    • Normal orientation methods for 3D offset curves, sweep surfaces and skinning 

      Siltanen, Pekka; Woodward, Charles (Blackwell Science Ltd and the Eurographics Association, 1992)
      Computing an offset curve to a 3D curve involves the basic problem of normal orientation in space. The same thing is encountered when interpolating surfaces with 3D sweep or skinning methods. Different methods for normal ...
    • A NORMAL-BUFFER VECTORIZED SURFACE SHADING MODEL 

      Curington, Ian J. (The Eurographics Association, 1985)
      A surface rendering implementation is described that separates visibility operations from surface shading operations with a Normal-Buffer data structure. This allows for scene complexity independent shading operations at ...

      Liu, Hsueh-Ti Derek; Jacobson, Alec (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      This paper introduces a new method to stylize 3D geometry. The key observation is that the surface normal is an effective instrument to capture different geometric styles. Centered around this observation, we cast stylization ...

      Arnold, D. B.; Day, A. M. (Eurographics Association, 1999)
      This paper describes the early work on implementing a visitor attraction based on the heritage of the Norwich area. The project has been in planning for about three years, but has only just been funded and is due to open ...
    • Not All Areas Are Equal: A Novel Separation-Restoration-Fusion Network for Image Raindrop Removal 

      Ren, Dongdong; Li, Jinbao; Han, Meng; Shu, Minglei (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Detecting and removing raindrops from an image while keeping the high quality of image details has attracted tremendous studies, but remains a challenging task due to the inhomogeneity of the degraded region and the ...
    • A Note on 3D-Clip Optimisation 

      Hubl, Josef (Blackwell Science Ltd and the Eurographics Association, 1993)
      In order to optimize the transformation-clipping-pipeline of PHIGS or GKS-3D it is sometimes necessary to determine whether a plane intersects a perpendicular volume or not. The solution to this problem is not very ...
    • A Note on Random Thresholding for Colour Synthesis 

      Lastra, G.L.; Rudinger, E.N. (Blackwell Publishing Ltd and the Eurographics Association, 1988)
      A simple algorithm that improves colour shaded images is presented. The algorithm does not trade spatial resolution for intensity resolution. The basic technique, based on random thresholding modulated by a pseudo-random ...
    • Notes on the Mathematics of the PHIGS Viewing Pipeline 

      Krammer, Gergely (Blackwell Publishing Ltd and the Eurographics Association, 1989)
      It is well known that homogeneous linear matrix transformations of the projective space may be efficiently used for the representation and the execution of common geometrical transformations but the general class of such ...
    • NOVA: Rendering Virtual Worlds with Humans for Computer Vision Tasks 

      Kerim, Abdulrahman; Aslan, Cem; Celikcan, Ufuk; Erdem, Erkut; Erdem, Aykut (© 2021 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2021)
      Today, the cutting edge of computer vision research greatly depends on the availability of large datasets, which are critical for effectively training and testing new methods. Manually annotating visual data, however, is ...
    • Novative Rendering and Physics Engines to Apprehend Special Relativity 

      Doat, Tony; Parizot, Etienne; Vézien, Jean-Marc (The Eurographics Association, 2011)
      Relativity, as introduced by Einstein, is regarded as one of the most important revolutions in the history of physics. Nevertheless, the observation of direct outcomes of this theory on mundane objects is impossible because ...
    • Novel Application of 3D Documentation Techniques at a Submerged Late Pleistocene Cave Site in Quintana Roo, Mexico 

      Rissolo, Dominique; Blank, Alberto Nava; Petrovic, Vid; Arce, Roberto Chavez; Jaskolski, Corey; Erreguerena, Pilar Luna; Chatters, James C. (IEEE, 2015)
      The submerged cave site of Hoyo Negro, located along the east coast of the Yucatan Peninsula, contains a diverse fossil assemblage of extinct megafauna as well as a nearly complete human skeleton. The remote nature of the ...
    • A Novel Approach for Cooperative Motion Capture (COMOCAP) 

      Welch, Gregory; Wang, Tianren; Bishop, Gary; Bruder, Gerd (The Eurographics Association, 2018)
      Conventional motion capture (MOCAP) systems, e.g., optical systems, typically perform well for one person, but less so for multiple people in close proximity. Measurement quality can decline with distance, and even drop ...
    • A Novel Approach for Delaunay 3D Reconstruction with a Comparative Analysis in the Light of Applications
