    • Deformations of Sweep Objects in Solid Modelling 

      Post, Frits H.; Klok, Fopke (The Eurographics Association, 1986)
      Deformations, such as bending, twisting and tapering, are important operations for modifying the shape of solid objects. In this paper, we present methods to deform objects defined by sweeping. A closed 2D polygon (the ...

      A discretely sampled object representation (DSOR) defines a graphical model using data obtained by a sampling process, which takes a collection of samples at discrete positions in space in order to capture certain geometrical ...

    • Delaunay Mesh Construction 

      Dyer, Ramsay; Zhang, Hao; Moeller, Torsten (The Eurographics Association, 2007)
      We present algorithms to produce Delaunay meshes from arbitrary triangle meshes by edge flipping and geometrypreserving refinement and prove their correctness. In particular we show that edge flipping serves to reduce mesh ...

    • Delaunay Meshing and Repairing of NURBS Models 

      Xiao, Xiao; Alliez, Pierre; Busé, Laurent; Rineau, Laurent (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      CAD models represented by NURBS surface patches are often hampered with defects due to inaccurate representations of trimming curves. Such defects make these models unsuitable to the direct generation of valid volume meshes, ...

    • Delaunay Painting: Perceptual Image Colouring from Raster Contours with Gaps 

      Parakkat, Amal Dev; Memari, Pooran; Cani, Marie‐Paule (© 2022 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd., 2022)
      We introduce Delaunay Painting, a novel and easy‐to‐use method to flat‐colour contour‐sketches with gaps. Starting from a Delaunay triangulation of the input contours, triangles are iteratively filled with the appropriate ...

    • A Delaunay-Based Method for Surface Approximation 

      Floriani, L.De; Falcidieno, B.; C.Pienovi, (The Eurographics Association, 1983)
      This paper describes a method for constructing a surface representation model from a given set of data points.A Triangulated Irregular. Network has been chosen as data structure, thus representing the surface as a set of ...

    • Delauney Triangulations and the Radiosity Approach 

      Schuierer, Sven (Eurographics Association, 1989)
      The radiosity approach requires the subdivision of complex surfaces into simple components called patches. Since we assume to have constant intensity over a patch, the generation of regular patches is a desirable property ...

    • Delivering Effective and Usable Interactive 3D Visualization on Lightweight Mobile Devices 

      Holmes, I. R.; Kalawsky, R. S. (The Eurographics Association, 2007)
      3D visualization has significantly enhanced scientists ability to discover important new insights into their data. In this paper we focus specifically on associated HCI and human factors of remote 3D visualization. We ...

    • Delivering Interactivity to Complex Tone Mapping Operators 

      Artusi, Alessandro; Bittner, Jirí; Wimmer, Michael; Wilkie, Alexander (The Eurographics Association, 2003)
      The accurate display of high dynamic range images requires the application of complex tone mapping operators. These operators are computationally costly, which prevents their usage in interactive applications. We propose ...

    • The Delta Radiance Field 

      Franke, Tobias Alexander (2015-09-11)
      The wide availability of mobile devices capable of computing high fidelity graphics in real-time has sparked a renewed interest in the development and research of Augmented Reality applications. Within the large spectrum ...

    • Demand-Driven Geometry Transmission for Distributed Virtual Environments 

      Schmalstieg, Dieter; Gervautz, Michael (Blackwell Science Ltd and the Eurographics Association, 1996)
      We present a strategy for rendering in distributed virtual environments. A geometry database is maintained by a server, while users invoke individual clients to interact with the environment. Instead of downloading a ...

    • Demo of an Olfactory Game Using Paired Odors to Increase the Odor Range, Enabling Immersive Olfactory Experience in VR Environments 

      Onai, Saya; Cohen, Nathan; Nakamoto, Takamichi (The Eurographics Association, 2022)
      Olfaction is a key human sense, but olfactory human interface technologies are not yet so common compared to visual and auditory devices. Recently, the utilization of olfactory stimuli in digital contexts has been attracting ...
