    • Automatic Generation of Animated Population in Virtual Environments 

      Thalmann, D.; Magnenat-Thalmann, N.; Donikian, S. (Eurographics Association, 2004)
      The necessity to model virtual population appears in many applications of computer animation and simulation. Such applications encompass several different domains - representative or autonomous agents in virtual environments, ...

    • Modern Approaches to Augmented Reality 

      Bimber, Oliver; Raskar, Ramesh (Eurographics Association, 2004)
      This tutorial provides a survey of modern techniques for augmented reality (AR) systems. Novel approaches have taken AR beyond traditional eye-worn or hand-held displays, enabling new application areas. We discuss conventional ...

    • RenderWare: Speed up the 3D Application Production Pipeline 

      Guilbert, Oskar (Eurographics Association, 2004)
      The presentation gives the big picture for Criterion Software and how the Renderware technology provided by Criterion is used in the game industry. RenderWare's applications-authoring frame work will then be presented.

    • Geometric Algebra and its Application to Computer Graphics 

      Hildenbrand, Dietmar; Perwass, Christian; Dorst, Leo; Fontijne, Daniel (Eurographics Association, 2004)
      In this tutorial we will give an overview of Geometric Algebra and its application to computer graphics. First of all, we want to motivate the topic and give insights into some applications.

      Magnenat-Thalmann, N.; Cordier, F.; Keckeisen, M.; Kimmerle, S.; Klein, R.; Meseth, J. (Eurographics Association, 2004)
      This presentation gives an overview of the whole tutorial. It introduces the different techniques that will be presented in the next sessions. An overview of previous work is given as well.

    • A Quick and Automatic Image Based Modeling and Rendering System 

      Yerex, Keith; Birkbeck, Neil; Cobzas, Dana; Jagersand, Martin (Eurographics Association, 2004)
      We present a complete and automatic system for object capture from video, Internet delivery, and real-time photorealistic rendering. Shape from silhouette is used to capture an approximate enveloping geometry, the visual ...

    • Adaptive Brush Stroke Generation for Painterly Rendering 

      Park ChungAng, Youngsup; Yoon, Kyunghyun (Eurographics Association, 2004)
      We propose adaptive brush stroke generation for source images, using reference data. Colors used are formed by actual palette colors from artists. To create the palette, we have referred mostly to colors used in Van Gogh’s ...

    • Realtime Isosurface Extraction with Graphics Hardware 

      Reck, Frank; Dachsbacher, Carsten; Grosso, Roberto; Greiner, Günther; Stamminger, Marc (Eurographics Association, 2004)
      In this paper we introduce a method for the display of isosurfaces extracted from unstructured tetrahedral grids. Our algorithm completely runs on the graphics hardware. The tetrahedra are streamed into a vertex program, ...

    • Collision Detection for Deformable Objects 

      Teschner, M.; Kimmerle, S.; Heidelberger, B.; Zachmann, G.; Raghupathi, L.; Fuhrmann, A.; Cani, M.-P.; Faure, F.; Magnenat-Thalmann, N.; Strasser, W.; Volino, P. (Eurographics Association, 2004)
      Interactive environments for dynamically deforming objects play an important role in surgery simulation and entertainment technology. These environments require fast deformable models and very efficient collision handling ...

    • Perceptually Adaptive Graphics 

      O’Sullivan, Carol; Howlett, Sarah; McDonnell, Rachel; Morvan, Yann; O’Conor, Keith (Eurographics Association, 2004)
      In recent years, the Graphics community has come to realise the importance of taking human perception into account when striving for realism in images, animations and Virtual Environments. In May 2001, a EUROGRAPHICS/ ...

    • Modulating View-dependent Textures 

      Jagersand, Martin; Cobzas, Dana; Yerex, Keith (Eurographics Association, 2004)
      We present a texturing approach for image-based modeling and rendering, where instead of using one (or a blend of a few) sample images, new view dependent textures are synthesized by modulating a differential texture basis. ...

    • A Generic Method for Geometric Contraints Detection 

      Salvati, Marc; Lecallennec, Benoît; Boulic, Ronan (Eurographics Association, 2004)
      In this paper, we present a generic method to automatically detect geometric constraints on motion capture animations. At each frame, elementary geometric constraints are computed with respect to a reference which can ...
