2007)We present a novel skinned skeletal animation system based on spline-aligned deformations for providing high quality and fully designable deformations in real-time. Our ambition is to allow artists the easy creation of ... -
Dynamic, Expressive Speech Animation From a Single Mesh
(The Eurographics Association, 2007)In this work we present a method for human face animation which allows us to generate animations for a novel person given just a single mesh of their face. These animations can be of arbitrary text and may include emotional ... -
Face Poser: Interactive Modeling of 3D Facial Expressions Using Model Priors
(The Eurographics Association, 2007)In this paper, we present an intuitive interface for interactively posing 3D facial expressions. The user can create and edit facial expressions by drawing freeform strokes, or by directly dragging facial points in 2D ... -
Flipping with Physics: Motion Editing for Acrobatics
(The Eurographics Association, 2007)Complex acrobatic stunts, such as double or triple flips, can be performed only by highly skilled athletes. On the other hand, simpler tricks, such as single-flip jumps, are relatively easy to master.We present a method ... -
Group Behavior from Video: A Data-Driven Approach to Crowd Simulation
(The Eurographics Association, 2007)Crowd simulation techniques have frequently been used to animate a large group of virtual humans in computer graphics applications. We present a data-driven method of simulating a crowd of virtual humans that exhibit ... -
Guided TimeWarping for Motion Editing
(The Eurographics Association, 2007)Time warping allows users to modify timing without affecting poses. It has many applications in animation systems for motion editing, such as refining motions to meet new timing constraints or modifying the acting of ... -
Harmonic Skeleton for Realistic Character Animation
(The Eurographics Association, 2007)Current approaches to skeleton generation are based on topological and geometrical information only; this can be insufficient for realistic character animation, since the location of the joints does not usually match the ... -
Hybrid Simulation of Deformable Solids
(The Eurographics Association, 2007)Although mesh-based methods are efficient for simulating simple hyperelasticity, maintaining and adapting a mesh-based representation is less appealing in more complex scenarios, e.g. collision, plasticity and fracture. ... -
Kinodynamic skinning using volume-preserving deformations
(The Eurographics Association, 2007)We present a new approach to character skinning where divergence-free vector fields induced by skeletal motion, describe the velocity of skin deformation. The joint transformations for a pose relative to a rest pose create ... -
Legendre Fluids: A Unified Framework for Analytic Reduced Space Modeling and Rendering of Participating Media
(The Eurographics Association, 2007)In this paper, we present a unified framework for reduced space modeling and rendering of dynamic and non- homogenous participating media, like snow, smoke, dust and fog. The key idea is to represent the 3D spatial variation ... -
Liquid Simulation on Lattice-Based Tetrahedral Meshes
(The Eurographics Association, 2007)We describe a method for animating incompressible liquids with detailed free surfaces. For each time step, semi- Lagrangian contouring computes a new fluid boundary (represented as a fine surface triangulation) from the ... -
Multiobjective Control with Frictional Contacts
(The Eurographics Association, 2007)Standing is a fundamental skill mastered by humans and animals alike. Although easy for adults, it requires careful and deliberate manipulation of contact forces. The variation in contact configuration (e.g., standing on ...
