  • SPAF: Sub-texel Precision Anisotropic Filtering 

    Shin, Hyun-Chul; Lee, Jin-Aeon; Kim, Lee-Sup (The Eurographics Association, 2001)
    Texture mapping is a technique which most effectively improves the realism of computer-generated scenes in 3D Graphics. Trilinear filtering of the mip-mapped textue has been popular as a texture filtering method but it ...

  • Real-Time Bump Map Synthesis 

    Kautz, Jan; Heidrich, Wolfgang; Seidel, Hans-Peter (The Eurographics Association, 2001)
    In this paper we present a method that automatically synthesizes bump maps at arbitrary levels of detail in real-time. The only input data we require is a normal density function; the bump map is generated according to ...

  • Vertex-based Anisotropic Texturing 

    Olano, Marc; Mukherjee, Shrijeet; Dorbie, Angus (The Eurographics Association, 2001)
    MIP mapping is a common method used by graphics hardware to avoid texture aliasing. In many situations, MIP mapping over-blurs in one direction to prevent aliasing in another. Anisotropic texturing reduces this blurring ...

  • Perlin Noise Pixel Shaders 

    Hart, John C. (The Eurographics Association, 2001)
    While working on a method for supporting real-time procedural solid texturing, we developed a general purpose multipass pixel shader to generate the Perlin noise function. We implemented this algorithm on SGI workstations ...

  • Quasi-Linear Depth Buffers With Variable Resolution 

    Lapidous, Eugene; Jiao, Guofang; Zhang, Jianbo; Wilson, Timothy (The Eurographics Association, 2001)
    In this paper we present new class of variable-resolution depth buffers, providing a flexible trade-off between depth precision in the distant areas of the view volume and performance. These depth buffers can be implemented ...

  • R-Buffer: A Pointerless A-Buffer Hardware Architecture 

    Wittenbrink, Craig M. (The Eurographics Association, 2001)
    We present a graphics hardware architecture that implements Carpenter's A-buffer. The A-buffer is a software renderer that uses pointer based linked lists. Our pointerless approach computes order independent transparency ...

  • Incremental and Hierarchical Hilbert Order Edge Equation Polygon Rasterization 

    McCool, Michael D.; Wales, Cluis; Moule, Kevin (The Eurographics Association, 2001)
    A rasterization algorithm must efficiently generate pixel fragments from geometric descriptions of primitives. ln order to accomplish per-pixel shading, shading parameters must also be interpolated across the primitive in ...

  • The F-Buffer: A Rasterization-Order FIFO Buffer for Multi-Pass Rendering 

    Mark, William R.; Proudfoot, Kekoa (The Eurographics Association, 2001)
    Multi-pass rendering is a common method of virtualizing graphics hardware to overcome limited resources. Most current multi-pass rendering techniques use the RGBA framebuffer to store intermediate results between each pass. ...

  • Hardware Support for Non-photorealistic Rendering 

    Raskar, Ramesh (The Eurographics Association, 2001)
    Special features such as ridges, valleys and silhouettes, of a polygonal scene are usually displayed by explicitly identifying and then rendering 'edges' for the corresponding geometry. The candidate edges are identified ...

  • Compiling to a VLIW Fragment Pipeline 

    Mark, William R.; Proudfoot, Kekoa (The Eurographics Association, 2001)
    The latest generation of graphics hardware supports fully programmable vertex and pixel/fragment operations, but programming this hardware at a low level is difficult and time consuming. To address this problem, we have ...

  • Watertight Tessellation using Forward Differencing 

    Moreton, Henry (The Eurographics Association, 2001)
    In this paper we describe an algorithm and hardware for the tessellation of polynomial surfaces. While conventional forward difference-based tessellation is subject to round off error and cracking, our algorithm produces ...

  • Hardware Support for Adaptive Subdivision Surface Rendering 

    Boo, M.; Amor, M.; Doggett, M.; Hirche, J.; Strasser, W. (The Eurographics Association, 2001)
    Adaptive subdivision of triangular meshes is highly desirable for surface generation algorithms including adaptive displacement mapping in which a highly detailed model can be constructed from a coarse triangle mesh and a ...

  • Fast Volumetric Deformation On General Purpose Hardware 

    Rezk-Salama, C.; Scheuering, M.; Soza, G.; Greiner, G. (The Eurographics Association, 2001)
    High performance deformation of volumetric objects is a common problem in computer graphics that has not yet been handled sufficiently. As a supplement to 3D texture based volume rendering, a novel approach is presented, ...

  • High-Quality Pre-lntegrated Volume Rendering 

    Engel, Klaus; Kraus, Martin; Ertl, Thomas (The Eurographics Association, 2001)
    We introduce a novel texture-based volume rendering approach that achieves the image quality of the best post-shading approaches with far less slices. It is suitable for new flexible consumer graphics hardware and provides ...
