      Wu, Jainhua; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Using surface splats as a rendering primitive has gained increasing attention recently due to its potential for high-performance and high-quality rendering of complex geometric models. However, as with any other rendering ...

    • A Physically-Based Model for Rendering Realistic Scratches 

      Bosch, Carles; Pueyo, Xavier; Merillou, Stephane; Ghazanfarpour, Djamchid (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Individually visible scratches, also called isolated scratches, are very common in real world surfaces. Although their microgeometry is not visible, they are individually perceptible by the human eye, lying into a ...

    • Point Cloud Collision Detection 

      Klein, Jan; Zachmann, Gabriel (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      In the past few years, many efficient rendering and surface reconstruction algorithms for point clouds have been developed. However, collision detection of point clouds has not been considered until now, although this is ...

    • Procedural Texture Matching and Transformation 

      Bourque, Eric; Dudek, Gregory (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      We present a technique for creating a smoothly varying sequence of procedural textures that interpolates between arbitrary input samples of texture. This texture transformation uses a library of procedural shaders and ...

    • A Progressive Rendering Algorithm Using an Adaptive Perceptually Based Image Metric 

      Farrugia, Jean-Philippe; Peroche, Bernard (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      In this paper, we propose to solve the global illumination problem through a progressive rendering method relying on an adaptive sampling of the image space. The refinement of this sample scheme is driven by an image metric ...

    • Quadric Transfer for Immersive Curved Screen Displays 

      Raskar, Ramesh; van Baar, Jeroen; Willwacher, Thomas; Rao, Srinivas (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Curved screens are increasingly being used for high-resolution immersive visualization environments. We describe a new technique to display seamless images using overlapping projectors on curved quadric surfaces such as ...

    • 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 ...

    • Real-time Rigid Body Simulation for Haptic Interactions Based on Contact Volume of Polygonal Objects 

      Hasegawa, S.; Sato, M. (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      This paper proposes a new method for real-time rigid body simulations for haptic interactions based on a penalty method regarding contact volume. Analytical methods for calculation of contact forces require too much time ...

    • 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 ...

    • Scalable behaviors for crowd simulation 

      Sung, Mankyu; Gleicher, Michael; Chenney, Stephen (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Crowd simulation for virtual environments offers many challenges centered on the trade-offs between rich behavior, control and computational cost. In this paper we present a new approach to controlling the behavior of ...

    • 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 ...
