Soft Articulated Characters with Fast Contact Handling
(The Eurographics Association and Blackwell Publishing Ltd, 2007)Fast contact handling of soft articulated characters is a computationally challenging problem, in part due to complex interplay between skeletal and surface deformation. We present a fast, novel algorithm based on a layered ... -
Skeleton-based Variational Mesh Deformations
(The Eurographics Association and Blackwell Publishing Ltd, 2007)In this paper, a new free-form shape deformation approach is proposed. We combine a skeleton-based mesh deformation technique with discrete differential coordinates in order to create natural-looking global shape deformations. ... -
Serious Games: Broadening Games Impact Beyond Entertainment
(The Eurographics Association and Blackwell Publishing Ltd, 2007)Computer and videogames for many years has been an island of technology and design innovation largely left to itself as it morphed from a cottage business into a global media and software industry. While there have been ... -
Reverse Engineering Nature
(The Eurographics Association and Blackwell Publishing Ltd, 2007)Why is the sky blue? Why is grass green? What determines the color of human skin? Questions such as these are increasingly important in the development of the next generation algorithms for appearancemodeling in computer ... -
Layered Performance Animation with Correlation Maps
(The Eurographics Association and Blackwell Publishing Ltd, 2007)Performance has a spontaneity and aliveness that can be difficult to capture in more methodical animation processes such as keyframing. Access to performance animation has traditionally been limited to either low degree ... -
Pedestrian Reactive Navigation for Crowd Simulation: a Predictive Approach
(The Eurographics Association and Blackwell Publishing Ltd, 2007)This paper addresses the problem of virtual pedestrian autonomous navigation for crowd simulation. It describes a method for solving interactions between pedestrians and avoiding inter-collisions. Our approach is agent-based ... -
Crowds by Example
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We present an example-based crowd simulation technique. Most crowd simulation techniques assume that the behavior exhibited by each person in the crowd can be defined by a restricted set of rules. This assumption limits ... -
Depth-of-Field Rendering by Pyramidal Image Processing
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We present an image-based algorithm for interactive rendering depth-of-field effects in images with depth maps. While previously published methods for interactive depth-of-field rendering suffer from various rendering ... -
Texturing Internal Surfaces from a Few Cross Sections
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We introduce a new appearance-modeling paradigm for synthesizing the internal structure of a 3D model from photographs of a few cross-sections of a real object. When the internal surfaces of the 3D model are revealed as ... -
Mesh Segmentation via Spectral Embedding and Contour Analysis
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We propose a mesh segmentation algorithm via recursive bisection where at each step, a sub-mesh embedded in 3D is first spectrally projected into the plane and then a contour is extracted from the planar embedding. We rely ... -
Stackless KD-Tree Traversal for High Performance GPU Ray Tracing
(The Eurographics Association and Blackwell Publishing Ltd, 2007)Significant advances have been achieved for realtime ray tracing recently, but realtime performance for complex scenes still requires large computational resources not yet available from the CPUs in standard PCs. Incidentally, ... -
A Finite Element Method on Convex Polyhedra
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We present a method for animating deformable objects using a novel finite element discretization on convex polyhedra. Our finite element approach draws upon recently introduced 3D mean value coordinates to define smooth ... -
Ray-Casted BlockMaps for Large Urban Models Visualization
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We introduce a GPU-friendly technique that efficiently exploits the highly structured nature of urban environments to ensure rendering quality and interactive performance of city exploration tasks. Central to our approach ... -
QuadCover - Surface Parameterization using Branched Coverings
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We introduce an algorithm for the automatic computation of global parameterizations on arbitrary simplicial 2-manifolds, whose parameter lines are guided by a given frame field, for example, by principal curvature frames. ... -
Highly Parallel Fast KD-tree Construction for Interactive Ray Tracing of Dynamic Scenes
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We present a highly parallel, linearly scalable technique of kd-tree construction for ray tracing of dynamic geometry. We use conventional kd-tree compatible with the high performing algorithms such as MLRTA or frustum ... -
Adaptive Space Deformations Based on Rigid Cells
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We propose a new adaptive space deformation method for interactive shape modeling. A novel energy formulation based on elastically coupled volumetric cells yields intuitive detail preservation even under large deformations. ... -
Geodesic-Controlled Developable Surfaces for Modeling Paper Bending
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We present a novel and effective method for modeling a developable surface to simulate paper bending in interactive and animation applications. The method exploits the representation of a developable surface as the envelope ... -
Real-Time Simulation of Thin Shells
(The Eurographics Association and Blackwell Publishing Ltd, 2007)This paper proposes a real-time simulation technique for thin shells undergoing large deformation. Shells are thin objects such as leaves and papers that can be abstracted as 2D structures. Development of a satisfactory ... -
Global Illumination using Photon Ray Splatting
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We present a novel framework for efficiently computing the indirect illumination in diffuse and moderately glossy scenes using density estimation techniques. Many existing global illumination approaches either quickly ... -
Markerless 4 gestures 6 DOF real-time visual tracking of the human hand with automatic initialization
