    • Geometric Simplification of Foliage 

      Remolar, Inmaculada; Chover, Miguel; Belmonte, Oscar; Ribelles, Jose; Rebollo, Cristina (Eurographics Association, 2002)
      One of the most important challenges in real-time rendering of outdoor scenes is the representation of vegetation. This is due to the vast amount of polygons that are used to model vegetable species. The present automatic ...
    • Global Illumination for Interactive Applications and High-Quality Animations 

      Damez, Cyrille; Dmitriev, Kirill; Myszkowski, Karol (Eurographics Association, 2002)
      One of the main obstacles to the use of global illumination in image synthesis industry is the considerable amount of time needed to compute the lighting for a single image. Until now, this computational cost has prevented ...
    • Hardware-Assisted Relief Texture Mapping 

      Fujita, Masahiro; Kanai, Takashi (Eurographics Association, 2002)
      Image-Based Rendering by Warping (IBRW) creates three-dimensional scene by deforming several 2D images with depth information. Image-based rendering has an advantage compared to traditional polygon rendering that the ...
    • 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 ...
    • An Image-Based Radiosity Representation 

      Mertens, Tom; Van Reeth, Frank (Eurographics Association, 2002)
      We present a geometry-independent radiosity representation which stems from image-based methodologies. Our image-based representation is inspired by the concept of layered depth images. To construct the radiosity function ...
    • Improved Bump Mapping by using Quadratic Vector Interpolation 

      Hast, Hans Anders; Barrera, Tony; Bengtsson, Ewert (Eurographics Association, 2002)
      Bump mapping is a technique that perturbs normals used in the illumination computation in order to make the surface appear rough or wrinkled. Standard graphics hardware linearly interpolates rotated vectors in the direction ...
    • Improved Integration for Cloth Simulation 

      Parks, David L.; Forsyth, David A. (Eurographics Association, 2002)
      Most methods of cloth simulation produce animations that do not move very freely; the result often looks like the material is “swimming”. The primary sources of this phenomenon are the non-physical dissipation terms often ...
    • Information-Theoretic Oracle Based on Kernel Smoothness for Hierarchical Radiosity 

      Feixas, Miquel; Rigau, Jaume; Bekaert, Philippe; Sbert, Mateu (Eurographics Association, 2002)
      One of the main problems in the radiosity method is how to discretise the surfaces of a scene into mesh elements that allow us to accurately represent illumination. In this paper we present a robust information-theoretic ...
    • Interactive High-Quality Volume Rendering with Flexible Consumer Graphics Hardware 

      Engel, Klaus; Ertl, Thomas (Eurographics Association, 2002)
      Recently, the classic rendering pipeline in 3D graphics hardware has become flexible by means of programmable geometry engines and rasterization units. This development is primarily driven by the mass market of computer ...
    • 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 ...
