SC 24

Revision 2012

ISO/IEC JTC 1/SC 24 Computer Graphics and Image Processing

Past JTC 1 activities (Resolution 21)

 

The origins of SC 24 are in the field of computer graphics.

In 1972, a Graphic Standards Planning Committee (GSPC) was established by ACM SIGGRAPH in the United States

In May 1976, the Seillac  I workshop was established under the auspices of IFIP WG 5.2. The Seillac I meeting marked the beginning of formal moves to achieve a set of standards for computer graphics by consensus among experts in the field. The activities generated by Seillac I developed into the efforts of ISO.

Until late 1987, computer graphics work took place in ISO/TC 97/SC 21/WG 2, where ISO/TC 97 was the technical committee that had the responsibility for Information Processing Standards. The first formal meeting of WG 2 was held in Bologna in September 1978. The work of WG 2 focused on the Graphical Kernel System (GKS) that had been developed within the DIN (German NB) group. (WG 2 may have later been moved to SC 5).

The work of WG 2 resulted in GKS being published as ISO 7942 on 15 August 1985. It was the first ISO standard to be published for computer graphics programming.

Present JTC 1 Activities of SC 24 (Resolution 20)

 

In November 1987, JTC 1 succeeded ISO/TC 97. From then on, all computer graphics standards were assigned to JTC 1/SC 24.

The previous ISO/TC 97/SC 21/WG 2 was assigned to SC 24, which was initially structured into five working groups;

WG 1: Architecture

WG 2: Application Programming Interfaces

WG 3: Metafiles and interfaces

WG 4: Language Bindings

WG 5: Validation, Testing and Registration

GKS addressed only 2D functionality. As technical work on GKS drew to a close, attention turned to the standardization of 3D graphics. Some experts wished to extend GKS to GKS-3D, while others wished to produce a new system, PHIGS (Programmer’s Hierarchical Interactive Graphical System). It was decided to proceed with both projects.

GKS-3D was published in 1988.

PHIGS was published in early 1989.

SC 24 was subsequently reorganized to reflect the changes in work load. WG 2 and WG 3 were merged to form WG 6 (Computer Graphics). WG 1 was disbanded since it had no projects and it was no longer felt there was a need for an architecture group. The Imaging Rapporteur Group was reformed as WG 7 (Image Processing), which also took on the scope of work covered by WG 5. It was decided that language bindings should be assigned to the same WG as the main document, hence WG 4 was disbanded.

In 1999, a new working group, WG 8, was formed to cover Environmental Data Representation and to take on the responsibility for the developing the SEDRIS set of standards. At present, JTC 1/SC 24 therefore consists of three working groups;

WG 6: Computer Graphics

WG 7: Image Processing

WG 8: Environmental Data Representation
