    • Spherical Harmonic Lighting of Wavelength-Dependent Phenomena 

      Lindsay, Clifford; Agu, Emmanuel (The Eurographics Association, 2005)
      Rendering of objects that exhibit iridescence has previously been limited to simple lighting conditions generated from a few point or directional lights. We extend this idea by modeling light interference as a Bidirectional ...

      Hoeben, Aldo; Stappers, Pieter Jan (The Eurographics Association, 2005)
      In interactive computer graphics such as games and interactive panoramic photos, users are often presented a view with a larger field of view than would correspond to the distance to and size of the screen on which the ...

    • Interactive Manipulation Of Projections With a Curved Perspective 

      Sudarsanam, Nisha; Grimm, Cindy M; Singh, Karan (The Eurographics Association, 2005)
      The concept of curved perspective has been used by artists such as M.C. Escher in order effectively convey a sense of three dimensional space while being restricted to a two dimensional canvas. We present an interactive ...
    • A 3D Perceptual Metric using Just-Noticeable-Difference 

      Cheng, Irene; Boulanger, Pierre (The Eurographics Association, 2005)
      In multimedia applications, it is essential to distribute resources efficiently among different types of data in order to optimize overall quality. We propose a perceptual metric using Just-Noticeable-Difference (JND) to ...
    • A Visual Quality Prediction Model for 3D Texture 

      Cheng, Irene; Boulanger, Pierre (The Eurographics Association, 2005)
      Online bandwidth limitations and fluctuations impose a major challenge in estimating the amount of data to transmit in a given time period. Over or under estimation of bandwidth can jeopardize the visual fidelity of the ...
    • Progressive Cartesian Inequality Constraints for the Inverse Kinematic Control of Articulated Chains 

      Peinado, Manuel; Boulic, Ronan; Callennec, Benoit Le; Meziat, D. (The Eurographics Association, 2005)
      We propose an Inverse Kinematic Control architecture capable of handling tasks that are expressed in terms of inequality constraints in the Cartesian space. These inequality constraints are progressive in the sense that ...
    • Facial Motion Cloning Using Global Shape Deformation 

      Fratarcangeli, Marco; Schaerf, Marco (The Eurographics Association, 2005)
      We present a novel Facial Motion Cloning method relying on the combination of the radial basis functions (RBF) based scattered data interpolation with the encoding capabilities of the MPEG-4 Facial and Body Animation (FBA) ...
    • Fast Body-Cloth simulation with moving humanoids 

      Rodriguez-Navarro, Javier; Sainz, Miguel; Susin, Antonio (The Eurographics Association, 2005)
      In this paper we present a very fast method for body-cloth animation. The usual bottle-neck in cloth simulation performance is collision detection, which becomes more difficult to solve when a complex geometry, like a human ...
    • Predicting Natural Hair Shapes by Solving the Statics of Flexible Rods 

      Bertails, Florence; Audoly, Basile; Querleux, Bernard; Leroy, Frédéric; Lévêque, Jean-Luc; Cani, Marie-Paule (The Eurographics Association, 2005)
      This paper presents a new physically-based method for predicting natural hairstyles in the presence of gravity and collisions. The method is based upon a mechanically accurate model for static elastic rods (Kirchhoff model), ...
    • Rendering Realistic Trees and Forests in Real Time 

      Candussi, Alberto; Canduss, Nicola; Höllerer, Tobias (The Eurographics Association, 2005)
      Real-Time rendering of realistic trees on common graphics hardware represents a big challenge due to their inherent geometric complexity. In most cases, trees are composed of hundreds of thousands of leaves and branches ...
    • Efficient, Physically Plausible Finite Elements 

      Nesme, Matthieu; Payan, Yohan; Faure, François (The Eurographics Association, 2005)
      This paper discusses FEM-based simulations of soft bodies in terms of speed and robustness. To be physically plausible, three fundamental laws must be respected: rotational invariance, Newton's law and Euler's law. We show ...
    • Leaf Cluster Impostors for Tree Rendering with Parallax 

      Garcia, Ismael; Sbert, Mateu; Szirmay-Kalos, László (The Eurographics Association, 2005)
      This paper presents a simple method to render complex trees on high frame rates while maintaining parallax effects. Based on the recognition that a planar impostor is accurate if the represented polygon is in its plane, ...
