AN APPROACH TO A CALCULATION-MINIMIZED HIDDEN LINE ALGORITHM
(The Eurographics Association, 1981)Hidden line algorithms based on picture primitives only cannot recognize the areas of a picture completely visible or invisible. By testing each primitive of these areas they produce an overhead of calculations. Moreover ... -
A HARDWARE APPROACH TO THE CORE SYSTEM OF ACM/SIGGRAPH
(The Eurographics Association, 1981)A new structure of the picture generation pipeline for a high-performance vector refresh graphic system is proposed. This pipeline consists of a graphic processor calculating the viewing transformations, a refresh buffer ... -
STATE OF THE ART IN COMPUTER GRAPHICS: A SIGGRAPH PERSPECTIVE
(The Eurographics Association, 1981) -
Graphics Standards - Where are we ?
(The Eurographics Association, 1981)An overview is given of the state of the standardization efforts of ISO/TC97/SC5/WG2, which currently concentrate on GKS. The standardization activities are illustrated by presenting a recently incorporated concept of ... -
A GKS IMPLEMENTATION FOR METEOROLOGICAL APPLICATIONS
(The Eurographics Association, 1981)In this paper we describe a GKS implementation made at ECMWF and we point out some problems encountered related to the definition of GKS 6.2 and to the necessity to adapt to the meteorogical applications. -
TIME AND SPACE BOUNDS FOR HIDDEN LINE AND HIDDEN SURFACE ALGORITHMS
(The Eurographics Association, 1981)Asymptotic worst case time bounds for three hidden line algorithms are derived and analysed. The first algorithm is a brute force solution that needs at least quadratic time. The second exact hidden line algorithm is based ... -
MOVIE.BYU - 1981
(The Eurographics Association, 1981)MOVIE.BYU facilitates the display of three-dimensional mathematical, topological, and architectural models as line drawings or as continuous tone shaded images. This software provides the capability to clip and cap three ... -
A Revolution in Hardware Systems Design and its Implications for the Graphics Community
(The Eurographics Association, 1981) -
THE IMPACT OF COMPUTER GRAPHICS ON INDUSTRIAL PRODUCT DEVELOPMENT
(The Eurographics Association, 1981) -
ABSTRACT DATA TYPE BASED PROGRAMMING STYLE AND COMPUTER GRAPHICS
(The Eurographics Association, 1981)The next generation of "intelligent" industrial robots will necessitate off-line programming systems in which generative graphics (picture generation) and cognitive graphics (picture understanding) is combined. This will ...
