    • Interactive Polygonisation for Function-based Modelling 

      Sourin, Alexei; Levinski, Konstantin (Eurographics Association, 2002)
      This paper addresses interactive function-based shape modelling. Interactive modification of the function model with concurrent visualization of the respective polygonal mesh lets us provide both the interactivity and any ...
    • Interactive Visualization with Programmable Graphics Hardware 

      Ertl, Thomas (Eurographics Association, 2002)
      One of the main scientific goals of visualization is the development of algorithms and appropriate data models which facilitate interactive visual analysis and direct manipulation of the increasingly large data sets which ...
    • Interpolating 2D Shape Hierarchically 

      Johan, Henry; Nishita, Tomoyuki (Eurographics Association, 2002)
      Shape interpolation has been widely used in the field of computer graphics for modeling and for creating visual effects. This paper presents a novel hierarchical method to interpolate between two 2D shapes. A hierarchical ...
    • Knowledge-Based Representation of Cinematic Expression and its Application to Animation 

      Friedman, Doron; Feldman, Yishai (Eurographics Association, 2002)
      Camera control in virtual environments received growing attention recently, and some of the research turned to cinematography as a source for inspiration. Cinematic knowledge is a highly challenging domain for formalization. ...
    • Measuring and Rendering Art Paintings Using an RGB Camera 

      Tominaga, Shoji; Tanaka, Norihiro (Eurographics Association, 2002)
      A method is proposed for measuring and rendering of art paints by using the simple system of an RGB camera only. The surface shape of an art painting is considered as a rough plane rather than a three-dimensional curved ...
    • Mesh Decimation for Displacement Mapping 

      Collins, Gordon; Hilton, Adrian (Eurographics Association, 2002)
      We present a mesh decimation algorithm for triangular meshes. Unlike other decimation algorithms we are not concerned with geometric error but with the existence of a displacement mapping which can map between the original ...
    • A Method for Creating Mosaic Images Using Voronoi Diagrams 

      Dobashi, Yoshinori; Haga, Toshiyuki; Johan, Henry; Nishita, Tomoyuki (Eurographics Association, 2002)
      This paper proposes a non-photorealistic rendering method that creates an artistic effect called mosaicing. The proposed method converts images provided by the user into the mosaic images. Commercial image editing applications ...
    • Modeling and Rendering of Synthetic Plants 

      Deussen, Oliver (Eurographics Association, 2002)
      Plant geometries: → important for many indoor and outdoor scenes → hard to generate and to manipulate → tricky to convert → today: seldomly used → tomorrow: standard of most animation systems
    • Modeling Visual Attention in VR: Measuring the Accuracy of Predicted Scanpaths 

      Duchowski, Andrew; Marmitt, Gerd (Eurographics Association, 2002)
      Dynamic human vision is an important contributing factor to the design of perceptually-based Virtual Reality. A common strategy relies on either an implicit assumption or explicit measurement of gaze direction. Given the ...
    • More than RGB: Spectral Trends in Color Reproduction 

      Bell, Ian E.; Baranoski, Gladimir V. G. (Eurographics Association, 2002)
      Early rendering algorithms relied exclusively on three-dimensional spaces for color computation, such as RGB and CIE XYZ. Recent rendering advances use full spectral information for illuminants and surfaces, resulting in ...
    • Multi-dimensional and Multi-scale Visualizer of Large XML Documents 

      Jacquemin, Christian; Jardino, Michele (Eurographics Association, 2002)
      3D-XV (3-Dimensional XML Visualizer) is an interactive graphical interface for accessing large structured documents. It relies on a geometrical model that combines a sequential organization and a hierarchical structure. ...
    • Normal Enhancement for Interactive Non-photorealistic Rendering 

      Cignoni, Paolo; Scopigno, Roberto; Tarini, Marco (Eurographics Association, 2002)
      We present a simple technique to improve the perception of shape of an object. Bump mapping is well-known in the computer graphics community for providing the impression of small-scale geometrical features (which actually ...
    • On the Integration of Synthetic Objects with Real-World Scenes 

      Abad, Francisco; Camahort, Emilio; Vivó, Roberto (Eurographics Association, 2002)
      This paper presents a method for integrating synthetic objects in real-world photographs. We take a set of photographs of a real scene and build a simple image-based model. We use high dynamic range images to build an ...
    • Point Based Computer Graphics 

      Gross, Markus; Pfister, Hanspeter; Zwicker, Matthias; Pauly, Mark; Stamminger, Marc; Alexa, Marc (Eurographics Association, 2002)
    • Programmable Graphics Hardware for Interactive Visualization 

      Ertl, Thomas; Weiskopf, Daniel; Kraus, Martin; Engel, Klaus; Weiler, Manfred; Hopf, Matthias; Röttger, Stefan; Rezk-Salama, Christof (Eurographics Association, 2002)
    • Real-time 3D Deformations by Means of Compactly Supported Radial Basis Functions 

      Kojekine, Nikita; Savchenko, Vladimir; Senin, Mikhail; Hagiwara, Ichiro (Eurographics Association, 2002)
      We present an approach to real-time animation of deformable objects. Optimization of algorithms using compactly supported radial basis functions (CSRBF) allows us to generate deformations performed fast enough for such ...
    • Real-Time Animated Grass 

      Bakay, Brook; Lalonde, Paul; Heidrich, Wolfgang (Eurographics Association, 2002)
      We present a simple method to render fields of grass, animated in the wind, in real-time. The technique employs vertex shaders to render displacement maps with Russian-doll style transparent shells. Animation is achieved ...
    • Rendering Artistic Line Drawings Using Off-the-Shelf 3-D Software 

      Loviscach, Jörn (Eurographics Association, 2002)
      Most commercial 3-D software packages used for animated films and still picture production offer merely rudimentary support for non-photorealistic rendering. However, nearly all of these packages possess interfaces which ...
