CUBICORT: A Hardware Simulation of a Multicolumn Model for 3D Image Analysis, Understanding and Compression for Digital TV, HDTV and Multimedia
(The Eurographics Association, 1993)We describe here simulation elements and results of a new kind of 3D Vision Machine. for pre-processing in 3D Object & movement analysis using the biological concept of the Cortical Column Paradigm in the primary visual ... -
An Architecture for Ray - Bezier Patch Intersection
(The Eurographics Association, 1993)A new fast ray - patch intersection algorithm is presented. The algorithm correctly handles all ray - patch intersections. A number of parametersare derived from a numerical analysis of the algorithm and the datapad is re ... -
A VLSI Design for Fast Vector Normalization
(The Eurographics Association, 1993)The design of a vector normalizer is described. It is an integral part of our graphics subsystemfor scientific visualization, but will be of great use for speeding up any computer graphics architecture.In the actual design, ... -
Parallel Fixed Point Digital Differential Analyzer
(The Eurographics Association, 1993)Two main serial algorithms to scan convert straight lines have beenproposed: Bresenham and Digital Differential AnalyzeLThe Bresenham algorithm has became a standard because of integer arithmetic. Many theoretical solutions ... -
Designing a half toning coprocessor
(The Eurographics Association, 1993)Halftoning is a fairly slow process when executedby software on conventional processors. To speed uphalf toning, a half toning algorithm has been developed andintegrated into a dedicated hardware architecture. Thispaper ... -
A Difference Engine for Image Reconstruction
(The Eurographics Association, 1993)A diffetence engine is described that is designed to be used as low level component of a raster graphicsarchitecture. The speed of the system (11 ns per operation) is achieved by the use of custom VLSI componentsfor the ... -
Real-Time Architecture for High Resolution Volume Visualization
(The Eurographics Association, 1993)This paper describes a high-performance &pecial-purpose system, the Cube-3 machine, fordisplaying and manipulating high-resolution volumetric datasets in real-time. Cube-3 will allowscientists, engineers, and biomedical ... -
Hemispherical Projection for Progressive Radiosity Calculation on Massively Parallel Architectures
(The Eurographics Association, 1993)This paper describes a massively parallel implementation of the progressive radiosityalgorithm. Our algorithm is based on an hemispherical projection approach, which provides an accurate from factor approximation. As the ... -
The Role of Power Dissipation and Locality of Reference in the Specification of High Performance Graphics Algorithms
(The Eurographics Association, 1993)The amount of power dissipated by the implementation of an algorithm, for instance in the form of a dedicatedchip-set, is considered to be one of the most important constraints for the selection of a high performance ... -
Direct Visualization of Quadrics
(The Eurographics Association, 1993)Today, most of the powerful graphic systems are based on 3D-triangle display methods.However, this approach generates well-known problems, like the low quality ofcontours and shading, and the necessity to have large amounts ... -
A Parallel Accelerator for Generating Virtual Studio Sets
(The Eurographics Association, 1993)Recent developments in digital video techniques and the use of computers in video andtelevision production provide new opportunities for programmes. Key technologies which embrace these developments are advanced computer ... -
VHDL Based Design of Graphics ASICs
(The Eurographics Association, 1993)The design of graphics ASICs for geometry and rasterisation processing has traditionally involved the use of schematic design entry where by functional blocks are netlisted and instantiatedon the schematic. This methodology ...
