    • Articulated Video Sprites 

      Vanaken, C.; Gerrits, M.; Bekaert, P. (The Eurographics Association, 2006)
      In this paper, we present an extension to video sprites for articulated characters. Central to our technique is a matching cost which works on high-level 2D skeletal representations of the characters, instead of their ...

    • Automatic Depth-Map Colorization 

      Hassner, T.; Basri, R. (The Eurographics Association, 2006)
      We present a system for automatically generating custom, structured image-maps for input depth-maps. Our system thus allows quick fitting of masses of objects with tailor-made image-maps. Given a depth-map of a novel 3D ...

    • Clothing the Masses: Real-Time Clothed Crowds With Variation 

      Dobbyn, S.; McDonnell, R.; Kavan, L.; Collins, S.; O'Sullivan, C. (The Eurographics Association, 2006)
      The animation and rendering of crowds of realistically clothed characters presents a difficult challenge in computer graphics, which is further exacerbated when real-time frame rates are required. To date, due to real-time ...

    • Competitive Runtime Performance for Inverse Kinematics Algorithms using Conformal Geometric Algebra 

      Hildenbrand, Dietmar; Fontijne, Daniel; Wang, Yusheng; Alexa, Marc; Dorst, Leo (The Eurographics Association, 2006)
      Conformal geometric algebra is a powerful tool to find geometrically intuitive solutions. We present an approach for the combination of compact and elegant algorithms with the generation of very efficient code based on two ...

    • Connectivity-Aware Sectional Visualization of 3D DTI Volumes using Perceptual Flat-Torus Coloring and Edge Rendering 

      Demiralp, Çagatay; Zhang, Song; Tate, David F.; Correia, Stephen; Laidlaw, David H. (The Eurographics Association, 2006)
      We present two new methods for visualizing cross-sections of 3D diffusion tensor magnetic resonance imaging (DTI) volumes. For each of the methods we show examples of visualizations of the corpus callosum in the midsagittal ...

    • Digital HPO Hologram Rendering Pipeline 

      Janda, M.; Hanák, I.; Skala, V. (The Eurographics Association, 2006)
      This paper describes a rendering pipeline for digital hologram synthesis. The pipeline is capable of handling triangle meshes, directional light sources, texture coordinates, and advanced illumination models. Due to the ...

    • Dynamic Anisotropic Occlusion 

      Gong, Yi; Zhang, Yubo; Chen, Wei; Peng, Qunsheng (The Eurographics Association, 2006)
      We present a new real-time shadow rendering approach whose kernel is a hierarchical disk-based approximation to the scene geometry. We show that this approximated representation greatly accelerates the visibility inquiry, ...

    • Elastic Facial Caricature Warping 

      Clarke, Lyndsey; Chen, Min; Townsend, Peter; Mora, Benjamin (The Eurographics Association, 2006)
      Caricatures are usually created by skilled artists, and, due to their amusing appearance, they serve mainly as a source of entertainment and humour. This short paper is therefore concerned with a means for generating facial ...

    • Enhanced Cartoon and Comic Rendering 

      Spindler, Martin; Röber, Niklas; Döhring, Robert; Masuch, Maic (The Eurographics Association, 2006)
      In this work we present an extension to common cel shading techniques, and describe four new cartoon-like rendering styles applicable for real-time implementations: stylistic shadows, double contour lines, soft cel shading, ...

    • Evaluation of Different Diffuse Surface Reflection Models for Global Illumination 

      Diepstraten, Joachim; Borgo, Rita (The Eurographics Association, 2006)
      One common goal nearly all global illumination algorithms aim for is solving the light transport problem. The most visual noticeable one in the general case is the diffuse-diffuse light transport between surfaces. Most ...

    • Exploring Flow Fields with GPU-Based Stream Tracers in Virtual Environments 

      Schirski, Marc; Bischof, Christian; Kuhlen, Torsten (The Eurographics Association, 2006)
      In this paper we present an immersive visualization approach for the intuitive exploration of flow fields, which operates entirely within the graphics subsystem. We augment particle data with a brief history of their recent ...

    • Fast and Realistic Display of Clouds Using a Recording Matrix 

      Wu, Y.; Allgöwer, B.; Nüesch, D. (The Eurographics Association, 2006)
      For volumetric cloud models, traditional ray tracing methods and graphics hardware acceleration methods can result in photorealistic images, but with considerably expensive costs. Hence, real-time rendering can be achieved ...

    • Fast Skeletal Animation by skinned Arc-Spline based Deformation 

      Forstmann, Sven; Ohya, Jun (The Eurographics Association, 2006)
      Presented is a novel skeletal animation system for providing high quality geometric deformations in real-time. Each bone of the skeleton is therefore represented by a spline, rather than using conventional matrix rotation. ...

    • GPU-Based Hierarchical Texture Decompression 

      Stachera, J.; Rokita, P. (The Eurographics Association, 2006)
      We propose a hierarchical texture compression algorithm for real-time decompression on the GPU. Our algorithm is characterized by low computational complexity, random access and hierarchical structure which allow us to ...

    • Harnessing the Human Visual System for Image Based Modeling: an Interaction System 

      Morvan, Y.; O'Sullivan, C. (The Eurographics Association, 2006)
      We present a novel interaction system for modeling 3D geometry from photographs. Given a set of stereo pairs, along with their camera parameters, the interface tracks the movements of the users and allows them to intuitively ...

    • High Quality Shadows for Real-Time Crowds 

      Ryder, G.; Day, A. M. (The Eurographics Association, 2006)
      Real-time shadowed crowds, especially under locally lit environments, pose several distinct challenges. Current solutions for crowds are either very simplistic for multiple lights or only handle a single directional light ...
