Could someone please tell me where I can get PHIGS and PEX and whether they are commercial products or public domain. Any references would be appreciated. Thanks, Leonid. frants@neon.stanford.edu

PHIGS is available from all workstation vendors. Call your sales rep. PEX was demonstrated in 6 booths at SIGGRAPH this year: DEC, Sun, Alliant, Tektronix, E&S and IBM. Only DEC and E&S claimed it was a product; the rest were "technology demos". PEX is the PHIGS Extension to X11 and will be available from MIT next summer - summer 1991, I believe it will be available in the same time frame as the R5 distribution. As for references, there are not too many good ones yet. There is the source of both PEX & PHIGS - the defining specifications. PEX: I think all of the X distributions have had the contemporary PEX protocol specifications with them. In R4 you can find it in ..x11r4/mit/doc/extensions/PEX/*.ms And PHIGS88: Computer Graphics-Programmer's Hierarchical Interactive Graphics System (PHIGS) Functional Description... ANSI Standard X3.144-1988. (Language bindings are X3.144.x, where x=1 (FORTRAN), 2 (PASCAL), 3 (ADA), 4 (C).) Call ANSI in New York for ordering (212)354-3300 And PHIGS-PLUS since it is not a standard you can get the latest public review copy from Global Engineering (800)854-7179 At SIGGRAPH I asked all of the publishers there if they had and books on PHIGS. Only Addison Wesley and Prentice Hall knew what I was talking about. They both have books in the works, both due out early next year, at least, accoding to people in thier booths at SIGGRAPH. I also heard Template is going to update thier book "Understanding PHIGS". Also, here are some tidbits about PHIGS ( or SPHIGS ) in the new Foley, van Dam, Feiner & Hughes. >>> Subject: PHIGS in Foley, van Dam, Feiner and Hughes. Message-ID: <1990Jul18.192939.2473@Stardent.COM> Date: Wed, 18 Jul 90 19:29:39 GMT Foley, van Dam, Feiner & Hughes have a chapter on SPHIGS ( Simple PHIGS (where PHIGS = PHIGS88 + PHIGS-PLUS + ?? )) which is loosely based on the standard. For example, it has no bundles and no UQUM or Use Quick Update Methods or Yookum. It does have things like posting to views and programmatic picking. Lighting and shading are there. While this may not be much of a practical introduction to standard PHIGS, it does give the concepts pretty well. And at 60 pages, it is probably the quickest way to start shooting buzzwords like a "real PHIGS expert". The most interesting thing about SPHIGS is that you can order source code for it. The introduction states that source code for SPHIGS, SRGP and other algorithms running on the IBM-PC, the Mac or UNIX/X11 may be purchased from the publisher, Addison-Wesley.

Send email to graphtext@cs.brown.edu and place "Software-Distribution" in the subject line. -- -Jan "YON" Hardenbergh - jch@stardent.com uunet!stardent!jch Stardent Computer, Inc., 95 Wells Ave., Newton, MA 02159 (617)964-6228x261

In my book Wisskirchen: Object-Oriented Graphics - From GKS and PHIGS to Object-Oriented Systems - (August 1990, 236 pp. $ 39.00) I tried to compare OO with traditional approaches (ISBN 3-540-52859-8 Springer Berlin ... ISBN 0-387-52859-8 Springer New York ..) A lot of material is devoted to PHIGS, showing mainly its weak points if you analyze it from an object-oriented view. But at present, no elegant alternative is available on the market (as far as I know). (In the international standard committees, a new graphics standard is discussed under the key word "NewAPI" with a strong tendency towards an object-oriented standard of the ninetees. Specialists with experience in graphics and oo programing are needed to contribute to this developement. ) Contents of the book: Guidelines for Designing Graphics Systems. - Object-Oriented Programming in Smalltalk-80. - User Interface Architecture: Application Frameworks, MVC Concept. - Smalltalk-80 Graphics Kernel. - GKS, PHIGS and Object-Oriented System Design. - Generation and Editing of Multi-Level Part Hierarchies. - Programming Examples. - Extension of a Graphics Kernel by Use of Inheritance. - Attaching Additional Semantics. - How to Integrate Constraints. - Graphics and Knowledge Representation. - Prototypes and Delegation. - Requirements for an Object-Oriented Graphics Standard. Book's subject matter: This book builds up a synthesis between the functionality of traditional graphics systems, such as the international standards GKS and PHIGS, and the potential of object-oriented systems. Based on concrete examples it shows the conceptual progress which can be reached by object-oriented design philosophy and the use of object-oriented tools for computer graphics.
