    • 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 ...
