GPLOT: THE CGM INTERPRETER
Hello Folks:
In the last few weeks I have seen several posts to this BBoard
regarding Computer Graphics Metafiles (CGM) and software for
interpreting CGM files.
At the Pittsburgh Supercomputing Center, we have a program called
"GPLOT" which reads a CGM file, and displays it on different devices.
Gplot can create (color) postscript files from CGM files as well.
The original Gplot software was written in C, runs on both VMS and
UNIX systems, and has quite a few device drivers (Tektronix, Postscript,
Sunview, Decwindows, X windows, IRIS GL, and more).
GPLOT is being re-written completely in C++. It is still under development,
and is not fully debugged. The first version was released in April 1991.
Binaries are available for Decstations and Macintoshes at the moment.
We plan to have binaries for the Suns, the IBM RS6000 systems as soon
as possible. X11R4, and Motif 1.1 or later, and a C++ compiler are required
to build the C++ Gplot. The most impressive feature of the new Gplot is
that it allows you to view animations on the workstation or the Macintosh.
GPLOT is freely available, but it is copyrighted.
GPLOT is available via anonymous ftp from calpe.psc.edu (128.182.62.148).
ftp in as user anonymous (any password).
(1) To get the C GPlot software, cd to pub/gplot, and get the file
gplot.tar. Un-tar it on your system and use the Makefile to build
it. For VMS systems, a COM file and a MMS file are available.
The README file and the gplot.txt file has more information.
(2) To get the C++ Gplot binaries for the Decstations:
cd to pub/gplotc++/bin, and get the file gplotm.decstation.
If you have the C++ compiler and X11R4, Motif 1.1 or later
available on other systems, get the gplotc++.tar file from
pub/gplotc++, and try compiling the software on that system.
(3) Three binary versions of MacGplot, "macgplot", macgplotmacII and
"macgplotfpumacII", are available. "macgplot" runs on any Macintosh
running System 6 with Color Quickdraw routines. "macgplotmacII"
requires a Macintosh II with or without a floating point co-processor
(FPU). "macgplotfpumacII" runs on a Macintosh II with FPU. The
binaries are stored in two formats, "macbinary" and "binhex4.0".
All the MacGPlot binaries are stored in pub/macgplot/bin.
To get the binary "macgplotfpumacII.bin", cd to pub/macgplot/bin,
and transfer the binary in "macbinary mode". This should get APPL
"macGPlot FPU macII".
(4) Sample CGM files are located in pub/cgm. Get the file jet.cgmb
for animating (transfer in binary mode).
Please let me know if you have any problems using Gplot, and send
"Wow, it works!" messages, and bug reports if there are any.
Also, send me mail as soon as you pick up a copy of Gplot, so I can
add you to our mailing list for future releases of Gplot.
