  • Hong, Jeong-Mo; Kim, Chang-Hun (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    We present a new fluid animation technique in which liquid and gas interact with each other, using the exampleof bubbles rising in water. In contrast to previous studies which only focused on one fluid, our system considersboth ...
  • Kobbelt, Leif (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    The most important concepts for the handling and storage of freeform shapes in geometry processing applications are parametric representations and volumetric representations. Both have their specific advantages and drawbacks. ...
  • Sousa, Mario Costa; Prusinkiewicz, Przemyslaw (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    We present a method for rendering 3D models in the traditionalline-drawing style used in artistic and scientificillustrations. The goal is to suggest the 3D shape of the objectsusing a small number of lines drawn with ...
  • Bischoff, Stephan; Kobbelt, Leif (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    Active contour models are an efficient, accurate, and robust tool for the segmentation of 2D and 3D image data.In particular, geometric deformable models (GDM) that represent an active contour as the level set of an ...
  • Navazo, I.; Rossignac, J.; Jou, J.; Shariff, R. (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    We present a novel Cell-To-Cell Visibility (C2CV) algorithm, which given two polyhedra, AandBand a connectedand oriented manifold triangle mesh, S offers a simple, fast and conservative test for detecting when A and B ...
  • Rieger, Thomas; Braun, Norbert (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    This paper describes the concept and control of a 3d virtual character system with facial expressions and gesturesas a conversational user interface with narrative expressiveness for the hearing impaired. The gestures and ...
  • Blanz, V.; Basso, C.; Poggio, T.; Vetter, T. (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    This paper presents a method for photo-realistic animation that can be applied to any face shown in a single imageor a video. The technique does not require example data of the person's mouth movements, and the image to ...
  • Kshirsagar, Sumedha; Magnenat-Thalmann, Nadia (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    Visemes are visual counterpart of phonemes. Traditionally, the speech animation of 3D synthetic faces involvesextraction of visemes from input speech followed by the application of co-articulation rules to generate ...
  • Benthin, Carsten; Wald, Ingo; Slusallek, Philipp (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    The addition of global illumination can dramatically increase the realism achievable when rendering virtual environments.In particular with interactive applications we expect the environment to reflect changes in the ...
  • Iwasaki, Kei; Dobashi, Yoshinori; Nishita, Tomoyuki (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    In order to synthesize realistic images of scenes that include water surfaces, the rendering of optical effectscaused by waves on the water surface, such as caustics and reflection, is necessary. However, rendering causticsis ...
  • Wand, M.; Strasser, W. (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    We present a new algorithm to render caustics. The algorithm discretizes the specular surfaces into samplepoints. Each of the sample points is treated as a pinhole camera that projects an image of the incoming lightonto ...
  • Boudon, Frederic; Prusinkiewicz, Przemyslaw; Federl, Pavol; Godin, Christophe; Karwowski, Radoslaw (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    Because of their complexity, plant models used in computer graphics are commonly created with proceduralmethods. A difficult problem is the user control of these models: a small number of parameters is insufficient tospecify ...
  • Evers-Senne, J.-F.; Koch, R. (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    In this paper we present a novel approach for interactive rendering of virtual views from real image sequences.Combining the concepts of light fields, depth-compensated image warping and view dependent texture mapping,this ...
  • Tarrin, N.; Coquillart, S.; Hasegawa, S.; Bouguila, L.; Sato, M. (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    The workbench is an interesting semi-immersive configuration for interactive tasks. However, haptic feedback, i.e.force and tactile feedback, is one important cue which is missing. To the authors' knowledge, the sole ...
  • Gobbetti, Enrico; Spano, Leonardo; Agus, Marco (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    We present an algorithm for simulating global illumination in scenes composed of highly tessellated objects withdiffuse or moderately glossy reflectance. The solution method is a higher order extension of the face cluster ...
  • Xu, Songhua; Lau, Francis C.M.; Tang, Feng; Pan, Yunhe (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    This paper proposes a novel algorithmic framework for an advanced virtual brush to be used in interactive digitalpainting. The framework comprises the following components: a geometry model of the brush using a ...
  • Christensen, Per H.; Laur, David M.; Fong, Julia; Wooten, Wayne L.; Batali, Dana (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    When rendering only directly visible objects, ray tracing a few levels of specular reflection from large, low-curvaturesurfaces, and ray tracing shadows from point-like light sources, the accessed geometry is coherentand ...
  • Müller, Kerstin; Techmann, Torsten; Fellner, Dieter W. (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    Subdivision Surfaces as well as (interactive) ray tracing have become an important issue in computer graphics.But ray tracing of subdivision surfaces has received only little attention. We present a new approach for ...
  • Bajaj, Chandrajit (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    The 3D structures of individual proteins or small complexes, such as most of the Protein Data Bank entries, are still unable to yield the 'full picture' of a functional biological complex. The study of large macromolecular ...
  • Diepstraten, J.; Weiskopf, D.; Ertl, T. (Blackwell Publishers, Inc and the Eurographics Association, 2003)
    In this paper we discuss different approaches to generate cutaway illustrations. The purpose of such a drawingis to allow the viewer to have a look into an otherwise solid opaque object. Traditional methods to draw thesekinds ...
