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
      useful for plotting.
PHIGS - the best graphics standard!  3D geometric graphics with lighting
      and shading and neat primitives to draw fancy pictures.
If you are looking for a broad overview of graphics standards you might

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.
