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 ... -
Markerless 4 gestures 6 DOF real-time visual tracking of the human hand with automatic initialization
(The Eurographics Association and Blackwell Publishing Ltd, 2007)In this paper we present a novel computer vision based hand-tracking technique, which is capable of robustly tracking 6+4DOF of the human hand in real-time (at least 25 frames per second) with the help of 3 (or more) ... -
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 ... -
Metropolis Instant Radiosity
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We present Metropolis Instant Radiosity (MIR), an unbiased algorithm to solve the Light Transport problem. MIR is a hybrid technique which consists in representing the incoming radiance field by a set of Virtual Point ... -
Omni-directional Relief Impostors
(The Eurographics Association and Blackwell Publishing Ltd, 2007)Relief impostors have been proposed as a compact and high-quality representation for high-frequency detail in 3D models. In this paper we propose an algorithm to represent a complex object through the combination of a ... -
On-the-fly Curve-skeleton Computation for 3D Shapes
(The Eurographics Association and Blackwell Publishing Ltd, 2007)The curve-skeleton of a 3D object is an abstract geometrical and topological representation of its 3D shape. It maps the spatial relation of geometrically meaningful parts to a graph structure. Each arc of this graph ... -
Online Motion Capture Marker Labeling for Multiple Interacting Articulated Targets
(The Eurographics Association and Blackwell Publishing Ltd, 2007)In this paper, we propose an online motion capture marker labeling approach for multiple interacting articulated targets. Given hundreds of unlabeled motion capture markers from multiple articulated targets that are ... -
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 ... -
Precomputed Radiance Transfer Field for Rendering Interreflections in Dynamic Scenes
(The Eurographics Association and Blackwell Publishing Ltd, 2007)In this paper, we introduce a new representation - radiance transfer fields (RTF) - for rendering interreflections in dynamic scenes under low frequency illumination. The RTF describes the radiance transferred by an ... -
Prediction of Individual Non-Linear Aging Trajectories of Faces
(The Eurographics Association and Blackwell Publishing Ltd, 2007)Represented in a Morphable Model, 3D faces follow curved trajectories in face space as they age. We present a novel algorithm that computes the individual aging trajectories for given faces, based on a non-linear function ... -
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. ... -
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 ... -
Real-time homogenous translucent material editing
(The Eurographics Association and Blackwell Publishing Ltd, 2007)This paper presents a novel method for real-time homogenous translucent material editing under fixed illumination. We consider the complete analytic BSSRDF model proposed by Jensen et al. [JMLH01], including both multiple ... -
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 ... -
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 ... -
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 ... -
Shape-aware Volume Illustration
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We introduce a novel volume illustration technique for regularly sampled volume datasets. The fundamental difference between previous volume illustration algorithms and ours is that our results are shape-aware, as they ... -
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. ... -
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 ... -
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, ...
