Bijective Composite Mean Value Mappings
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We introduce the novel concept of composite barycentric mappings and give theoretical conditions under which they are guaranteed to be bijective. We then focus on mean value mappings and derive a simple procedure for ... -
Locally Injective Mappings
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Mappings and deformations are ubiquitous in geometry processing, shape modeling, and animation. Numerous deformation energies have been proposed to tackle problems like mesh parameterization and volumetric deformations. ... -
Sparse Iterative Closest Point
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Rigid registration of two geometric data sets is essential in many applications, including robot navigation, surface reconstruction, and shape matching. Most commonly, variants of the Iterative Closest Point (ICP) algorithm ... -
Fitting Polynomial Volumes to Surface Meshes with Voronoï Squared Distance Minimization
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We propose a method for mapping polynomial volumes. Given a closed surface and an initial template volume grid, our method deforms the template grid by fitting its boundary to the input surface while minimizing a volume ... -
Fast and Robust Approximation of Smallest Enclosing Balls in Arbitrary Dimensions
(The Eurographics Association and Blackwell Publishing Ltd., 2013)In this paper, an algorithm is introduced that computes an arbitrarily fine approximation of the smallest enclosing ball of a point set in any dimension. This operation is important in, for example, classification, clustering, ... -
Approximating Functions on a Mesh with Restricted Voronoï Diagrams
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We propose a method that computes a piecewise constant approximation of a function defined on a mesh. The approximation is associated with the cells of a restricted Voronoï diagram. Our method optimizes an objective function ... -
Practical Anisotropic Geodesy
(The Eurographics Association and Blackwell Publishing Ltd., 2013)The computation of intrinsic, geodesic distances and geodesic paths on surfaces is a fundamental low-level building block in countless Computer Graphics and Geometry Processing applications. This demand led to the development ... -
Discrete Line Congruences for Shading and Lighting
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Two-parameter families of straight lines (line congruences) are implicitly present in graphics and geometry processing in several important ways including lighting and shape analysis. In this paper we make them accessible ... -
An Operator Approach to Tangent Vector Field Processing
(The Eurographics Association and Blackwell Publishing Ltd., 2013)In this paper, we introduce a novel coordinate-free method for manipulating and analyzing vector fields on discrete surfaces. Unlike the commonly used representations of a vector field as an assignment of vectors to the ... -
Connectivity Editing for Quad-Dominant Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We propose a connectivity editing framework for quad-dominant meshes. In our framework, the user can edit the mesh connectivity to control the location, type, and number of irregular vertices (with more or fewer than four ... -
Weak Convex Decomposition by Lines-of-sight
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We define the convexity rank of a set of points to be the portion of mutually visible pairs of points out of the total number of pairs. Based on this definition of weak convexity, we introduce a spectral method that ... -
Semantizing Complex 3D Scenes using Constrained Attribute Grammars
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We propose a new approach to automatically semantize complex objects in a 3D scene. For this, we define an expressive formalism combining the power of both attribute grammars and constraint. It offers a practical conceptual ... -
PHOG: Photometric and Geometric Functions for Textured Shape Retrieval
(The Eurographics Association and Blackwell Publishing Ltd., 2013)In this paper we target the problem of textured 3D object retrieval. As a first contribution, we show how to include photometric information in the persistence homology setting, also proposing a novel theoretical result ... -
Shape Matching via Quotient Spaces
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We introduce a novel method for non-rigid shape matching, designed to address the symmetric ambiguity problem present when matching shapes with intrinsic symmetries. Unlike the majority of existing methods which try to ... -

Generating Pointillism Paintings Based on Seurat's Color Composition
(The Eurographics Association and Blackwell Publishing Ltd., 2013)This paper presents a novel example-based stippling technique that employs a simple and intuitive concept to convert a color image into a pointillism painting. Our method relies on analyzing and imitating the color ... -
Optimizing Disparity for Motion in Depth
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Beyond the careful design of stereo acquisition equipment and rendering algorithms, disparity post-processing has recently received much attention, where one of the key tasks is to compress the originally large disparity ... -
Interactive Lighting Design with Hierarchical Light Representation
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Lighting design plays a crucial role in indoor lighting design, computer cinematograph and many other applications. Computer-assisted lighting design aims to find a lighting configuration that best approximates the ... -
Sorted Deferred Shading for Production Path Tracing
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Ray-traced global illumination (GI) is becoming widespread in production rendering but incoherent secondary ray traversal limits practical rendering to scenes that fit in memory. Incoherent shading also leads to intractable ... -
Factorized Point Based Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd., 2013)The Point-Based Global Illumination (PBGI) algorithm is composed of two major steps: a caching step and a multiview rasterization step. At caching time, a dense point-sampling of the scene is shaded and organized in a ...
