Anti-Aliased Line Drawing on a Distributed Cell Store System
(The Eurographics Association, 1992)One of the principle drawbacks with traditional parallel image composition architectures is the lack of support for transparent images. This paper introduces the Distributed Cell Store System, an architecture based on image ... -
M-Buffer: A Flexible MISD Architecture for AdvancedGraphics
(The Eurographics Association, 1992)Contemporary graphics architectures are based on a hardware-supported geometric pipeline, a rasterizer, a z-buffer and two frame buffers. Additional pixel memory isused for alpha blending and for storing logical information. ... -
Hardware Challenges for Ray Tracing and Radiosity Algorithms
(The Eurographics Association, 1992)Computer graphics algorithms and graphics hardware have mainly been developed along two lines: real-time display and realistic display. Real-time display has been achieved by developing dedicated hardware for projective, ... -
A Parallel-Pipelined Multiprocessor System for the Radiosity Method
(The Eurographics Association, 1992)Ray-tracing and radiosity algorithms can produce very realistic images, but they require a lot of computations which make them impractical for scenes of highcomplexity. Several attempts have been made to speed up computations ... -
Distributed Frame Buffer for Rapid Dynamic Changes to 3D Scenes
(The Eurographics Association, 1992)This paper describes a distributed frame buffer architecture, based on the Tiling Algorithm for dynamic modification, and designed to achieve fast display updates inresponse to dynamic transformations of graphical objects. ... -
Parallelization and Hardware Support for Ray Tracing
(The Eurographics Association, 1992)Even on the latest workstations ray tracing is still a very time-consuming algorithm.This paper makes a thorough analysis of previous attempts to accelerate raytracing by means of parallelization with general purpose ... -
On the Design of a Real-Time Volume Rendering Engine
(The Eurographics Association, 1992)An architecture for a Real-Time Volume Rendering Engine is given capable of computing750x750x512 samples from a 3D dataset at a rate of 25 images per second.The RT-VRE uses for this purpose 64 dedicated rendering chips, ... -
An Extended Volume Visualization System for Arbitrary Parallel Projection
(The Eurographics Association, 1992)We present a special architecture for arbitrary parallel projection for visualization ofvolumetric data. Using a ray-casting technique, parallel memory access, and pipelinedprocessing of rays in a composition tree, we can ... -
Transputer-based Parallel Ray Tracing System Using Demand Data Transfer
(The Eurographics Association, 1992)This paper describes a parallel ray tracing system MAGG which has 86 transputers and HDTV frame buffers. Our system is based on a screen subdivision algorithm. In this algorithm, each processor essentially requires entire ... -

Accelerating Polygon Clipping
(The Eurographics Association, 1992)Polygon clipping is a central part of image generation and image visualization systems.In spite of its algorithmic simplicity it consumes a considerable amount of hardware or software resources. Polygon clipping performance ... -
Hardware Acceleration of Texture Mapping
(The Eurographics Association, 1992)We present a hardware design based around scan-line algorithms. The design can perform colour mapping, environment mapping and produce shading effects which include a specular term. We describe the algorithms which are ... -
ASICs for a High Performance IVIulti Processor Systemfor Photo-realistic Image Synthesis
(The Eurographics Association, 1992)A number of ASIC architectures are presented to build a system for fast photorealistic rendering of complex images. Both ray tracing and radiosity algorithms can be used. The system consists of a number of custom and general ... -
An Architecture for Interactive Raster Graphics
(The Eurographics Association, 1992)A radical reappraisal of the 3-D Interactive raster graphics pipeline has resulted In an experimentalarchitecture for a workstation which is currently being evaluated at the CWI. The principal features of thisarchitecture ... -
Testing Geometric Primitive Shaders
(The Eurographics Association, 1991)We present a design and test strategy for Geometric Primitive Shadersintegratedcircuits which perform rasterisation of primitives such as vectors and triangles.The design strategy proceeds through various levels of detail, ... -

Space Partitioning for Mapping RadiosityComputations onto a Pipelined Parallel Architecture (II)
(The Eurographics Association, 1991)A new space partitioning technique is elaborated. In part I of the paper [3], we proposed a shell-like structure which is to be superimposed on a uniform grid data structure and is adaptive to the local environment seen ... -
Accurate Scanconversion of Triangulated Surfaces
(The Eurographics Association, 1991)Scanconverting a planar face produces depth-values for pixels totally or partly covered by the projection of that face. State-of-the-art hardware-supported scanconversion techniques use sub pixel adjustment and extended ... -
The Flipping Cube: A Device for Rotating 3D Rasters
