Has anyone ported the University of Illinois PEX implementation uipex to a Sparc Station. If not I will attempt this myself but don't wish to do this if the problem has already been solved. James R Logie University Of Glasgow Scotland

I got the server working with the MIT X distribution, but the colormaps weren't right when I ran the demos. I suspect they made some platform-dependant assumptions about colormaps, but I couldn't take the time to track it down. I made some substantial changes to some of the code to get it to work. If you'd like, I could send you a diff file with the changes.

A word to the wise, if you are planning to invest lots of time and energy into a PEX server, you should become a member of the MIT X consortium and get the Beta version of the X11R5 release (available sometime soon). The PEX-SI (sample implementation) is scheduled to be on it. This implies the the PEX-SI will be part of the public release of X11R5, but that won't be available in the near term - those consortium people like to keep thier word and so they use weather prediciton analogies to specify thier release dates - something about it getting cold again. I have not looked at the guts of UIPEX, but it is based on either PEX version 3.2 or 4.0. It will not be interoperable with the first large crop of PEX products - based on PEX 5.0P. Since UIPEX was used as the basis for at least Kelvin Sung's thesis, it has pretty good documentation, as does the PEX-SI. The PEX-SI has great user man pages. I do not want to discourage anyone from porting UIPEX as a great way to get some 3D graphics into X. It's here now and seems to have been done well. I just want to warn people considering big investments that they should join the X consortium and get the Beta for X11R5 - or if possible, just wait until X11R5 goes public. -- -Jan "YON" Hardenbergh jch@stardent.com (508)-371-9810x261 Stardent Computer, 6 N.E.

Also, I believe it has a home-brew C binding and not a binding that tracks the ANSI proposed C binding for PHIGS/PHIGS-PLUS. -- Rich -- ``Read my MIPs -- no new VAXes!!'' --George Bush after sniffing freon Rich Thomson thomson@asylum.utah.edu
