    • G2 Tensor Product Splines over Extraordinary Vertices 

      Loop, Charles; Schaefer, Scott (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a second order smooth filling of an n-valent Catmull-Clark spline ring with n biseptic patches. While an underdetermined biseptic solution to this problem has appeared previously, we make several advances in ...
    • GA based Adaptive Sampling for Image-based Walkthrough 

      Lee, Dong Hoon; Kim, Jong Ryul; Jung, Soon Ki (The Eurographics Association, 2006)
      This paper presents an adaptive sampling method for image-based walkthrough. Our goal is to select minimal sets from the initially dense sampled data set, while guaranteeing a visual correct view from any position in any ...
    • Galilean Invariant Extraction and Iconic Representation of Vortex Core Lines 

      Sahner, Jan; Weinkauf, Tino; Hege, Hans-Christian (The Eurographics Association, 2005)
      While vortex region quantities are Galilean invariant, most methods for extracting vortex cores depend on the frame of reference. We present an approach to extracting vortex core lines independently of the frame of reference ...
    • A Game Engine-based Multi-Projection Virtual Environment with System-Level Synchronization 

      Hashimoto, Naoki; Ishida, Yoshihiko; Sato, Makoto (The Eurographics Association, 2005)
      In multi-projector displays, which surround users with high-resolution images, a PC-Cluster is often used for realistic and real-time image generation. However, developing applications that support parallel processing on ...
    • Games For Sketch Data Collection 

      Johnson, Gabe; Do, Ellen Yi-Luen (The Eurographics Association, 2009)
      This article describes sketching games made for the purpose of collecting data about how people make and describe hand-made drawings. The approach leverages human computation, whereby players provide information about ...
    • Gamut Mapping Spatially Varying Reflectance with an Improved BRDF Similarity Metric 

      Pereira, Thiago; Rusinkiewicz, Szymon (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Recent spatially varying reflectance (svBRDF) printing systems can reproduce an input document as a combination of matte, glossy and metallic inks. Due to the limited number of inks, this reproduction process incurs some ...
    • gamutHeatMap: Visualizing the Colour Shift of Rendering Intent Transformations 

      Gat, Christopher; Zhang, Hanyu; German, Daniel M.; Tory, Melanie (The Eurographics Association, 2011)
      When a photograph is printed, its original colours are converted to those of the output medium using a rendering intent transformation. This process takes into consideration the colour properties of the paper and the printer ...
    • Gathering for Free in RandomWalk Radiosity 

      Sbert, Mateu; Brusi, Alex; Bekaert, Philippe (The Eurographics Association, 1999)
      We present a simple technique that improves the efficiency of random walk algorithms for radiosity. Each generated random walk is used to simultaneously sample two distinct radiosity estimators. The first estimator is the ...
    • Gaze Analysis of BRDF Distortions 

      Filip, J.; Havran, V.; Myszkowski, K. (The Eurographics Association, 2016)
      BRDFs are currently used as a standard representation of material surface reflectance properties either in the from of tabulated measurements or a parametric model. However, the compression of tabulated representations as ...
    • Gaze Driven Animation of Eyes 

      Neog, Debanga Raj; Ranjan, Anurag; Cardoso, João L.; Pai, Dinesh K. (ACM Siggraph, 2015)
      We present a data driven model of eye movement, that includes movement of the globes, the periorbital soft tissues and eyelids and also the formation of wrinkles in the tissues. We describe a pipeline for measurement and ...
    • A Gaze-enabled Graph Visualization to Improve Graph Reading Tasks 

      Okoe, Mershack; Alam, Sayeed Safayet; Jianu, Radu (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Performing typical network tasks such as node scanning and path tracing can be difficult in large and dense graphs. To alleviate this problem we use eye-tracking as an interactive input to detect tasks that users intend ...
    • GCH 2016: Frontmatter 

      Chiara Eva Catalano; Livio De Luca (Eurographics Association, 2016)
    • GCH 2019: Frontmatter 

      Rizvic, Selma; Rodriguez Echavarria, Karina (Eurographics Association, 2019)
    • Gearbox Widget for Fine Adjustments by Hand Motion 

      OSAWA, Noritaka; REN, Xiangshi (The Eurographics Association, 2003)
      manipulation by hand is not suitable for making fine adjustments to virtual objects in an immersive environment because it is difficult to hold an unsupported hand in midair and then to release an object at a fixed point. ...
    • GEMSe: Visualization-Guided Exploration of Multi-channel Segmentation Algorithms 

      Fröhler, Bernhard; Möller, Torsten; Heinzl, Christoph (The Eurographics Association and John Wiley & Sons Ltd., 2016)
