Learning Line Features in 3D Geometry
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Feature detection in geometric datasets is a fundamental tool for solving shape matching problems such as partial symmetry detection. Traditional techniques usually employ a priori models such as crease lines that are ...
Optimal Spline Approximation via l0-Minimization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Splines are part of the standard toolbox for the approximation of functions and curves in Rd. Still, the problem of finding the spline that best approximates an input function or curve is ill-posed, since in general this ...
Intrinsic Shape Matching by Planned Landmark Sampling
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Recently, the problem of intrinsic shape matching has received a lot of attention. A number of algorithms have been proposed, among which random-sampling-based techniques have been particularly successful due to their ...
Visualization of Regular Polytopes in Three and Four Dimensions
(Blackwell Science Ltd and the Eurographics Association, 1994)
Nontrivial regular polytopes only exist in three and four dimensions. This paper describes a software package that allows to interactively visualize and analyze these regular polytopes. The following four tools are available: ...
Material Editing in Complex Scenes by Surface Light Field Manipulation and Reflectance Optimization
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
This work addresses the challenge of intuitive appearance editing in scenes with complex geometric layout and complex, spatially-varying indirect lighting. In contrast to previous work, that aimed to edit surface reflectance, ...
Anisotropic Radiance-Cache Splatting for Efficiently Computing High-Quality Global Illumination with Lightcuts
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Computing global illumination in complex scenes is even with todays computational power a demanding task. In this work we propose a novel irradiance caching scheme that combines the advantages of two state-of-the-art ...
Goniometric Diagram Mapping for Hemisphere
(Eurographics Association, 2003)
Describing the light intensity over the hemisphere using a goniometric diagram is a common practice in the lighting industry and is prescribed for instance by IESNA (Illuminating Engineering Society of North America) ...
Interactive Motion Mapping for Real-time Character Control
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Abstract It is now possible to capture the 3D motion of the human body on consumer hardware and to puppet in real time skeleton-based virtual characters. However, many characters do not have humanoid skeletons. Characters ...
Mutable Elastic Models for Sculpting Structured Shapes
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
In this paper, we propose a new paradigm for free-form shape deformation. Standard deformable models minimize an energy measuring the distance to a single target shape. We propose a new, ''mutable'' elastic model. It ...
Perceptually-motivated Real-time Temporal Upsampling of 3D Content for High-refresh-rate Displays
(The Eurographics Association and Blackwell Publishing Ltd, 2010)
High-refresh-rate displays (e. g., 120 Hz) have recently become available on the consumer market and quickly gain on popularity. One of their aims is to reduce the perceived blur created by moving objects that are tracked ...
