  I think it is more than just advanced computer graphics.  It also
involves being able to visually represent data in ways that make
sense and perhaps in ways that will enhance it's meaning.
  It also involves manipulation of the data to enhamce understanding.
A good example of this is protein folding.  In many cases it is not
known how a protein is folded even though you know what makes up the
protein.  So you visualize the protein and play a whatif game and see
the results.  Much better than drawing on paper all the possibilities.
  Just my opinion.

It is of course important to use the right jargon, but I think 
the reason for the new new term was that "icon" could  be 
transformed into "eyecon" which would mean that the term "earcon"
would carry the pun further, and preserve the secondary reading. 
 
Whether to adopt this more humoristic term instead of the more 
correct one is not anything I want to discuss here, since I 
don't know which one to promote, but I think the "earcon" term is 
cute, myself. However, I am not a native English speaker so I 
wouldn't know if it was acceptable in the language.

Hi,

In regards to the PCM encoding, I would have to some digging now to find
the details.  If I remember correctly it is 12 bits per sample and is 32K
samples per second and there is some form of compression involved.  The
sound I am wanting to record is based on one or more of the data chanels
associated with the graphics.  I want perfectly synced sound with video.
Right now, I cannot do that.  In the next year or so when we get an SGI
Indigo, and can convince SGI (or do it ourselves) to write the software
to lay down SMPTE time code with the audio onto DAT tapes, we will be able
to send a DAT tape along with a SMPTE time coded video tape to an outside
production house that can do the merge.  With PCM onto BetaCam we won't have
to pay an outside production house and suffer the delays.

The sound creation is likely to not be done in real time, but that is not
a problem as playback can always be done in real time.  One thing that I
have thought about doing is to record the audio at the same time we preblack
the tapes (this is when we lay down time code).  The only problem I have
with that is determining (within a 30th of a second) of when a sound starts
relative to a given time code.

I've used the fsn file navigator and I'd agree with Charlie. I also haven't 
had it long enough to tell how useful it is but it seems like it should be. In 
the same way I'm used to the spatial layout of piles of papers on my desk I
I should be able to get that same kind of orientation with the file navigator. 
Also the  
fact that it animates movements thru the landscape maintains your ability 
to stay orientated as you move about. The spotlight is a nice touch. 

All in all its a neat little application. I'd like to try this on a
complex simulation interface I'm working on. I'm having problems providing
enough information about the current state to keep the user from getting

Hi,

I manage a Visualization Lab, and currently we have systems from SGI, Sun,
IBM, Apple, HP, and Stardent (well it used to be Stardent).  We are now
shopping for a PC clone to round out the equipment list.  I have not paid
much attention to the PC side of the world and could use some help in
specifying what should be on the PC in terms of software and hardware.

We support a wide variety of scientist from those who work on the very
small (atoms) and those who look at the very large (quasars).  I would
be interested in both general purpose software and more specialized 
software to support molecular dynamics, chemistry (in various flavors),
remote sensing, fluid dynamics, acoustics, optics, radar, and meteorology
to name the biggies.

We are also interested in making animations.  Currently we have an S-Video
deck, and have access to a D-2 deck.  At some point in the future we may
have a BetaCam deck.  If we get the BetaCam deck we would like to be able
to record audio in single frame mode (PCM encoded sound on two of the video
scan lines that are not displayed).  Does any one know of a board/software
combination that will support this?  Any other hardware/software suggestions
are welcome.

Subject: What visualization is
Date: 11 Apr 92 01:14:45 GMT
Organization: Wetware Diversions, San Francisco

Most helpful to this thread is forgetting 'scientific' and focussing on
'visualization'.  I say visualization is using the mind's sophisticated
visual system to reduce complexity of data in order to comprehend.

If you add audio to the scheme, or tactile feedback, this would be 
'sensation'.  

Try funding scientific sensation.

Really, saying visualization is glorified graphics (for the sake of opening
new dollar channels) is like saying teaching is printing textbooks and 
building chalkboards.  [this analogy was supplied on the fly by inspiration]
Graphics is draw_line, sample_pointer, set_color, etc.
Glorified graphics is raytracing, radiosity, blobbies, NURBS, and BURPS.

Visualization uses these techniques so that the message can be realized
through the media.  It is easier to look at good graphics (nice shadows,etc)
allowing focus to remain on what the visualization represents rather than
the visualization artifacts themselves.

There is an unfortunate though extant sense that pictures are used by swindlers.
Marketing folks use sweet looking slides to schmooze the client, management,
bean counters.  Clear thinking academics are suspicious of 'video'.  

This is understandable, especially given the knowledge of how the visualization
process is done.  There is an fine line (of fractional dimension :}) between
accurately representing data and creating a convincing representation.
I trust you understand this (remember dropping a few titration results in
Chem 207? sure you do).

OK - extrapolate.  Many variables, many ways to reduce to visible (and audible)
form, many points to prove.  Politician A wants to 'show' that N% flat tax is
'good' for the 'country'.  Politician B wants to 'show' that reducing 
assistance to welfare mothers when they have additional children will be
'beneficial'.  Stockbroker A has a hunch about P/E ratios for companies
with a Browning coefficient above 9.  Tools, people.  The right tools
can give us a handle on these things and we have hardly scratched the surface.

Post it.

Unfortunately the NuVista+ card will not fix this problem.  The Mac uses one
pixel wide lines and fonts for the normal displays.  This works fine on a
non-interlaced monitor, but it creates the flicker you spoke about when it is
converted into the interlaced environment of NTSC.

It can be fixed in several ways, none of which is really too efficient.  The
old toby video card has the capability to produced "convoluted" RGB output in
NTSC as does the 8*24GC card.  The problem is that then you need an encoder to
produce composite video to record.  The "convoluted" video will remove any
flicker by averaging adjacent lines in the NTSC output. This can be fed into
the NuVista+ Card and it will provide the composite output for recording.

The most objectionable flicker I've noticed is the menu bar. (After a few days
you can grow used to it.)

You can also try using resedit to replace the menu bars and anything else that
flickers with a pict that has wider lines. (I haven't tried this but I think it
may work.)

If all else fails, I have seen some very good Mac screen simulations done in
MacroMind Director.  MMD looks great on the output of a NuVista in NTSC.

There may be better ways but these are the only ways we have been able to fix
the flicker problem.

There are a couple of techniques which can be used depending upon what caused
the image to be out of focus in the first place.  For your standard
"fuzzy" picture, you can run the image through a high pass filter and
then add the result back to the original image.  A Laplacian filter
can also be used on the image to emphasize the higher frequencies.
Alternatively, you could scan throuh the image and take the partial
derivative with repspect to the scan direction and add that back to
the original.  You would need to do this for vertical and horizontal 
positions.  Sometimes though, the image is blurred due to camera
motion.  There a techniques which give *very* good results in
recovering the original image.
