Expression Synthesis and Transfer in Parameter Spaces
(The Eurographics Association and Blackwell Publishing Ltd, 2009)In this paper, we introduce a novel framework that allows users to synthesize the expression of a 3D character by providing a intuitive set of parametric controls. Assuming that human face movements are formed by a set of ... -
ProcDef: Local-to-global Deformation for Skeleton-free Character Animation
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Animations of characters with flexible bodies such as jellyfish, snails, and, hearts are difficult to design using traditional skeleton-based approaches. A standard approach is keyframing, but adjusting the shape of the ... -
Procedural Generation of Rock Piles using Aperiodic Tiling
(The Eurographics Association and Blackwell Publishing Ltd, 2009)In this paper, we present a tiling method for generating piles of rocks without any computationally demanding physically-based simulation. Previous techniques rely on a periodic tiling of rocks and generate unrealistic ... -
Affective Modelling: Profiling Geometrical Models with Human Emotional Responses
(The Eurographics Association and Blackwell Publishing Ltd, 2009)In this paper, a novel concept, Affective Modelling, is introduced to encapsulate the idea of creating 3D models based on the emotional responses that they may invoke. Research on perceptually-related issues in Computer ... -
HPCCD: Hybrid Parallel Continuous Collision Detection using CPUs and GPUs
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a novel, hybrid parallel continuous collision detection (HPCCD) method that exploits the availability of multi-core CPU and GPU architectures. HPCCD is based on a bounding volume hierarchy (BVH) and selectively ... -
Approximate on-Surface Distance Computation using Quasi-Developable Charts
(The Eurographics Association and Blackwell Publishing Ltd, 2009)There is a vast number of applications that require distance field computation over triangular meshes. State-of-the-art algorithms have quadratic or sub-quadratic worst-case complexity, making them impractical for interactive ... -
Linkless Octree Using Multi-Level Perfect Hashing
(The Eurographics Association and Blackwell Publishing Ltd, 2009)The standard C/C++ implementation of a spatial partitioning data structure, such as octree and quadtree, is often inefficient in terms of storage requirements particularly when the memory overhead for maintaining parent-to-child ... -
An Intuitive Interface for Interactive High Quality Image-Based Modeling
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present the design of an interactive image-based modeling tool that enables a user to quickly generate detailed 3D models with texture from a set of calibrated input images. Our main contribution is an intuitive user ... -
Image-to-Geometry Registration: a Mutual Information Method exploiting Illumination-related Geometric Properties
(The Eurographics Association and Blackwell Publishing Ltd, 2009)This work concerns a novel study in the field of image-to-geometry registration. Our approach takes inspiration from medical imaging, in particular from multi-modal image registration. Most of the algorithms developed in ... -
Live Video Montage with a Rotating Camera
(The Eurographics Association and Blackwell Publishing Ltd, 2009)High-quality video editing usually requires accurate layer separation in order to resolve occlusions. However, most of the existing bilayer segmentation algorithms require either considerable user intervention or a simple ... -
SecondSkin: An interactive method for appearance transfer
(The Eurographics Association and Blackwell Publishing Ltd, 2009)SecondSkin estimates an appearance model for an object visible in a video sequence, without the need for complex interaction or any calibration apparatus. This model can then be transferred to other objects, allowing a ... -
Frontmatter and Cover

Separatrix Persistence: Extraction of Salient Edges on Surfaces Using Topological Methods
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Salient edges are perceptually prominent features of a surface. Most previous extraction schemes utilize the notion of ridges and valleys for their detection, thereby requiring curvature derivatives which are rather sensitive ... -
Estimating the Laplace-Beltrami Operator by Restricting 3D Functions
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a novel approach for computing and solving the Poisson equation over the surface of a mesh. As in previous approaches, we define the Laplace-Beltrami operator by considering the derivatives of functions defined ... -
Discrete Critical Values: a General Framework for Silhouettes Computation
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Many shapes resulting from important geometric operations in industrial applications such as Minkowski sums or volume swept by a moving object can be seen as the projection of higher dimensional objects. When such a higher ... -
Approximating Gradients for Meshes and Point Clouds via Diffusion Metric
(The Eurographics Association and Blackwell Publishing Ltd, 2009)The gradient of a function defined on a manifold is perhaps one of the most important differential objects in data analysis. Most often in practice, the input function is available only at discrete points sampled from the ... -
Stability of Curvature Measures
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We address the problem of curvature estimation from sampled compact sets. The main contribution is a stability result: we show that the Gaussian, mean or anisotropic curvature measures of the offset of a compact set K with ... -
Filtering Relocations on a Delaunay Triangulation
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Updating a Delaunay triangulation when its vertices move is a bottleneck in several domains of application. Rebuilding the whole triangulation from scratch is surprisingly a very viable option compared to relocating the ... -
Feature preserving Delaunay mesh generation from 3D multi-material images
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Generating realistic geometric models from 3D segmented images is an important task in many biomedical applications. Segmented 3D images impose particular challenges for meshing algorithms because they contain multi-material ... -
Isotropic Remeshing with Fast and Exact Computation of Restricted Voronoi Diagram
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We propose a new isotropic remeshing method, based on Centroidal Voronoi Tessellation (CVT). Constructing CVT requires to repeatedly compute Restricted Voronoi Diagram (RVD), defined as the intersection between a 3D Voronoi ...
