    • A Reference Model for the Visualisation of Multi-Dimensional Data 

      Bergeron, R. Daniel; Grinstein, Georges G. (Eurographics Association, 1989)
      This paper presents a reference model for the development of systems for the visualization of multidimensional data. The purpose of the reference model is to build a conceptual basis for thinking about multi-dimensional ...

      In this paper we discuss two kinds of constraint satisfaction problems that arise in the context of geometric modelling, In particular in the modification of 2-D wire-frame diagrams that are subject to an arbitrary number ...

    • Reference‐based Screentone Transfer via Pattern Correspondence and Regularization 

      Li, Zhansheng; Zhao, Nanxuan; Wu, Zongwei; Dai, Yihua; Wang, Junle; Jing, Yanqing; He, Shengfeng (© 2023 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd., 2023)
      Adding screentone to initial line drawings is a crucial step for manga generation, but is a tedious and human‐laborious task. In this work, we propose a novel data‐driven method aiming to transfer the screentone pattern ...

    • Refinable Multi-sided Caps for Bi-quadratic Splines 

      Karciauskas, Kestutis; Peters, Jörg (The Eurographics Association, 2021)
      Subdivision surfaces based on bi-quadratic splines have a control net, the DS-net, whose irregularities are n-sided facets. To date their limit shape is poor due to a small footprint of the refinement rules and the difficulty ...

    • Refinement Criteria Based on f-Divergences 

      Rigau, Jaume; Feixas, Miquel; Sbert, Mateu (The Eurographics Association, 2003)
      In several domains a refinement criterion is often needed to decide whether to go on or to stop sampling a signal. When the sampled values are homogeneous enough, we assume that they represent the signal fairly well and ...

    • Refinement criteria for adaptive stochastic ray tracing of textures 

      van Walsum, Theo; van Nieuwenhuizen, Peter R.; Jansen, Frederik W. (Eurographics Association, 1991)
      Adaptive stochastic ray tracing is a rendering technique that generates high-quality anti-aliased images by sampling the image in a non-regular pattern that is adaptively refined. Image refinement can be guided by image ...

    • Refinement of Hair Geometry by Strand Integration 

      Maeda, Ryota; Takayama, Kenshi; Taketomi, Takafumi (The Eurographics Association and John Wiley & Sons Ltd., 2023)
      Reconstructing 3D hair is challenging due to its complex micro-scale geometry, and is of essential importance for the efficient creation of high-fidelity virtual humans. Existing hair capture methods based on multi-view ...

    • Refinement of the Stress Contour Plots by the Local Interpolations, Extrapolations ans Averaging 

      Draskovic, Z.; Berkovic, M. (The Eurographics Association, 1983)
      The purpose of this paper is an attempt to improve the stress contour plots for the simplest two-dimensional finite elements. The proposed approach is achieved by the use of the simple local interpolations, extrapolations ...

    • Refinery: Visual Exploration of Large, Heterogeneous Networks through Associative Browsing 

      Kairam, Sanjay; Henry-Riche, Nathalie; Drucker, Steven; Fernandez, Roland; Heer, Jeffrey (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Browsing is a fundamental aspect of exploratory information-seeking. Associative browsing represents a common and intuitive set of exploratory strategies in which users step iteratively from familiar to novel bits of ...

    • Reflectance and Shape Estimation for Cartoon Shaded Objects 

      Todo, Hideki; Yamaguchi, Yasushi (The Eurographics Association, 2016)
      Although many photorealistic relighting methods provide a way to change the illumination of objects in a digital photograph, it is currently difficult to relight a cartoon shading style in digital illustrations. The main ...

    • Reflectance Models with Fast Importance Sampling 

      Neumann, Laszlo; Neumann, Attila; Szirmay-Kalos, Laszlo (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      We introduce a physically plausible mathematical model for a large class of BRDFs. The new model is as simple as the well-known Phong model, but eliminates its disadvantages. It gives a good visual approximation for many ...

    • Reflectance Sharing: Image-based Rendering from a Sparse Set of Images 

      Zickler, Todd; Enrique, Sebastian; Ramamoorthi, Ravi; Belhumeur, Peter (The Eurographics Association, 2005)
      When the shape of an object is known, its appearance is determined by the spatially-varying reflectance function defined on its surface. Image-based rendering methods that use geometry seek to estimate this function from ...

    • Reflected and Transmitted Irradiance from Area Sources using Vertex Tracing 

      Stark, Michael M.; Riesenfeld, Richard F. (The Eurographics Association, 2001)
      Computing irradiance analytically from polygonal luminaires in polygonal environments has proven effective for direct lighting applications in diffuse radiosity environments. Methods for analytic integration have traditionally ...

    • Reflected Infrared Imaging: Revisiting the Fundamentals 

      Webb, E. Keats (IEEE, 2015)
      Reflected infrared imaging has been used as an investigation tool for paintings and paper conservation since the 1930s. The technique can reveal underdrawings, expose compositional changes, provide information about ...

    • Reflected-Scene Impostors for Realistic Reflections at Interactive Rates 

      Popescu, Voicu; Mei, Chunhui; Dauble, Jordan; Sacks, Elisha (The Eurographics Association and Blackwell Publishing, Inc, 2006)
