    • Frame-Coherent Stippling 

      Meruvia Pastor, Oscar E.; Strothotte, Thomas (Eurographics Association, 2002)
      Stippling is an artistic rendering technique where shading and texture is given by placing points or stipples on the canvas until the desired darkness is achieved. Computer-generated stippling has focused on producing high ...

    • Visibility Preprocessing Using Spherical Sampling of Polygonal Patches 

      Meruvia Pastor, Oscar E. (Eurographics Association, 2002)
      A technique is presented that permits fast view-reconstruction of individual objects. This method improves a previous approach to solve the problem of approximated view reconstruction by combining clustering of polygons ...

    • 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 ...

    • Simulation of Cumuliform Clouds Based on Computational Fluid Dynamics 

      Miyazaki, Ryo; Dobashi, Yoshinori; Nishita, Tomoyuki (Eurographics Association, 2002)
      Simulation of natural phenomena is one of the important research fields in computer graphics. In particular, clouds play an important role in creating images of outdoor scenes. Fluid simulation is effective in creating ...

    • 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 ...

    • Extraction of Critical Points and Nets Based on Discrete Gradient Vector Field 

      De Floriani, Leila; Mesmoudi, Mohammed Mostefa; Danovaro, Emanuele (Eurographics Association, 2002)
      In this paper we address the problem of representing the topology of discrete scalar fields defined on triangulated domains. To this aim, we use the notion of discrete gradient vector field that we have introduced in [4] ...

    • 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 ...

    • Adaptive Compression of Human Animation Data 

      Ahmed, Amr Adel Hassan; Hilton, Adrian; Mokhtarian, Farzin (Eurographics Association, 2002)
      In this paper we introduce an adaptive motion compression technique using the discrete wavelet transform. Based on the analysis of human animation data, and its frequency contents, the wavelet analysis is utilised to achieve ...

    • 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 ...

    • Dependent Tests Driven Filtering in Monte-Carlo Global Illumination 

      Csonka, Ferenc; Szirmay-Kalos, Laszlo; Kelemen, Csaba; Antal, György (Eurographics Association, 2002)
      This paper presents a multi-phase algorithm to solve the global illumination problem. In the first phase dependent tests are applied, i.e. the random walks of different pixels are built from the same random numbers. The ...

    • Concise Tour to the Virtual Old Prague 

      Zara, Jiri (Eurographics Association, 2002)
      This paper describes a structure and a user interface of the Internet based 3D presentation of existing historical part of city Prague. The application offers a smooth tour to selected regions of the real city, utilizing ...

    • 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 ...

    • Digital Watermarking for Volumetric Datasets 

      Dimitrov, Leonid I.; Sramek, Milos (Eurographics Association, 2002)
      An idea for digitaly watermarking volumetric datasets (VDS) and preliminary results from a test implementation are presented. It consists of a combination of filtering and rendering operations on volumetric data allowing ...

    • 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 ...

    • 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 ...

    • From Textual Chats to Interest Groups in 3D Virtual Space 

      Masa, Michal; Zara, Jiri (Eurographics Association, 2002)
      While the textual chat is a highly popular tool for various kinds of social interactions, its extension to the visual three-dimensional domain remains almost untouched and without practical utilization yet. This paper ...

    • Dynamic Motion Models 

      Grünvogel, Stefan Michael; Lange, Thorsten; Piesk, Jens (Eurographics Association, 2002)
