- These are standards documents and can be obtained from the standards
- bodies (ANSI - American National Standards Institute/ISO -
- International Organization for Standardization) as well as some third party
- sources. The FAQ mentioned one source for PHIGS standards documents;
- I've included that section below. As for the PHIGS-PLUS standard,
- there is a more recent version than the 20 March 1990 version. I have
- in my manual:
-
- ISO/IEC 9592-4:199x Draft International Standard, 14 February 1991
-
- I'm not sure if this vote has been taken to move the specification
- from DIS into a fully-approved standard. The preface on my copy says:
-
- ``ISO (the International Organization for Standardization) is a
- worldwide federation of national standards bodies. The work of
- ppreparing International Standards is normally carried out through
- ISO technical committees. Every member body interested in a
- subject for which a technical committee has been established has
- the right to be represented on that committee. International
- organizations, governmental and non-governmental, in liasison with
- ISO, also take part in the work.
-
- Draft International Standards adopted by the technical committees
- are circulated to the member bodies for approval before their
- acceptance as International Standards by the ISO Council. They
- are approved in accordance with ISO procedures requiring at least
- 75% approval by the member bodies voting.
-
- The document editor for this Standard was Tom Gaskins, whose work
- was funded by Sun Microsystems Inc.''

- GKS - Graphical Kernal System - geometric graphics system
- CGM - Computer Graphics Metafile - archive of graphics commands - very

- PHIGS - the best graphics standard! 3D geometric graphics with lighting

- I know I've seen other overviews of graphics standards. Just none recently.
-
- There are a couple of books on CGM and GKS, but I do not have the
- references written down.
-
- As, for PHIGS, you can get the standard itself from ANSI in New York.
- (212) 354-3300. [The following table gives the ANSI standard numbers
- corresponding to the PHIGS standards:
-
- ANSI X3.144-1988 ISO 9592 parts 1, 2 and 3 for PHIGS
- ANSI X3.144.1 ISO 9593-1 for PHIGS FORTAN binding
- ANSI X3.144.3 ISO 9593-3 for PHIGS Ada binding
- ANSI X3.144.4 ISO 9593-4 for PHIGS C binding
-
- --RT] They will also have the GKS and CGM specs.
