      Zach, Christopher; Klaus, Andreas; Hadwiger, Markus; Karner, Konrad (Konrad, 2003)
      Vertex programs and pixel shaders found in modern graphics hardware are commonly used to enhance the realism of rendered scenes. Recently these hardware facilities were exploited to obtain interactive non-photorealistic ...
    • ActiveInk 

      Tobita, Hiroaki; Rekimoto, Jun (Eurographics Association, 2003)
      The ActiveInk system integrates the advantages of real world painting techniques with computer graphics (CG) effects such as natural phenomenon animations (e.g., water, fire, snow, and clouds), attributes (e.g., rubber, ...
    • Adaptive quantization with error bounds for compressed view-dependent multiresolution meshes 

      Grabner, Markus; Zach, Christopher (Eurographics Association, 2003)

      Focus of this talk: • Per-pixel point light Blinn-Phong lighting • Per-pixel realistic metal-BRDF • Per-pixel anisotropic lighting • Procedural textures • Different reflection/environment mapping techniques • “Faked“ translucency
    • Alternative Augmented Reality Approaches: Concepts, Techniques, and Applications 

      Bimber, Oliver; Raskar, Ramesh (Eurographics Association, 2003)
      In this tutorial we discuss application specific alternative augmented reality (AR) approaches –such as Virtual Showcases and Shader Lamps– that focus on overcoming some of the limitations linked to conventional AR displays. ...
    • Animating Tree Movement with Sound Effects Generation 

      Matsuyama, Katsutsugu; Ota, Shin; Tamura, Machiko; Fujimoto, Tadahiro; Muraoka, Kazunobu; Chiba, Norishige (Eurographics Association, 2003)
      This video demonstrates the methods for automatically generating tree motions and sound effects for an animation of branches and leaves moving in the wind. Natural motions of leaves and branches swaying in a wind field are ...
    • Animatope: A Manga-Styled Animation Expression Toolkit 

      Tohda, Asuka; Hasegawa, Sho; Inakage, Masa (Eurographics Association, 2003)
      Manga, a Japanese comic style, is becoming widely accepted within comic readers worldwide. In Manga, mimetic symbols and onomatopoeia symbols are heavily used to express emotions and various movements in a comic frame. In ...
    • Anisotropic Participating Media at Near Interactive Rates 

      Jimenez, Juan-Roberto; Pueyo, Xavier (Eurographics Association, 2003)
      This article presents an algorithm for the realistic simulation, at near interactive rates, of globally illuminated scenes including participating media, isotropic and anisotropic. The proposed algorithm is divided in three ...
    • Ashli – Advanced Shading Language Interface 

      Preetham, Arcot J.; Bleiweiss, Avi (Eurographics Association, 2003)
      The support for IEEE floating point computation and the exposure of shading functionality in a standardize API form have made graphics hardware a viable workflow solution to an artist involved in digital content creation ...
    • Automatic High Level Avatar Guidance Based on Affordance of Movement 

      Michael, Despina; Chrysanthou, Yiorgos (Eurographics Association, 2003)
      As virtual cities become ever more common and more extensive, the need to populate them with virtual pedestrians grows. One of the problems to be resolved for the virtual population is the behaviour simulation. Currently ...
    • Beyond Image Quality Comparison 

      Bornik, Alexander; Cech, Peter; Ferko, Andrej; Perko, Roland (Eurographics Association, 2003)
      We solve the problem of quantitative measuring of image quality, beyond the widely used MSE (mean square error) or even visual comparison. We combine eight feature-based and perceptually-oriented image quality metrics. The ...
