    • Particle-Based Simulation of Fluids 

      Premzoe, Simon; Tasdizen, Tolga; Bigler, James; Lefohn, Aaron; Whitaker, Ross T. (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      Due to our familiarity with how fluids move and interact, as well as their complexity, plausible animation of fluidsremains a challenging problem. We present a particle interaction method for simulating fluids. The ...

    • Fast Photo-Realistic Rendering of Trees in Daylight 

      Qin, Xueying; Nakamae, Eihachiro; Tadamura, Katsumi; Nagai, Yasuo (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      We propose a fast approach for photo-realistic rendering of trees under various kinds of daylight, which is particularlyuseful for the environmental assessment of landscapes. In our approach the 3D tree models are transformedto ...

    • Cloth Motion Capture 

      Pritchard, D.; Heidrich, W. (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      Recent years have seen an increased interest in motion capture systems. Current systems, however, are limitedto only a few degrees of freedom, so that effectively only the motion of linked rigid bodies can be acquired. ...

    • Compression of 2D Vector Fields Under Guaranteed Topology Preservation 

      Theisel, H.; Rossl, Ch.; Seidel, H.-P. (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      In this paper we introduce a new compression technique for 2D vector fields which preserves the complete topology, i.e., the critical points and the connectivity of the separatrices. As the theoretical foundation of the ...

    • Multi-scale Feature Extraction on Point-Sampled Surfaces 

      Pauly, Mark; Keiser, Richard; Gross, Markus (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      We present a new technique for extracting line-type features on point-sampled geometry. Given an unstructuredpoint cloud as input, our method first applies principal component analysis on local neighborhoods toclassify ...

    • Open Issues in Photo-realistic Rendering 

      Purgathofer, Werner (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      For more than two decades Computer graphics researchers have tried to achieve photo-realism in their images as reliable as possible, mainly by simulating the physical laws of light and adding one effect after the other. ...

    • Planning Collision-Free Reaching Motions for Interactive Object Manipulation and Grasping 

      Kallmann, Marcelo; Aubel, Amaury; Abaci, Tolga; Thalmann, Daniel (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      We present new techniques that use motion planning algorithms based on probabilistic roadmaps to control 22 degrees of freedom (DOFs) of human-like characters in interactive applications. Our main purpose is the automatic ...

    • Field Functions for Blending Range Controls on Soft Objects 

      Hsu, P. C.; Lee, C. (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      This paper proposes new field functions that have adjustable inner radius and outer radius of influence. Incorporatingthe proposed field functions with soft object modeling, soft blending, Ricci's super-ellipsoid blends, ...

    • 3D Video Recorder: a System for Recording and Playing Free-Viewpoint Video? 

      Wurmlin, Stephan; Lamboray, Edouard; Staadt, Oliver G.; Gross, Markus H. (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      We present the 3D Video Recorder, a system capable of recording, processing, and playing three-dimensional video from multiple points of view. We first record 2D video streams from several synchronized digital video cameras ...

    • Interactive Rendering of Translucent Objects? 

      Lensch, Hendrik P.A.; Goesele, Michael; Bekaert, Philippe; Kautz, Jan; Magnor, Marcus A. and Lang, Jochen and Seidel, Hans-Peter (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      This paper presents a rendering method for translucent objects, in which viewpoint and illumination can be modified at interactive rates. In a preprocessing step, the impulse response to incoming light impinging at each ...

    • The Scale Method for Blending Operations in Functionally-Based Constructive Geometry 

      Hsu, P.-C.; Lee, C. (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      This paper presents a scale method for developing high dimensional scale functions to blend implicitly defined objects. Scale functions are differentiable on the entire domain except the origin, provide blending range ...

    • Efficient Modeling of An Anatomy-Based Face and Fast 3D Facial Expression Synthesis 

      Zhang, Yu; Prakash, Edmond C.; Sung, Eric (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      This paper presents new methods for efficient modeling and animation of an hierarchical facial model that conforms to the human face anatomy for realistic and fast 3D facial expression synthesis. The facial model has a ...

    • Approximating Parametric Curves With Strip Trees Using Affine Arithmetic 

      Henrique de Figueiredo, Luiz; Stolfi, Jorge; Velho, Luiz (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      We show how to use affine arithmetic to represent a parametric curve with a strip tree. The required bounding rectangles for pieces of the curve are computed by exploiting the linear correlation information given by affine ...

    • Local Exact Particle Tracing on Unstructured Grids 

      Kipfer, Peter; Reck, Frank; Greiner, Gunther (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      For analyzing and interpreting results of flow simulations, particle tracing is a well established visualization method. In addition, it is a preliminary step for more advanced techniques such as line integral convolution. ...

    • Recent Developments and Applications of Haptic Devices 

      Laycock, S. D.; Day, A. M. (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      Over recent years a variety of haptic feedback devices have been developed and are being used in a number of important applications. They range from joysticks used in the entertainment industry to specialised devices used ...
