Geodesic Distance Computation via Virtual Source Propagation
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We present a highly practical, efficient, and versatile approach for computing approximate geodesic distances. The method is designed to operate on triangle meshes and a set of point sources on the surface. We also show ... -
Roominoes: Generating Novel 3D Floor Plans From Existing 3D Rooms
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Realistic 3D indoor scene datasets have enabled significant recent progress in computer vision, scene understanding, autonomous navigation, and 3D reconstruction. But the scale, diversity, and customizability of existing ... -
Learning Direction Fields for Quad Mesh Generation
(The Eurographics Association and John Wiley & Sons Ltd., 2021)State of the art quadrangulation methods are able to reliably and robustly convert triangle meshes into quad meshes. Most of these methods rely on a dense direction field that is used to align a parametrization from which ... -
A Benchmark Dataset for Repetitive Pattern Recognition on Textured 3D Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2021)In digital archaeology, a large research area is concerned with the computer-aided analysis of 3D captured ancient pottery objects. A key aspect thereby is the analysis of motifs and patterns that were painted on these ... -
SimJEB: Simulated Jet Engine Bracket Dataset
(The Eurographics Association and John Wiley & Sons Ltd., 2021)This paper introduces the Simulated Jet Engine Bracket Dataset (SimJEB) [WBM21]: a new, public collection of crowdsourced mechanical brackets and accompanying structural simulations. SimJEB is applicable to a wide range ... -
Stable and Efficient Differential Estimators on Oriented Point Clouds
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Point clouds are now ubiquitous in computer graphics and computer vision. Differential properties of the point-sampled surface, such as principal curvatures, are important to estimate in order to locally characterize the ... -
Practical Computation of the Cut Locus on Discrete Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We present a novel method to compute the cut locus of a distance function encoded on a polygonal mesh. Our method exploits theoretical findings about the cut locus and - with a combination of analytic, geometric and ... -
Simpler Quad Layouts using Relaxed Singularities
(The Eurographics Association and John Wiley & Sons Ltd., 2021)A common approach to automatic quad layout generation on surfaces is to, in a first stage, decide on the positioning of irregular layout vertices, followed by finding sensible layout edges connecting these vertices and ... -
Developable Approximation via Gauss Image Thinning
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Approximating 3D shapes with piecewise developable surfaces is an active research topic, driven by the benefits of developable geometry in fabrication. Piecewise developable surfaces are characterized by having a Gauss ... -

Blending of Hyperbolic Closed Curves
(The Eurographics Association and John Wiley & Sons Ltd., 2021)In recent years, game developers are interested in developing games in the hyperbolic space. Shape blending is one of the fundamental techniques to produce animation and videos games. This paper presents two algorithms for ... -
Surface Map Homology Inference
(The Eurographics Association and John Wiley & Sons Ltd., 2021)A homeomorphism between two surfaces not only defines a (continuous and bijective) geometric correspondence of points but also (by implication) an identification of topological features, i.e. handles and tunnels, and how ... -
Fabrication-Aware Reverse Engineering for Carpentry
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We propose a novel method to generate fabrication blueprints from images of carpentered items. While 3D reconstruction from images is a well-studied problem, typical approaches produce representations that are ill-suited ... -
Frame Field Operators
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Differential operators are widely used in geometry processing for problem domains like spectral shape analysis, data interpolation, parametrization and mapping, and meshing. In addition to the ubiquitous cotangent Laplacian, ... -
Scalable Surface Reconstruction with Delaunay-Graph Neural Networks
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We introduce a novel learning-based, visibility-aware, surface reconstruction method for large-scale, defect-laden point clouds. Our approach can cope with the scale and variety of point cloud defects encountered in real-life ... -
On Landmark Distances in Polygons
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We study the landmark distance function between two points in a simply connected planar polygon. We show that if the polygon vertices are used as landmarks, then the resulting landmark distance function to any given point ... -
The Diamond Laplace for Polygonal and Polyhedral Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We introduce a construction for discrete gradient operators that can be directly applied to arbitrary polygonal surface as well as polyhedral volume meshes. The main idea is to associate the gradient of functions defined ... -
Globally Injective Geometry Optimization with Non-Injective Steps
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We present a method to minimize distortion and compute globally injective mappings from non-injective initialization. Many approaches for distortion minimization subject to injectivity constraints require an injective ... -
Gauss Stylization: Interactive Artistic Mesh Modeling based on Preferred Surface Normals
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Extending the ARAP energy with a term that depends on the face normal, energy minimization becomes an effective stylization tool for shapes represented as meshes. Our approach generalizes the possibilities of Cubic ... -
Progressive Discrete Domains for Implicit Surface Reconstruction
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Many global implicit surface reconstruction algorithms formulate the problem as a volumetric energy minimization, trading data fitting for geometric regularization. As a result, the output surfaces may be located arbitrarily ...
