Subject: please help: bitpads and Sun SPARCstation
Keywords: bitpad driver Sun SPARC
Organization: National Inst. of Health, DCRT, CSL
Date: Tue, 12 Jan 1993 15:59:22 GMT



Our lab is using a Sun SPARCstation for much of our image-processing
and we would like to use a bitpad (aka "digitizing pad") and stylus
("pen") instead of a mouse to draw our regions of interest.

There are several bitpads which can attach to the Sun SPARCstation,
including the Microgrid III and the SummaSketch II Plus by
Summagraphics, but we have not been able to find *any* software to
drive any bitpad for a SPARCstation.  Does anyone out there know of
any bitpad drivers for SPARCstations?

Please send any information to joem@alw.nih.gov or diane@alw.nih.gov.
Or call (301) 402-1737, and ask for Joe or Diane.  We would very much
appreciate any help.

Well, yes, this is a good point.  Except that we are talking about
electronic publishing.  A major advantage of non-print media is that
the *original* images (i.e. scientific results) can be distributed,
*without printing artifacts*.  If this undergoes lossy compression,
it has the same degradation problems as, say, print pubilcation.

To some degree this is true.  You must also remember the stated
purpose of JPEG -- its lossy compression results are nearly
indistinguishable from the originals, which happen to be digitized
natural scenes.  That means lots of small detail, photographic grain
and other defects of the process, etc.  Computer generated images,
being a computational product, are much cleaner.  CGI is simply not
what JPEG is optimized for, and I bet I could tell the difference
between an original and a 2 bit per pixel lossy compression of most
computer generated images.

I'm am looking for (PD or cheap) programs for visualization of bio

about it? Only pgms I could find cost usually about US$10,000.

I prefer Unix (Sun 10), but Mac, PC or even NeXT would work too.

     image processing (esp. fractals)
     space, aeronautics
     weather forecasting
     physics (esp. lasers)
     signal processing
     information theory

Please e-mail your responses (short or long!) directly to me 
(gmmiller@mcs.drexel.edu).  The survey is for my own use (academic and

And for those of us who have need for the Image Tools and are running on an
unsupported machine  ---  and realize that government money has gone into
developing this inaccessable software:

Consider writing the NSF and your congressperson.  Policy decisions about
release of work developed at the supercomputer centers needs to be set where
the bills are paid, not at a local level.  Mention the new HPCC Program
proposed to Congress.  Personally, I'm going to contact 
some personal friends within the government and call their attention to the
source code availablility issue, without pointing to any specific problem with
SDSC.

The intent and benefit of the Federal High Performance Computing and
Communications (HPCC) Program "is to accelerate significantly the availability
and utilization of the next generation of high performance computers and
networks in a manner consistent with the Strategic and Integrating Priorites
..."  And " ... HPCC will emphasize the integration of multiple tools developed
by different organizations for use on multiple hardware platforms." ...
"Library efforts will lead to a software interchange capability that can
support exchange of software components among researchers, enabling
collaborative development of systems through appropriate sharing of software
assets." 

If I review the SDSC posture re: source distribution, it is difficult to see
just how it meets the goals of the new HPCC Program.  SDSC may have good
reasons for their present posture, but I suggest they seriously consider
reviewing that posture.

		Summer Workshop for Faculty
	   High-Performance Scientific Computing 
         University of Colorado, June 7 - 18, 1993

This residential workshop is designed for college faculty 
members interested in teaching scientific computing to 
undergraduate students. Its objectives are to present 
an early draft of course material we have developed to 
potential instructors, to critique it, and to
discuss ways of incorporating it into a college curriculum.
This material was developed for an undergraduate course in 
"High-Performance Scientific Computing" under a grant from the 
National Science Foundation.

Students in our course learn to use high-performance 
workstations and supercomputers through laboratory exercises 
representative of scientific applications.
The exercises include numerical computation, scientific visualization,
and performance measurement. Our laboratory is equipped with 
DEC 5000 and SGI Indigo workstations and Xterminals; we access
supercomputers over a network.

Approximately 60% of the workshop time will be devoted to
laboratory sessions. The remainder will be devoted to tutorials on
the course material and to discussions of 
how to teach this subject to undergraduates, including
practical matters of hardware and software
requirements, teaching methodology, and breadth and depth of the
subject matter.

Participants will reside in Crosman Residence Hall on the campus.
Classes and laboratory sessions will be held in the Engineering Center
located nearby. Residence expenses (room and board) will be paid by
a grant from the National Science Foundation. Transportation expenses will
not be covered.

Attendance will be limited to sixteen participants, selected according to
these criteria:

	Statement of interest. This statement describes the applicant's 
	interest in participating in this workshop and relevant academic 
	experience.

	Satisfying the prerequisites. The prerequisites are experience with 
	the Unix operating system and C or Fortran, 
	knowledge of undergraduate numerical analysis.

Faculty members from four-year colleges are especially encouraged to apply.

Some course materials are available by anonymous FTP from cs.colorado.edu
in directory /pub/cs/HPSC.

Inquiries and applications should be sent to: Professor Elizabeth Jessup,

[ Followed by a couple hundred lines of hand-wringing about the difficulties
of supporting source code releases. ]

Yup, it's not trivial; but if you pick a decent methodology, lay down
the ground rules early (such as: "We don't support your broken fix to
someone else's broken enhancement") and utilize reasonable source code
control mechanisms (RCS, CVS, et.al.) it can be done with a minimum
of headaches.  If you need assistance with this process, I'd suggest
contacting the Khoros, GNU, or X11 folks, all of whom support *huge*
software packages in a highly commendable fashion.  You might also want
to ask them how they feel about all the help they've had from the network
community, precisely because they released their source code.

If, after that, you still just want to send a binary release, fine; just
don't expect all of us to get excited about it, use it, or contribute to it.

We are doing pretty much just what you are.  Instead of airplane track, we are
showing wind vectors and colored objects which represent monitored pollutants.

We are running AVS on a Kubota Pacific Titan.  Data is pre-processed on a
Macintosh Quadra and standard AVS modules do all the visualization.  We
had to "cook" the terrain map, as it is not rectangular in the region of
the earth we're dealing with.

Should you decide to go this route, I can provide you with some hints and
tricks.

Subject: RFI: auto creation of raster files from variable segments
Organization: Cal State Long Beach
Distribution: usa
Date: Mon, 11 Jan 1993 19:22:01 GMT

I have a graphical problem and am looking for a solution.

Brief statement of problem:

I need to take the output of a user display prgram running
under X and make it available for display in an propriatary
X-based presentation program (kind of like a Freeland for X).

This would be easy if I could use xwd to dump the screen,
convert the dump to GIF, crop the gif file, an import the
GIF file into the presentation system (as a "slide").

The problem is this problem has to be automatic: It has to
happen in the backgroup. The user program may not even be
up and running at the time and the specific screen is 
nested within another program.

The original display is made of colored icons, fonts and cells and
is driven from d fixed-length, but variable data, text file.

Potential solutions?

I have access to the same data file information. 

One way I guess
would be to create a composite graphical file using a programable
vector language like postscript based on the variable data, and
import the result as an EPS file or convert to a raster file.

Another would be to have a bunch of raster "segments" or icons that could
somehow be concatinated to form a single composit raster file
(GIF, TIF, etc.). But, this has to be done programatically.

Any suggestions or pointers (programs on the net, code fragments, etc.)?
