    • I3T: Using Interactive Computer Graphics to Teach Geometric Transformations 

      Felkel, Petr; Magana, Alejandra J.; Folta, Michal; Sears, Alexa Gabrielle; Benes, Bedrich (The Eurographics Association, 2018)
      Geometric transformations play an important role in a vast variety of disciplines. Although they belong to the fundamental concepts, they are also difficult to comprehend. Thousands of students take courses of algebra every ...

    • Identification of Dynamic Mass Spring Parameters for Deformable Body Simulation 

      Lloyd, Bryn; Kirac, S.; Szekely, Gabor; Harders, Matthias (The Eurographics Association, 2008)
      Mass spring systems (MSS) are frequently used to simulate deformable objects because of their conceptual sim- plicity and computational speed. Unfortunately, the model parameters (spring coefficients, masses) are not related ...

    • IISPH-FLIP for Incompressible Fluids 

      Cornelis, Jens; Ihmsen, Markus; Peer, Andreas; Teschner, Matthias (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We propose to use Implicit Incompressible Smoothed Particle Hydrodynamics (IISPH) for pressure projection and boundary handling in Fluid-Implicit-Particle (FLIP) solvers for the simulation of incompressible fluids. This ...

    • An illumination model for ray-tracing 

      MONTCEL, Bruno TEZENAS DU; NICOLAS, Alain (The Eurographics Association, 1985)

      We present a novel algorithm, IlluminationCut, for rendering images using the many-lights framework. It handles any light source that can be approximated with virtual point lights (VPLs) as well as highly glossy materials. ...

    • Illustrative Flow Visualization: State of the Art, Trends and Challenges 

      Brambilla, Andrea; Carnecky, Robert; Peikert, Ronald; Viola, Ivan; Hauser, Helwig (The Eurographics Association, 2012)
      Flow visualization is a well established branch of scientific visualization and it currently represents an invaluable resource to many fields, like automotive design, meteorology and medical imaging. Thanks to the capabilities ...

    • Illustrative Visualization 

      Viola, Ivan; Gröller, Meister E.; Hadwiger, Markus; Bühler, Katja; Preim, Bernhard; Ebert, David (The Eurographics Association, 2005)
      The tutorial presents state-of-the-art visualization techniques inspired by traditional technical and medical illustrations. Such techniques exploit the perception of the human visual system and provide effective visual ...

    • Illustrative Visualization for Medicine and Science 

      Viola, I.; Sousa, M. C.; Ebert, D.; Andrews, B.; Gooch, B.; Tietjen, C. (The Eurographics Association, 2006)
      This tutorial presents recent and important research and developments from academia in illustrative, nonphotorealistic rendering (NPR) focusing on its use for medical/science subjects. Lectures are organized within a ...

    • Image and Video Abstraction by Coherence-Enhancing Filtering 

      Kyprianidis, Jan Eric; Kang, Henry (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      In this work, we present a non-photorealistic rendering technique to create stylized abstractions from color images and videos. Our approach is based on adaptive line integral convolution in combination with directional ...

    • Image Appearance Exploration by Model-Based Navigation 

      Shapira, L.; Shamir, A.; Cohen-Or, D. (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Changing the appearance of an image can be a complex and non-intuitive task. Many times the target image colors and look are only known vaguely and many trials are needed to reach the desired results. Moreover, the effect ...

    • An Image based Measurement System for Anisotropic Reflection 

      Karner, Konrad F.; Mayer, Heinz; Gervautz, Michael (Blackwell Science Ltd and the Eurographics Association, 1996)
      This paper introduces an image based method for measuring bidirectional reflectance distribution functions (BRDF). The measurement system uses a CCD camera connected to a workstation to capture images from the material ...

    • Image Editing with Intelligent Paint 

      Reese, Jack; Barrett, William (Eurographics Association, 2002)
      Intelligent Paint provides a new tool for interactively selecting image objects or regions of interest, while simultaneously applying filters or effects directly to the selection(s). By coupling adaptive cost-ordered region ...

    • IMAGE MODELING ASPECTS OF NON-PROCEDURAL PARALLEL PROCESSING LANGUAGE
