An Efficient Parallel Ray Tracing Scheme for Highly Parallel Architectures
(The Eurographics Association, 1990)
The production of realistic image generated by computer requires a huge amount of computation and a large memory capacity. The use of highly parallel com puters allows this process to be performed faster. Distributed ...
A Cellular Architecture for Ray Tracing
(The Eurographics Association, 1990)
"We propose in this paper a massively parallel machine dedicated to image synthesis by discrete ray tracing techniques. This machine is a four-stage pipeline, the last stage being a bidimensional cellular array with one ...
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 ...
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, ...
Issues and Directions for Graphics Hardware Accelerators
(The Eurographics Association, 1991)
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 ...
The Triangle Shading Engine
(The Eurographics Association, 1990)
This paper describes an algorithm implementing the Gouraud-shading of triangles and its realization in hardware. Different realizations using span shading hard ware are discussed. Their drawbacks lead to the concept of a ...
