    • Simulating and modeling lichen growth 

      Desbenoit, Brett; Galin, Eric; Akkouche, Samir (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      This paper presents a system for modeling lichens and simulating their propagation and growth in a virtual scene. Lichens colonize almost every substrate in nature and play an important role in the visual appearance of a ...

    • SMARTPAPER: An Interactive and User Friendly Sketching System 

      Shesh, Amit; Chen, Baoquan (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      This paper describes an interactive sketching system for 3D design/modeling that diverts from the conventional menu-and-button interfaces of CAD tools. The system, dubbed SMARTPAPER, offers a unified sketching environment ...

    • Fast Surface Modelling Using a 6th Order PDE 

      Zhang, Jian. J.; You, L. H. (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Although the control-point based parametric approach is used most widely in free-form surface modelling, complementary techniques co-exist to meet various specialised requirements. The partial differential equation (PDE) ...

    • Dupin Cyclide Blends Between Quadric Surfaces for Shape Modeling 

      Foufou, Sebti; Garnier, Lionel (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      We introduce a novel method to define Dupin cyclide blends between quadric primitives. Dupin cyclides are non-spherical algebraic surfaces discovered by French mathematician Pierre-Charles Dupin at the beginning of the ...

    • Rendering with Spherical Radiance Transport Maps 

      Mei, Chunhui; Shi, Jiaoying; Wu, Fuli (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      In this paper, we propose a real-time method for rendering soft shadows and inter-reflections of dynamic objects under complex illumination. In previous methods, many efforts were taken to acquire occlusion and reflection ...

    • Real-time Light Animation 

      Sbert, Mateu; Szecsi, Laszlo; Szirmay-Kalos, Laszlo (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Light source animation is a particularly hard field of real-time global illumination algorithms since moving light sources result in drastic illumination changes and make coherence techniques less effective. However, the ...

    • Approximate Soft Shadows win an Image-Space Flood-Fill Algorithm 

      Arvo, Jukka; Hirvikorpi, Mika; Tyystjaervi, Joonas (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Most former soft shadow algorithms have either suffered from restricted self-shadowing capabilities, been too slow for interactive applications, or could only be used with a limited types of geometry. In this paper, we ...

    • Smooth Surface Reconstruction Using Tensor Fields as Structuring Elements 

      Vieira, M. B.; Martins, P. P.; Araujo, A. A.; Cord, M.; Philipp-Foliguet, S. (The Eurographics Association and Blackwell Publishing Ltd., 2004)
      We propose a new strategy to estimate surface normal information from highly noisy sparse data. Our approach is based on a tensor field morphologically adapted to infer normals. It acts as a three-dimensional structuring ...

    • Stellar Mesh Simplification Using Probabilistic Optimization 

      Antonio W. Vieira; Thomas Lewiner; Luiz Velho; Helio Lopes; Geovan Tavares (The Eurographics Association and Blackwell Publishing Ltd., 2004)

    • Physical Validation of Global Illumination Methods: Measurement and Error Analysis 

      Roland Schregle; Jan Wienold (The Eurographics Association and Blackwell Publishing Ltd., 2004)
      In this paper, we present a physical validation of global illumination algorithms based on measurements from a simple experimental setup. The validation methodology emphasizes tractability and error minimization. To this ...

    • Para-Graph: Graph-Based Parameterization of Triangle Meshes with Arbitrary Genus 

      Giuseppe Patane; Michela Spagnuolo; Bianca Falcidieno (The Eurographics Association and Blackwell Publishing Ltd., 2004)
      This paper describes a novel approach to the parameterization of triangle meshes representing 2-manifolds with an arbitrary genus. A topology-based decomposition of the shape is computed and used to segment the shape into ...

    • Style-Based Motion Synthesis 

      Raquel Urtasun; Pascal Glardon; Ronan Boulic; Daniel Thalmann; Pascal Fua (The Eurographics Association and Blackwell Publishing Ltd., 2004)
      Representing motions as linear sums of principal components has become a widely accepted animation technique. While powerful, the simplest version of this approach is not particularly well suited to modeling the specific ...

    • Compression of Large-Scale Terrain Data for Real-Time Visualization Using a Tiled Quad Tree 

      Platings, M.; Day, A. M. (The Eurographics Association and Blackwell Publishing Ltd., 2004)
      The aim of the rapid world modeling project is to implement a system to visualize the topography of the entire world on consumer-level hardware. This presents a significant problem in terms of both storage requirements and ...

    • Fast Hybrid Approach for Texturing Point Models 

      Haitao Zhang; Feng Qiu; Arie Kaufman (The Eurographics Association and Blackwell Publishing Ltd., 2004)
      We present three methods for texturing point models from sample textures. The first method, the point parameterization method, uses a fast distortion-bounded parameterization algorithm to flatten the point model's surface ...

    • Placement of Deformable Objects 

      S. Schein; G. Elber (The Eurographics Association and Blackwell Publishing Ltd., 2004)
      With the increasing complexity of photorealistic scenes, the question of building and placing objects in three-dimensional scenes is becoming ever more difficult. While the question of placement of rigid objects has captured ...
