The main reason for speed is the usage of MCGA (320*200) graphics,
mode 13. It's very fast due to small memory-requirements:
only takes 64000 bytes to get 256 colors with this res. This means,
that only one video-mem plane is needed - this is very suitable
for various reasons; one of them is simple algorithms for spanning etc,
and for instance fast swapping from extended memory to 0A000h is possible.
I've used 4-5 Mb/sec datastreams max. on this basis in my Ray-Tracer-
Animator project (about 72 frames/sec) with my 33MHz 486.

When high speed is combined with highly-smoothed and optimized palettes
(so the low resolution doesn't seem so bad), various classical
demo-routines and DMA-controlled music on background, miracles can be done.
One point in fast-3d is that almost all calculation in pre-done in tables
even up to address to each *row* on the screen. And I promise that these
3d-algorithms are somewhat taken-to-their-limits - though improvement can
always be done... In fact, Unreal ain't even very close to it what _can_ be
done with 386/486s...

About VR applications I dunno know much, but basicly same algorithms go
also for them - though physically (i.e. mem addresses, resolution etc.)
vary, still the optimized ("true") 3d-handling always gives lots of speedup.

>Well?  Where is it then??  :-)

At least in nic.funet.fi. (BTW: this demo comes from _Finland_ :)

Hi,

I am setting up a Fax server on my network, the sending part is great, but the
receiving part is not so convenient. Since received faxes are in Fax format (bitmaps),
there is no way to be able to tell from a fax's header which person it's supposed to
go to, since the entire fax is one image. I would like to have a setup that can
recognize a predefined header in a received fax, and forward it, through e-mail
to the appropriate person. Does anyone know of a reasonably priced OCR system that
can do that for me. The fax is running on a Unix Sun network.

Thanks for any info.

Robert,

You'll get all sorts of reccomendations for Tufte's books - by all means,
check out
a copy from the library, or buy yourself a copy (There's two out at the
moment, "The
Visual Display of Quantitative Information", and "Envisioning Information",
with a 
3rd either out or due out RSN). Admire the beautiful artwork, and marvel at
the folksish
wisdom resplendent throughout both books. Then, stick 'em on the coffee
table with the
rest of your "art" books - that's about what they're good for.

Once you've got past the requisite Tufte stage, you can start to look into
some of the
more useful work in the subject:

Bertin, Jacques: "The Semiology of Graphics"  (originally in French,
English
	translation by WIlliam J. Berg, University of Wisconsin Press -
unfortunately,
	out of print now - try the library)
 "Graphics and Graphic Information Processing" - Translated by William J.
Berg and Paul Scott,
  Walter De Gruyter, Publisher.

Cleveland, William: "The Elements of Graphing Data" Wadsworth Advanced
Books and Software.

Tukey, John: "Exploratory Data Analysis" - not really a graphical data
representation book,
per se, but contains much in the way of useful insights into producing
useful data representations.
Addision Weseley, pub.

Those are some of my favorite's - you probably also want to check out the
last couple of 
years of the Proceedings of Visualization 'xx - there's been a number of
works published
lately which deal with choosing the right representation given a set of
data and a set
of interpretation aims. The works of Jock Mackinlay, Steve Casner, Phil
Robertson,
and Wehrend and Lewis come to mind, although I'm sure I've forgotten a few 
- pointers to these 
and others are all in the proceedings.

"How to Lie and Confuse with Visualization"


	People have lied with statistics and maps for years.  Now it's 
time to look into lying and confusing in the field of visualization.  
Your big chance to do just that, in the open, will be in this special 
session of Visualization '92 Conference on Tuesday, October 20, 1992 
at 7:00 pm.  You are invited to bring with you visualization lies and 
confusing articles, yours or others, on 35 mm slides or video.  During 
this evening, it will be allowed to lie but not to borrow credit, so 
please do not forget to mention the producers' names.  After the 
informal presentations and truthful debates, the audience will choose 
the biggest (visualization) lie for 1992.  When the evening is over, 
lying will be outlawed again.  Then, we will be all able to benefit 
from this teaching of what it takes to produce realistic and faithful 
visualizations.

	Reservations and advance submissions are now being accepted 
(c/o Nahum Gershon, The MITRE Corporation, 7525 Colshire Drive, 
McLean, VA 22102).  Both are not required but are strongly 
recommended.  For more information (genuine!), please contact

I don't know whether, like SGI machines, the snake can be set to
produce a PAL or NTSC rate/size picture.  If it can, you will need
a PAL or NTSC encoder and feed the output straight into a recorder.
If not you'll need a linerate convertor.  A decent coder costs
about $(UK)1500, although board level version can be a lot cheaper.
The cheapest linerate convertor will be closer to $(UK)10,000.
There will be a lot of information on this in the archive, about six
months back.

Yes, there is an excellent book by someone named Tufte.  Sorry, but I
don't remember the title offhand.  I think that Eugene Miya refers to
it in one of the FAQs he maintains but I may be mistaken there.
Anyhow, you see it advertised all of the time in magazines like
Scientific American -- it's the one with the chart showing the
progress of Napoleon's failed assault on Russia in it.

Do you mean for non-PostScript printers?  If not, all you use is 'pr'.
Our experience of software emulators for PostScript is that they
are best avoided - it's better to upgrade the printer to handle it

There isn't a unique mapping.  The Munsell system is two sets of chips
(one matte, one glossy).  Any of the HSV, HLS, RGB, YIQ, YUV,...
systems encode light, whereas Munsell is encoding reflectance.
Therefore you have to nominate a light source.  There are a number
of standards (CIE ILL A, B, C, D, D sub 65,...).
This leads to the CIE XYZ, xyY, Lab and Luv encodings.

A useful reference is G A Agoston "Color Theory and Its Application
in Art and Design" Springer-Verlag ISBN 3-540-09654-X or 0-387-09654-X.

A number of papers point to W B Cowan "An Inexpensive way for
calibration on a colour monitor in terms of CIE standard coordinates"
Comp. Graph. 17, 3(July 1983) 315-321 as being a useful source for
algorithms for interconverting RGB etc and CIE systems.  I am actually
trying to track that down this morning for another project!

I'm trying to create files of polygonal patch data from RenderMan .RIB
format files.  This requires tesselating the surfaces into triangles
either with or without surface normals at the vertices.  Has anyone
ever written a utility to do this, or anything similar for some other
data format?  RenderMan supportes geometric approximations in its
rendering, but since my version of RenderMan doesn't handle raytracing
I need to dump the files into polygonal patches to send to a
raytracer.  I can't seem to get at the RenderMan objects to extract
the tesselated data points that it creates itself.  If anyone knows
how to do this also, that would be a far superior solution.
