    • Real-Time Procedural Animation of Trees 

      Barron, Jeremy T.; Sorge, Brian P.; Davis, Timothy A. (Eurographics Association, 2001)
      Creating models of living flora, such as trees and grass, has been a challenge in computer graphics for many years. Animating these objects to move realistically in reaction to natural phenomena, such as wind and rain, ...
    • Data driven motion transitions for interactive games 

      Mizuguchi, Mark; Buchanan, John; Calvert, Tom (Eurographics Association, 2001)
      In 3D video games that employ human characters, a series of animations is required to display a character’s motion. The current approach is to use stored animation sequences, either motion captured or hand animated, and ...
    • Metaprogramming for the Generation of Nonparametric Curves 

      Boyer, Vincent (Eurographics Association, 2001)
      One of the most important functions of paintboxes is drawing curves. These primitives have been programmed and the user can never add a new program which computes the discrete points of a given function. Using metaprogramming ...
    • A Visualization System for the Clinical Evaluation of Cerebral Aneurysms from MRA Data 

      Perrin, James S.; Lacey, A.; Laitt, R.; Jackson, A.; John, Nigel W. (Eurographics Association, 2001)
      This paper details a work-in-progress application under development as part of a clinical visualization project. The software has been designed to meet the specific needs of interventional neuro-radiologists evaluating the ...
    • Redirected Walking 

      Razzaque, Sharif; Kohn, Zachariah; Whitton, Mary C. (Eurographics Association, 2001)
      Redirected Walking, a new interactive locomotion technique for virtual environments (VEs), captures the benefits of real walking while extending the possible size of the VE. Real walking, although natural and producing a ...
    • Improvement of the printing model in multi-colored and multi-woodblock virtual printing 

      Mizuno, Shinji; Ushida, Akihide; Okada, Minoru; Toriwaki, Jun-ichiro; Yamamoto, Shinji (Eurographics Association, 2001)
      In this paper, we propose a physically based model for the printing process in the virtual woodblock printing for improvement of printing quality. Virtual printing is a simulation of real printing using “woodblocks”, “a ...
    • Artist Driven Expressive Graphics 

      Mason, Kaye; Carpendale, Sheelagh (Eurographics Association, 2001)
      Current methods in non-photorealistic graphics can place a heavy emphasis on the algorithm, as opposed to the artist. In this paper, we analyse these trends, and present a conceptual framework for putting control back in ...
    • Fractal approximation of surfaces based on projected IFS attractors 

      Guerin, Eric; Tosan, Eric; Baskurt, Atilla (Eurographics Association, 2001)
      A method for approximating smooth or rough surfaces defined in R3 is introduced. A fractal model called projected IFS model allows the extension of the iteration space to a barycentric space Rn2 by enriching the classical ...
    • Warped Textures for UV Mapping Encoding 

      Sorkine, Olga; Cohen-Or, Daniel (Eurographics Association, 2001)
      This paper introduces an implicit representation of the u; v texture mapping. Instead of using the traditional explicit u; v mapping coordinates, a non-distorted piecewise embedding of the triangular mesh is created, on ...
    • Improved Rendering with Dégradé 

      Boyer, Vincent; Sobczyk, Dominique; Bourdin, Jean-Jacques (Eurographics Association, 2001)
      In most paintboxes drawing (and filling) the picture and render the picture are two different steps and tools. Dégradé presents an efficient filling rendering tool: an efficient collection of effect filling. In Dégradé the ...
    • Local Versus Global Triangulations 

      Linsen, Lars; Prautzsch, Hartmut (Eurographics Association, 2001)
      Free form surfaces are commonly represented by triangular or quadrilateral meshes. Often these meshes are obtained from unorganized point sets sampled from some object’s surface. We show that local rather than global ...
    • Scalable Impressionist Rendering 

      Atencia, A.; Bourdin, Jean-Jacques; Boyer, V.; Pissard, T.; Sobczyk, D. (Eurographics Association, 2001)
      The painted impressionist technique produces scale based effects: the far range vision is almost realistic while the close vision is blurred. In NPR, Impressionist Renderers are mainly based on a medium range vision. A ...
    • CORBA Visualization Platform 

      Benoist, Thierry; Hewitt, W. T.; John, Nigel W. (Eurographics Association, 2001)
      -
    • Simplification of implicit skeletal models 

      Lucas, Laurent; Prevost, Stephanie (Eurographics Association, 2001)
      In this paper, we describe a hierarchical representation of unions of balls (UoB) applied to volume graphics. We present an algorithm that generates stable implicit volumes at different levels of resolution in the form of ...
    • Post-rendering Composition for 3D Scenes 

      Grimm, Cindy (Eurographics Association, 2001)
      In traditional art a painter displays a 3D scene on a 2D image plane in a manner that is aesthetically pleasing. The arrangement of objects and colors is called composition and is the subject of many art books and classes. ...
    • Proxy Simulations for Efficient Dynamics 

      Chenney, Stephen; Arikan, Okan; Forsyth, D. A. (Eurographics Association, 2001)
      Proxy simulations reduce the cost of simulation in large virtual worlds, such as those used in training simulations or computer games. A proxy takes the place of an accurate simulation for objects that are out of view, ...
    • Free-Form Deformation of Solid Models in CSR 

      Hui, K. C.; Lai, C.F. (Eurographics Association, 2001)
      Existing free-form deformation (FFD) techniques deform an object by deforming the space enclosing the object. Points on the object are thus deformed relative to the undeformed space (or world space). The deformed object ...
    • An On-line Occlusio-Culling Algorithm for FastWalkthrough in Urban Areas 

      Wang, Yusu; Agarwal, Pankaj K.; Har-Peled, Sariel (Eurographics Association, 2001)
      We describe a fast algorithm to speed up rendering of scenes for walkthroughs in urban environments. Our occlusion culling algorithm takes advantage of temporal coherence in image space. As such, occlusion calculation is ...

      Wu, Fu-Che; Murphy, Chien-Chang Ho; Ouhyoung, Ming (Eurographics Association, 2001)
      An image-based 3-D modeling system is presented in this paper. Our modeling system consists of three main stages: camera calibration, depth estimation and 3-D geometry reconstruction. All of these steps are executed ...
    • Adaptive Progressive Vertex Tracing for Interactive Reflections 

      Ullmann, Thomas; Schmidt, Alexander; Beier, Daniel; Bruderlin, Beat (Eurographics Association, 2001)
      This paper presents an approach for real-time rendering of physically accurate reflection effects in virtual environments. We apply a hybrid rendering of an OpenGL-generated scene, blended with correct reflection characteristics ...
