  • Distributed Texture Memory in a Multi-GPU Environment 

    Moerschell, Adam; Owens, John D. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    In this work, we demonstrate a system that allows texture memory on multiple graphics processing unit (GPUs) to be virtualized in a manner that is both scalable and transparent to the programmer. Our system is built using ...

  • A Flexible Kernel for Adaptive Mesh Refinement on GPU 

    Boubekeur, T.; Schlick, C. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We present a flexible GPU kernel for adaptive on-the-fly refinement of meshes with arbitrary topology. By simply reserving a small amount of GPU memory to store a set of adaptive refinement patterns, on-the-fly refinement ...

  • A Comparison of Methods for Generating Poisson Disk Distributions 

    Lagae, Ares; Dutre, Philip (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    Poisson disk distributions have many applications in the field of computer graphics. Besides sampling, Poisson disk distributions are used in object distribution, non-photorealistic rendering and procedural texturing. Over ...

  • A Sketch-Based User Interface for Reconstructing Architectural Drawings 

    Lee, Sangwon; Feng, David; Grimm, Cindy; Gooch, Bruce (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We present a framework for interactive sketching that allows users to create three-dimensional (3D) architectural models quickly and easily from a source drawing. The sketching process has four steps. (1) The user calibrates ...

  • Object-Space Visibility Ordering for Point-Based and Volume Rendering 

    Hofsetz, C.; Max, N.; Bastos, R. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    This paper presents a method to accelerate algorithms that need a correct and complete visibility ordering of their data for rendering. The technique works by pre-sorting primitives in object-space using three lists (one ...

  • A General Multi-step Algorithm for Voxel Traversing Along a Line 

    Liu, Y. K.; Song, H. Y.; Zalik, B. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    Traversing voxels along a three dimensional (3D) line is one of the most fundamental algorithms for voxel-based applications. This paper presents a new 6-connectivity integer algorithm for this task. The proposed algorithm ...

  • Pressing: Smooth Isosurfaces with Flats from Binary Grids 

    Chica, A.; Williams, J.; Andujar, C.; Brunet, P.; Navazo, I.; Rossignac, J.; Vinacua, A. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We explore the automatic recovery of solids from their binary volumetric discretizations. In particular, we propose an approach, called Pressing, for smoothing isosurfaces extracted from binary volumes while recovering ...

  • A Dynamic Model of Cracks Development Based on a 3D Discrete Shrinkage Volume Propagation 

    Valette, Gilles; Prevost, Stephanie; Lucas, Laurent; Leonard, Joel (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We attempt to model and visualize the main characteristics of cracks produced on the surface of a desiccating crusted soil: their patterns, their different widths and depths and their dynamics of creation and evolution. ...

  • Point-Based Rendering of Non-Manifold Surfaces 

    Balsys, Ron J.; Suffern, K. G.; Jones, Huw (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We are concerned with producing high-quality images of parametric and implicit surfaces, in particular those with non-manifold features. We present a point-based technique for rendering implicit surfaces that uses octree ...

  • Occlusion Textures for Plausible Soft Shadows* 

    Eisemann, E.; Decoret, X. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    This paper presents a new approach to compute plausible soft shadows for complex dynamic scenes and rectangular light sources. We estimate the occlusion at each point of the scene using prefiltered occlusion textures, which ...

  • Volume and Isosurface Rendering with GPU-Accelerated Cell Projection* 

    Marroquim, R.; Maximo, A.; Farias, R.; Esperanca, C. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We present an efficient Graphics Processing Unit GPU-based implementation of the Projected Tetrahedra (PT) algorithm. By reducing most of the CPU-GPU data transfer, the algorithm achieves interactive frame rates (up to 2.0 ...

  • Real-Time GPU Silhouette Refinement using Adaptively Blended Bezier Patches 

    Dyken, C.; Reimers, M.; Seland, J. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
    We present an algorithm for detecting and extracting the silhouette edges of a triangle mesh in real time using Graphical Processing Units (GPUs). We also propose a tessellation strategy for visualizing the mesh with smooth ...
