    • A Concept for Reconstructing Stucco Statues from historic Sketches using synthetic Data only 

      Pöllabauer, Thomas; Kühn, Julius (The Eurographics Association, 2022)
      In medieval times, stuccoworkers used a red color, called sinopia, to first create a sketch of the to-be-made statue on the wall. Today, many of these statues are destroyed, but using the original drawings, deriving from ...

    • Concept of Skeleton Texture Mapping 

      Madaras, Martin (The Eurographics Association, 2011)
      This article introduces an idea for novel way of mapping textures onto a surface of 3D model. Our technique is based on two interlocking mappings, the first one maps surface vertices onto computed skeleton and the second ...

    • ConceptGraph: A Formal Model for Interpretation and Reasoning During Visual Analysis 

      Karer, B.; Scheler, I.; Hagen, H.; Leitte, H. (© 2020 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2020)
      In order to discuss the kinds of reasoning a visualization supports and the conclusions that can be drawn within the analysis context, a theoretical framework is needed that enables a formal treatment of the reasoning ...

      von Tycowicz, Christoph (von Tycowicz, 2014-05-05)
      We propose new model reduction techniques for the construction of reducedshape spaces of deformable objects and for the approximation ofreduced internal forces that accelerate the construction of a reduced dynamicalsystem, ...

    • Concepts and methods to support the development and evaluation of remote collaboration using augmented reality 

      Marques, Bernardo (University of Aveiro, 2021)
      Remote Collaboration using Augmented Reality (AR) shows great potential to establish a common ground in physically distributed scenarios where team-members need to achieve a shared goal. However, most research efforts in ...

    • Conceptualizing Birkhoff's Aesthetic Measure Using Shannon Entropy and Kolmogorov Complexity 

      Rigau, Jaume; Feixas, Miquel; Sbert, Mateu (The Eurographics Association, 2007)
      In 1928, George D. Birkhoff introduced the Aesthetic Measure, defined as the ratio between order and complexity, and, in 1965, Max Bense analyzed Birkhoff s measure from an information theory point of view. In this paper, ...

    • Conceptualizing Visual Uncertainty in Parallel Coordinates 

      Dasgupta, Aritra; Chen, Min; Kosara, Robert (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Uncertainty is an intrinsic part of any visual representation in visualization, no matter how precise the input data. Existing research on uncertainty in visualization mainly focuses on depicting data-space uncertainty in ...

    • Conceptualizing, Managing and Developing: A Web Based 3D City Information Model for Urban Energy Demand Simulation 

      Padsala, Rushikesh; Coors, Volker (The Eurographics Association, 2015)
      In this paper we describe a concept to manage and develop a web based virtual 3D scene, based on CityGML LoD 2 models, DTM tiles, ortho-photos and energy simulation results of specific heating demand and photovoltaic ...

    • Concepture: A Regular Language Based Framework for Recognizing Gestures with Varying and Repetitive Patterns 

      Donmez, Nilgun; Singh, Karan (The Eurographics Association, 2012)
      We present Concepture, a framework based on regular language grammars for the authoring and recognition of sketched gestures with infinitely varying and repetitive patterns. Such gestures, while often seen in gesture based ...

    • Concerning the Specification of User Interfaces 

      Duce, D. A. (Blackwell Publishing Ltd and the Eurographics Association, 1985)

    • A Concise and Provably Informative Multi-Scale Signature Based on Heat Diffusion 

      Sun, Jian; Ovsjanikov, Maks; Guibas, Leonidas (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We propose a novel point signature based on the properties of the heat diffusion process on a shape. Our signature, called the Heat Kernel Signature (or HKS), is obtained by restricting the well-known heat kernel to the ...

    • A concise b-rep data structure for stratified subanalytic objects 

      Gomes, Abel J.P. (The Eurographics Association, 2003)
      Current geometric kernels suffer from poor abstraction and design of their data structures. In part, this is due to the lack of a general mathematical framework for geometric modelling and processing. As a result, there ...

    • Concise Tour to the Virtual Old Prague 

      Zara, Jiri (Eurographics Association, 2002)
      This paper describes a structure and a user interface of the Internet based 3D presentation of existing historical part of city Prague. The application offers a smooth tour to selected regions of the real city, utilizing ...

    • Concurrent Binary Trees (with application to longest edge bisection) 

      Dupuy, Jonathan (ACM, 2020)
      We introduce the concurrent binary tree (CBT), a novel concurrent representation to build and update arbitrary binary trees in parallel. Fundamentally, our representation consists of a binary heap, i.e., a 1D array, that ...
