  • Expressive Illumination of Foliage Based on Implicit Surfaces 

    Luft, Thomas; Balzer, Michael; Deussen, Oliver (The Eurographics Association, 2007)
    This paper presents an approach for vivid representations of foliage based on implicit surfaces. It approximates the complex lighting interaction within the foliage and enables a clear illustration of its general shape and ...

  • Multi-layered Indirect Texturing for Tree Rendering 

    García, Ismael; Patow, Gustavo; Szirmay-Kalos, László; Sbert, Mateu (The Eurographics Association, 2007)
    This paper presents a technique to render in real time complex trees using billboard clouds as an impostor simplification for the original polygonal tree, combined with a new texture-based representation for the foliage. ...

  • Modeling Trees with a Space Colonization Algorithm 

    Runions, Adam; Lane, Brendan; Prusinkiewicz, Przemyslaw (The Eurographics Association, 2007)
    We extend the open leaf venation model by Runions et al. [RFL*05] to three dimensions and show that it generates surprisingly realistic tree structures. Model parameters correspond to visually relevant tree characteristics ...

  • Fast Fluid Simulation Using Residual Distribution Schemes 

    Sewall, Jason; Mecklenburg, Paul; Mitran, Sorin; Lin, Ming (The Eurographics Association, 2007)
    We present a fast method for physically-based animation of fluids on adaptive, unstructured meshes. Our algo- rithm is capable of correctly handling large-scale fluid forces, as well as their interaction with elastic ...

  • Eulerian Motion Blur 

    Kim, Doyub; Ko, Hyeong-Seok (The Eurographics Association, 2007)
    This paper describes a motion blur technique which can be applied to rendering fluid simulations that are carried out in the Eulerian framework. Existing motion blur techniques can be applied to rigid bodies, deformable ...

  • Real-time Rendering and Animation of Plentiful Flames 

    Bridault, Flavien; Leblond, Michel; Rousselle, François; Renaud, Christophe (The Eurographics Association, 2007)
    Rendering and animating flames in real time is a great challenge because of the complexity of the combustion process. While few models succeeded in simulating a single fire in real time, none tried to handle a large number ...

  • Animating Corrosion and Erosion 

    Wojtan, Chris; Carlson, Mark; Mucha, Peter J.; Turk, Greg (The Eurographics Association, 2007)
    In this paper, we present a simple method for animating natural phenomena such as erosion, sedimentation, and acidic corrosion. We discretize the appropriate physical or chemical equations using finite differences, and we ...

  • Convective Clouds 

    Geist, Robert; Steele, Jay; Westall, James (The Eurographics Association, 2007)
    A new technique for rendering convective clouds is suggested. The technique uses two lattice-Boltzmann (LB) models, one for generating the spatial and temporal distribution of water density and the other for photon transport, ...

  • Goblins by Spheroidal Weathering 

    Beardall, Mathew; Farley, Mckay; Ouderkirk, Darius; Smith, Jeremy; Jones, Michael; Egbert, Parris (The Eurographics Association, 2007)
    Height map models of terrain are computationally efficient but can not represent terrain with concave surfaces. We present an algorithm for generating sandstone goblins using a simulation of spheroidal weathering. Sandstone ...
