- Graphical Kernel System
The Graphical Kernel System (GKS) was the first ISO standard for low-level
computer graphics, introduced in 1977. GKS provides a set of drawing features for two-dimensional vector graphicssuitable for charting and similar duties. The calls are designed to be portable across different programming languages, graphics devices and hardware, so that applications written to use GKS will be readily portable to many platforms and devices.
GKS was fairly common on
computer workstations in the 1980s and early 1990s, and formed the basis of Digital Research's GSX and GEM products; the latter was common on the Atari STand was occasionally seen on PCs particularly in conjunction with Ventura Publisher. It was little used outside these markets and is essentially obsolete today except insofar as it is the underlying APIdefining the Computer Graphics Metafile. A notable descendant of GKS was PHIGS.
A main developer and promoter of the GKS was
Professor José Luis Encarnação, formerly director of the Fraunhofer Institutefor Computer Graphics (IGD) in Darmstadt, Germany.
ANSIstandard ANSI X3.124 and ISO standard ISO/IEC 7942. The language bindings are ISO standard ISO 8651. GKS-3D (Graphical Kernel System for Three Dimensions) functional definition is ISO standard ISO 8805 and the C bindings are ISO 8806.
