      Kugler, Anders (The Eurographics Association, 1998)
      Data path simplification in the context of reflection- and bumpmapping hardware opens new solutions in the design of rendering and shading circuits. We are proposing a novel approach to rendering bump- and reflection-mapped ...

    • A Low-Cost Memory Architecture For PCI-Based Interactive Ray Casting 

      Doggett, Michael; Meißner, Michael; Kanust, Urs (The Eurographics Association, 1999)
      In this paper we present a low-cost memory architecture running at 100 MHz which is suited for any PCI-based volume rendering accelerator using the ray-casting approach. Current SDRAM technology, parallel access to all ...

    • Memory Access Patterns of Occlusion-Compatible 3D Image Warping 

      Murk, William R.; Bishop, Gary (The Eurographics Association, 1997)
      McMillan and Bishop s 3D image warp can be efficiently implemented by exploiting the coherency of its memory accesses. We analyze this coherency, and present algorithms that take advantage of it. These algorithms traverse ...

    • Multiresolution Rendering With Displacement Mapping 

      Gumhold, Stefan; Hüttner, Tobias (The Eurographics Association, 1999)
      In this paper, we present for the first time an approach for hardware accelerated displacement mapping. The displaced surface is generated from a 2D displacement map by remeshing a coarse triangle mesh according to the ...

    • Neon: A Single-Chip 3D Workstation Graphics Accelerator 

      McCormack, Joel; McNamara, Robert; Gianos, Christopher; Seiler, Larry; Jouppi, Norman P.; Correll, Ken (The Eurographics Association, 1998)
      High-performance 3D graphics accelerators traditionally require multiple chips on multiple boards, including geometry, rasterizing, pixel processing, and texture mapping chips. These designs are often scalable: they can ...

    • Optimal Depth Buffer for Low-Cost Graphics Hardware 

      Lapidous, Eugene; Jiao, Guofang (The Eurographics Association, 1999)
      3D applications using hardware depth buffers for visibility testing are confronted with multiple choices of buffer types, sizes and formats. Some of the options are not exposed through 3D API or may be used by the driver ...

    • Parallel Texture Caching 

      lgehy, Homan; Eldridge, Matthew; Hanrahan, Pat (The Eurographics Association, 1999)
