    • Realistic and Interactive Visualization of High-Density Plant Ecosystems 

      Dietrich, Andreas; Colditz, Carsten; Deussen, Oliver; Slusallek, Philipp (The Eurographics Association, 2005)
      Modeling and visualization of natural and realistic outdoor ecosystems like forests or meadows remains a highly challenging task in computer graphics. Convincing and non-artificial scenes require many thousands to millions ...

    • Synthesis of Material Drying History: Phenomenon Modeling, Transferring and Rendering 

      Lu, Jianye; Georghiades, Athinodoros S.; Rushmeier, Holly; Dorsey, Julie; Xu, Chen (The Eurographics Association, 2005)
      We consider the problem of the spatio-temporal variations in material appearance due to the wetting and drying of materials. We conducted a series of experiments that capture the appearance history of surfaces drying. We ...

    • Extreme Model Simplification for Forest Rendering 

      Fuhrmann, Anton L.; Umlauf, Eike; Mantler, Stephan (The Eurographics Association, 2005)
      Models of large forest scenes are of a geometric complexity that surpasses even the capabilities of current high end graphics hardware. We propose an extreme simplification method which allows us to render such scenes in ...

    • Point-based Rendering of Trees 

      Gilet, Guillaume; Meyer, Alexandre; Neyret, Fabrice (The Eurographics Association, 2005)
      The goal of this paper is the interactive and realistic rendering of 3D trees covering a landscape. The landscape is composed by instantiating one or more block of vegetation on the terrain. A block of vegetation is composed ...

    • A Preliminary Approach of 3D Simulation of Soil Surface Degradation by Rainfall 

      Valette, Gilles; Herbin, Michel; Lucas, Laurent; Léonard, Joël (The Eurographics Association, 2005)
      Soil surface structure and morphology deeply in uence a lot of processes of high agronomic and environmental relevance, such as mass and heat transfer through the soil-atmosphere interface, runoff and erosion, seed germination ...

    • Interactive physically based Fluid and Erosion Simulation 

      Neidhold, B.; Wacker, M.; Deussen, O. (The Eurographics Association, 2005)
      Realistically eroded terrain is a base of almost every outdoor visualization for simulators or computer games. In order to achieve convincing results physically based erosion algorithms are necessary. We present a new ...

    • Phenomenological Simulation of Efflorescence in Brick Constructions 

      Shahidi, S.; Merillou, S.; Ghazanfarpour, D. (The Eurographics Association, 2005)
      In human constructions, repetitive patterns can be handled by different texturing methods. However, almost all techniques do not consider weathering phenomena, missing a very important visual effect for realistic rendering. ...

    • Modeling and Visualization of symmetric and asymmetric plant competition 

      Alsweis, M.; Deussen, O. (The Eurographics Association, 2005)
      In this paper we describe a new method for the visual simulation of evolving plant communities, which involves, aside from the known symmetric competition for resources also asymmetric competition. Asymmetric competition ...

    • Table Mountains by Virtual Erosion 

      Bene , B.; Arriaga, X. (The Eurographics Association, 2005)
      We present an ef cient algorithm for visual modeling table mountains (mesas) using erosion simulation. The method uses techniques from Computer Graphics to closely model the phenomenon, without relying on physically correct ...

    • FlowFixer: Using BFECC for Fluid Simulation 

      Kim, ByungMoon; Liu, Yingjie; Llamas, Ignacio; Rossignac, Jarek (The Eurographics Association, 2005)
      Back and Forth Error Compensation and Correction (BFECC) was recently developed for interface computation by using the level set method. We show that it can be applied to reduce dissipation and diffusion encountered in ...
