Some Possible Applications of CORDIC Processors in Computer Graphics
(Eurographics Association, 1990)
Some application possibilities of an ASIC-type processing element, the CORDIC processor, in computer graphics are discussed. CORDIC-based solutions are derived for some basic computer geometry computations: conversion ...
Shading and Shadowing with Linear Light Sources
(Eurographics Association, 1990)
In virtually all rendering systems, linear light sources are modeled with a series of point light sources that require considerable computing resources to produce realistic looking results. A general solution for shading ...
Tightly-Coupled Multiprocessing for a Global Illumination Algorithm
(Eurographics Association, 1990)
A prevailing trend in computer graphics is the demand for increasingly realistic global illumination models and algorithms. Despite the fact that the computational power of uniprocessors is increasing, it is clear that ...
A Constraint-Based Figure-Maker
(Eurographics Association, 1990)
In this paper, we describe a new kind of constraint-based figure-maker for parametrically defined curves. Figures are made by defining objects and imposing constraints on their geometric behavior. We present a formulation ...
INTERACTIVE RAY-TRACING FOR IMAGE PRODUCTION WITH INCREASING REALISM
(Eurographics Association, 1990)
The generation of highly realistic images using the conventional Ray-Tracing algorithm, in CAD environments, is totally out of the question if we consider the interactive requirements of most CAD systems. In this paper, ...
HYPERIMAGES - AN ALTERNATIVE TO THE CONVENTIONAL DIGITAL IMAGES
(Eurographics Association, 1990)
Hyperimages represent a variation of the conventional digital images which implies pixels of different dimensions within the same image. The extent of a hyperimage is the disjoint union of all pixel extents it contains, ...
RECONSTRUCTION OF A BOUNDARY REPRESENTATION MODEL FROM THREE ORTHOGRAPHIC PROJECTIONS: A GEOMETRICAL APPROACH
(Eurographics Association, 1990)
A method is presented for creating a boundary representation model from engineering projections. Although the topic of this reconstruction method has been studied for a few years the fundamentals of reconstruction are ...
Factoring a Homogeneous Transformation for a more Efficient Graphics Pipeline
(Eurographics Association, 1990)
We identify an intermediate coordinate system situated between world coordinates and display coordinates, which exhibits unique features for lighting calculations and for clipping in homogeneous coordinates. Our key ...
THREE-DIMENSIONAL TEXTURING USING LATTICES
(Eurographics Association, 1990)
This paper describes a way to perform realistic three-dimensional texturing of ray-traced objects with irregular surfaces. Such texturing has teen done in the past with texture mapping, particle systems, or volumetric ...
CHARACTERIZATION OF TOPOGRAPHIC SURFACES
(Eurographics Association, 1990)
This paper presents a method for extracting and representang features of a topographic surface approximated by triangular tales An algorithm as given which computes characteristic regions (a. e. regions having concave, ...
