    • Adaptive Hierarchical Visibility in a Tiled Architecture 

      Xie, Feng; Shantz, Michael (The Eurographics Association, 1999)
      This paper describes a method for occlusion culling in a tiled 3D graphics hardware architecture. Adaptive hierarchical visibility (AHV) is a simplified method for occlusion culling that is integrated into a tiled architecture ...

    • Antialiased Parameterized Solid Texturing Simplified for Consumer- Level Hardware Implementation 

      Hart, John C.; Carr, Nate; Karneya, Masaki; Tibbitts, Stephen A.; Coleman, Terrance J. (The Eurographics Association, 1999)
      Procedural solid texturing was introduced fourteen years ago, but has yet to find its way into consumer level graphics hardware for teal-time operation. To this end, a new model is introduced that yields a parameterized ...

    • Hybrid Volume and Polygon Rendering with Cube Hardware 

      Kreeger, Kevin; Kaufman, Arie (The Eurographics Association, 1999)
      We present two methods which connect today s polygon graphics hardware accelerators to Cube-5 volume rendering hardware, the successor to Cube4 The proposed methods allow mixing of both opaque and translucent polygons with ...

    • 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 ...

    • 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 ...

    • 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)
      The creation of high-quality images requires new functionality and higher performance in real-time graphics architectures. In terms of functionality, texture mapping has become an integral component of graphics systems, ...

    • Texture Shaders 

      McCool, Michael D.; Heidrich, Wolfgang (The Eurographics Association, 1999)
      Extensions to the texture-mapping support of the abstract graphics hardware pipeline and the OpenGL API are proposed to better support programmable shading, with a unified interface, on a variety of future graphics accelerator ...

    • TRIANGLECASTER Extensions To 3BTexturing Units For Accelerated Volume Rendering 

      Knittel, Gunter (The Eurographics Association, 1999)
      We discuss hardware extensions to 3D-texturing units, which are very small but nevertheless remove some substantial performance limits typically found when using a 3D-texturing unit for volume rendering. The underlying ...

    • Z3: An Economical Hardware Technique for High-Quality Antialiasing and Transparency 

      Jouppi, Norman P.; Chang, Chun-Fa (The Eurographics Association, 1999)
      In this paper we present an algorithm for low-cost hardware antialiasing and transparency. This technique keeps a central Z value along with compact floating-point Z gradients in the X and Y dimensions for each fragment ...
