Joel" Subject: PROLOG and Graphics I am presently beginning doctoral research regarding the use of PROLOG for computer animation. What I would appreciate are any references you might have concerning the use of PROLOG (any version) to create computer graphics in general. I am specifically interested in PROLOG, but article relating to LISP or AI would also be of help. Thanks!

Assuming 8 bits each of red, green, blue, alpha (0 in a 24 bit buffer), should red be in the least significant bits? should blue? should alpha? should green? Cast your vote for RGBA, ABGR, ARGB, or another combination (where Z represents the least significant bits of WXYZ). Also, of course include your reasoning. Also please send info about how any commercial hardware or software keep data. Maybe we can develop some consensus to help everyone tired of shuffling bytes. A summary will be posted to the net. Thanks. -- Nick England, Sun Microsystems, Raleigh NC sun!nengland nengland@sun.com P.S.

The panel speakers will focus on computer graphic art careers and educational opportunities in the Bay Area. Areas of particular emphasis will include the broadcast/entertainment fields and desktop publishing. It will be held Sept. 22, 7:30 pm at the San Francisco Art Institute auditorium located at 800 Chestnut Street. Admission free. Come early, seating is limited. For more info, call (415) 321-5046. ------------------------------ From: jr@io.att.com (j.ratsaby) Subject: help for hardware designer Date: 15 Sep 87 20:50:43 GMT I need to know if there are any packages (PC oriented) that enable a user to enter timing diagrams (instead of sketching them on a graph paper) and thenany modification in one timing diagram will influence the edges and the transitions in all the other timing diagrams (sort of a graphics editor ). I really appreciate if anyone has any information on something like that please reply to me personally, thanks in advance joel ------------------------------ Date: 16-SEP-1987 16:32:36 GMT -01:00 From: THOWARD <@NSS.Cs.Ucl.AC.UK,@cs.ucl.ac.uk:THOWARD@graphics.computer-science.manchester.ac.uk> Subject: Tree-drawing algorithms I'm interested in the automatic (and good-looking!) display of the structure of directed graphs (and trees).

I'am sure there are good algorithms out there, since people like Apple show them off in the Mac II advertisements. Literature references or source code (shareware or payware) would be greatly appreciated. Thanks in advance.

Werkman (KJW1) NSF-ERC: ATLSS Project B1" Subject: No FTP, Posting a question [Manually forwarded by the moderator:] I would like to [ask] a question about SunGKS. We have version 2.0 and there seems to be problems in doing rubber-band locator input on the Sun. I was wondering if anyone else out there has noticed the adverse effect that we get when we try it....I.e. the System gets a bus error and reboots. Obviously a bug...I guess. Can anyone out there tell me how to get rubber-band locator input using SunGKS? (What is the correct FORTRAN data record for packing...) Thanks...

Input to the buffer from the serial port that the HPGL device is "supposed" to be attached to. When the graphics output is done, read from the spooler via the same or another serial port into a file. Or buy a second PC and feed its serial port directly, hopefully with X-ON/X-OFF flow control so nothing is lost when the second PC has to go dump its buffer to disk.
