I've used the Video Blaster, as I'm a technician at a PC-clone assembly
shop.  It's a glorified video-in-a-window flashram setup.

What it does is read in your choice of 3 different video signals (a simple
switching setup) , and via the Almost Never Used VGA Option Connecter pipes
it back out your VGA port.  

The things it can do well are pretty much this: display video in a window, any
size up to 640x480.  Decent realtime scaling of the image.  Snap a SINGLEFRAME
(NO motion recording possible) and save it in about 6 different formats (including decent JPEG implementation) up to 24bit.  Decent luminance and colorkeying.
It also passes the audio through with a software controlled mixer, nothing special there.. (no digitization).

Basically, most users buy it for a video digitizer, or a "watch teh football game whilst I happily work in MS Windows".  The DOS support for it is rather cheezy at best.

Mixed with a SoundBlaster Pro CD rom kit, it makes a decent 'multimedia' setup,
that elusive standard tha	t MSDOS machines keep reaching for.

It is in no way, in my opinion, comparable to a Video Toaster.  You can't
even write to its memory like a frame buffer.  video in, video out, mabye you can change the size and key a few things.

  -Tugs

 (please excuse the AWFUL formatting and typing; I'm using VI on a machine with an improper termcap, and growling at myself for doing so)

PS: if anybody wants specs ont he Video Blaster, holler, I'll type them in.  I've had one on "Demo try" in my home machine for 2 weeks.

What about the ol' Back to the Future demo??
When DCTV first came out they use to run the last 5 minutes of Back to the
Future III off an A3000/25 with a Trumpcard pro HD controller and 16bit
sound card.
It looked just like it was comming off video.. PERFECT! 5 minutes at 30fps
with 16bit sound!
From my own experience however, a complex anim will slow on even an 030
50mhz (Havent tried an 040) but I suppect it can be done with a good HD.

This is definately workable. However, is the 3.5" drive a hard disk? If
it is not, you had better get one. DCTV or 24 bit frames can take up a
good amount of space, 24 bit frames take up the most space. One thing
you might do is look into a floptical or a removable drive like the
the Syquest. I think you will get more storage per dollar this way and
you will have backup capabilities.

Your biggest problem will be getting it onto some kind of media like video
or film. You will need to single frame onto the media. The Amiga, while 
having excellent playback capabilites is just not fast enough to play back
animations at 30 fps, especially DCTV frames. And you will have a hard
time getting it off storage into the machine at 30 fps without spending
some bucks for some special hardware like Editmaster from DMI, which won't
work on a A500, anyway.

A video tape recorder capable of singleframing will likey cost about $3000-
$7000. You will also need a singleframe controller and a timebase corrector.
You could use your 8mm cameras cheaply, but as you know, the quality is
not very high. I have had success recording my animations onto 16mm film.
I have a Bolex which cost about $100-125 and can singleframe. I tried to
build a controller for it, but since I am no engineer, I didn't totally
get it working. So for now, I do the exposures by hand, which is tedious,
but does the job.

Actually, the bow-tie polygon is not so unusual as it seems. Many people
who would claim that their data is "bowtie-free" would be surprised. The
most common bowtie factory is a quad as part of a surface (like a height
field or z=f(x,y) function plot) with heights (toward the eye) like:

    5------------0
    |            |
    |            |
    |            |   E
    |            |
    |            |
    0------------5

You look at this thing from the top, and all is well. You look from 'E' and
you will see a fine bow tie!

Yes, you are right. Although, with the given P0 Sloans algorithm will
successfully flag this poly as concave in the second loop. However, if P0
is vertex 4 or 5, in the above diagram, then it will fail.

DKBTrace and POV run on just about any <= 16 bit machine.  It was originally
written on an Amiga.  Runs on UNIX boxes, OS-9 machines, PC, Mac, VMS boxes,
etc.  It's the most portable raytracer around.  D. Buck and the POV team

Yes, there will be a Graphics Gems IV, and I will be editor for it.

In case you're not familiar with "Graphics Gems", it's a series of books
published by Academic Press containing C and C++ code for common graphics
problems.  The articles and code are contributed by people all over the
world.  The code is available by anonymous ftp from princeton.edu
(128.112.128.1) in the directory pub/Graphics/GraphicsGems.
Andrew Glassner edited the first volume in 1990, Jim Arvo
edited "Graphics Gems II" in 1991, and David Kirk edited
"Graphics Gems III" in 1992.

We've decided to bring out Gems IV in 1994, not 1993, to keep the quality
of the series high.  The deadline for contributions is in the late Spring
of 1993.  Write to Academic Press (not me) for more detailed information
about how to contribute:

    Graphics Gems Editor
    Academic Press
    955 Massachusetts Ave
    Cambridge MA 02139

or email jswetland@igc.org .

And if you've got ideas for contributions and you'd like to discuss their
appropriateness with me, email me at the address below.
Suggestions and criticisms of the previous volumes are also welcome.

ANYONE OUT THERE FAMILIAR WITH SUN PHIGS 2.0 GRAPHICS PACKAGE?

I need help concerning the Sun PHIGS graphics package.  I am in the
process of developing a simple network drawing program which consists,
basically, of drawing circles (nodes) and lines between them (links).
I use the LOCATOR device to pick locations on the screen to draw the
nodes.  After all the nodes are drawn, the PICK device is used to pick
two nodes between which a line, using the PPL command, is drawn.  The
program refuses to draw the links.  The only clue that I have is that
the PPL command works if it occurs before the PRQPK (request pick) but 
not after.  I need to draw the line after PRQPK.  Another note:  I have
a PTX (text) command right after the PPL to label the link and that
executes properly.  I am working in FORTRAN and would appreciate any
help concerning this problem.

The CG elements were:  The Bee, the Bee-chaser (spider wasp?), The fish
and the water splashing around the fish, the tree in the opening and

All moving footage of trees, vegetation, spider webs, spiders, squirrels,

Hello. It seems that there are always people here asking for information
on such sites, but there appear to be very little responses. Is there
any such site avaliable... a "central" site for 3D object models and
utilities?

If there isn't, we may just start one. We do a lot of work here using 
Wavefront on SGI and HP machines, and already have a good number of objects
that we can make available for ftp. However, we don't want to have another
of the many sites out there with just a handful of files - that's the way
it is now and good stuff is scattered all over the net and is hard to track
down. So, if there is interest, we are willing to start up an anon ftp site
that will specialize in 3D graphics - object files (databases, libraries),
converters, utilities, textures... mostly for Wavefront but we'd be willing
to support others as well. 

So... is there interest? Is there already such a site out there I don't know
about (so I don't have to waste my time doing this - instead, we'd be willing
to contribute what we have in order to centralize things)? Post, or respond by
email to me and/or Bruce Lowry (lowry@archimedes.chinalake.navy.mil).

I have a book sitting on my desk called "Digital Image Processing"

that looks pretty good. I got it after it was recommended to me
by a Princeton Grad student who used it for an image processing

Hello all,
I may have access to some elevation data of NSW (Australia) and would
like to use Vistapro to check it out.

In order to achieve this I need to be able to put the data into so called,
alleged Digital Elevation Mtheirf err... Moteoru, oh something starting
with `M' anyway.

Could someone tell me where I can find such information. (If it's in the FAQ
just tell me to FAQ off.)

Thank youse all
