The past several years the main SIGGRAPH conference has published course
notes on the subject.  Contact them for copies.  Their contact information
is in the journal "Computer Graphics" and is frequently posted in this
newsgroup.

As with any computer-oriented subject there are at least two ways of looking
at a subject.  There is the "techie" and "user" points of view.  The techie
point of view would concern the mathematics and programming algorithms to
implement scientific visualization.  This body of knowledge is fairly large
and would take several semesters to cover adequately IMHO.  And for the
most part, it is not too useful for users, except to discuss limitations of
method, e.g. slow speed, distorts results, etc.  Much of the SIGGRAPH material
and newly appearing textbooks show the techie side.  (I am a techie and love
reverse engineering any new piece of software or hardware.)

Turn-key, off-the-shelf visualization systems such as AVS are intricate
enough that one could spend a semester teaching proper use.  AVS now has
some 800 modules, though maybe a few dozen are commonly used.
Some things to explore are the correct presentation technique for each type
of data- are the data discrete continuous, linear, multidimensional, etc.?
-the needs of different sciences. 

I'd borrow material from traditional
graphics design courses.  Scientists can be unimaginative in their display.
For example, volume visualizations from widely different discplines appear
the same.  Other scientists display their results too elaborately and confusing.
Tufte's books on abuses of 1-D and 2-D ink graphics have their extensions
in scientific visualization.

Also important is an understanding scientific data analysis.  We scientists
don't want pretty pictures, but insight.  We want to see the flaws and holes
in our data.  May years ago, we gave an earth science dataset ta supercomputer
center scivi lab.  Their renderings kept on erasing the geological faults
that we wanted to see.  This was according to the default settings of their
software, a fault was a "blemish" in the data to be smoothed over.

i can't help you. but i can say thta you should take a look at the book

Due to the great interest, here is what I've found out:

There is a converter for HP/GL to CalComp (the plotter language)
by CalComp itself running on PCs.

Thanks to Andreas.Tranquillini@uibk.ac.at for that hint.

I don't have that program yet, so I can't say anything about it.


Futhermore there seems to be NO filter for PostScript to CalComp.



Thanks to all who answered,

Probably not (depends on your definition of "normal").  I'm not
familiar with Microtek, but "slide" scanners capture light that has
passed *through* the slide, NOT bounced off it.

I have a demo disk of IMAGE-IN for windows. While it does'nt have the save
feature, It is a very impressive commercial package. It reads gif, pcx, tiff,
tga and does have built in image inhancement of many kinds and a GIF to RGB
convertor. Very few tools are supported in the GIF mode but when RGB file
is loaded then all tools are available. Works very well in 8-bit, 16-bit and
24-bit modes. Don't know the cost or where to get it but I will find out if
you are interested. I have no afilliation with this product other than trying
their demo. The demo is on one 1.44meg floppy.

    I am writing a program with uses 640x480x256 graphics in the Borland C
enviroment.  I draw a figure in the main procedure and then I call a child
process with the execlp command.  I need to draw on the screen within the

to initialize the graphics with initgraph.  Unfortunately, when I use 
initgraph in the child process the screen the main program drew is erased
completely.  
    I am also having a problem reading the palette colors in 640x480x256 mode
I need to have a way to save the screen I drew and I can't seem to get the
RGB values of the 256 palette entries.  
    One last problem while I am at it.  I need to find out if the .BGI driver
I am using is copyrighted, protected, share-ware, public domain, etc.  And
if I need permission to use it, where do I get it from?  
    On a related subject... how do I change the .BGI to .OBJ so I can

That is an extremely interesting article! I look forward to trying to
obtain the translated texts and in sharing them with my son (13 years).
Further it would be interesting to obtain the Nihongo texts to assist
in out study of the language.

Certainly there are major deficiencies in the US (and in Europe to a
lesser extent) educational system. Certainly Japan has an incredible
educational system , with much to admire and to copy. One might reflect
however on the human cost of that system and wonder whether any European
derived society would be willing to pay that cost. Reflect on the suicide
rate amoung school children, the level of physical discipline , the bullying
and discrimmination that is taught and enforced in the absence of tracking.

There are other unsavory aspects that I do not wish to mention here because
I do not wish to be involved in flame wars.

We in the "west" should copy much of the educational aspects of the 
Japanese schooling , but we should not lose track of the fact that
ordinary Japanese teaching and discipline would get the teacher jailed
in many nations. Sweden , Denmark , and the US come to mind. 

The US could use the early schooling in some of the European countries
better if they are looking for a model that they would be willing to
actually make use of.

Would there be information available indicating what Japanese
computer firms are currently doing regarding RAID research
(especially RAID 7 and higher levels)?  If so, would Fujitsu, Hitachi,
or Toshiba be among the leaders?  How might such research match up with
recent work in the US?  Are they investing much money in this
technology, or is all going into HDTV? :-)   Any thoughts or ideas would
be very much appreciated!

-------------------------------------------

Regarding John Scoggin's request for information on RAID systems for
VINES, Storage Computer of Nashua, N.H. is currently showing its new high
performance RAID 7 disk array platforms at the September Banyan Users
Meeting.  They work equally well with NetWare, IBM systems, workstations,
the VAX, etc.

Standards-based, RAID 7 is designed for enterprise-wide computing and
overcomes performance limitations of earlier RAID architectures, providing
a  "real world sustained application performance improvement of 200% to
400%" and dropping the cost of storage to 16 cents/MB.  Their brochures
say they can "mix and match" up to 48 SCSI commodity (3.5 or 5.25 inch)
drives, up to 150 GB.  The RAID 7 disk array platforms come with an embedded
operating system and up to 12 SCSI-2 based host interfaces.  Besides servers,
Storage Computer's RAID 7 disk array platforms can connect to workstations
and midrange systems in addition to IBM's.  Multiple CPUs can be attached to
same disk array platform.

The RAID 7 platforms come with up to 256 MB of cache, eliminating any
reason for using performance-damaging CPU main memory disk RAM.

The drives are "hot plugable" for uninterrupted, transparent operation,
with a hot standby drive automatically replacing a failed drive.

There was a lot of activity yesterday at the Storage Computer RAID 7 booth
at the Banyan show as I walked by.  They were demoing what happens if a
drive goes down, showing the backup drive taking over.

For further information on Storage Computer's RAID 7 for the VAX, their
key contact is indicated to be John O'Brien, Director of Technical Services,
at Tel. 603-880-3005 or FAX 603-889-7232.
