Ryan C White,

The best way to do what you want is not via ARexx, it is via the public
interface. This allows you direct, low-level access to the image buffers,
where you can use C or ASM to read and write the data. It is VERY easy
to use. ARexx is far too slow for a pixel by pixel operation on a 24-bit
image; it's just not designed for that kind of throughput.

I'm in the same boat.  I've written a ray-tracer or two also, but up until
this discussion started I'd never heard of scan-line rendering.  Where
can I find out more about it?  Anyone care to mail me a brief description
of it?

I tried to follow the funny face tutorial in the Imagine Companion book and I
experienced some problems...using both versions 1.1 and 2.0 of Imagine.  
I created the face outline ok, and then added the primitive plane to slice it
on.  In the book, it says to move the plane so that it bisects the extruded
template.  I did that.  I also picked the template, then the plane before the
slicing.  The error I got said something like edge too close to another edge
or something....?  Anyone have a clue what I might be doing wrong?

Yury,

It may well be that there was a PD program out before Oct 1/91; if so,
more power to the writer. I should have said commercial, I usually do.
Guess I lost my credibility now (sob)   <grin>

Regarding the DCTV support for reading; it is really quite good. And until
Digital Creations provides another way to do it (like, with a library),
You can't say we did it the wrong way, because we had to invent the way
we did it! We even had to figure out the display format, and again no one
else has done that (at least, that I am aware of). We'll have no problem
using any library support Digital comes with, if and when it happens.

I have a 3000 with 4 Meg fast on the motherboard and an old A2091A controller
with 2 Meg 16 bit, this makes a total of 6Meg fast and 2 Meg chip. I can 
morph two 752X480 24bit Toaster frame grabs with an undo buffer with no problem. 

The morph in Deluxe Paint IV is not even close to the same thing as the morph
in Image Master. The morph in Image Master is incredible. One has very fine
control over the morph and the results I've had are stunning.

In Image Master, all images are converted to 24 bit, with the extra bits
padded when necessary. Your "stupid HAM" image is stored as a 24 bit image
in memory. What you are limited to is not the number of bitplanes but 
the resolution of your image. Try morphing on lower res images.

The morph process is a compute intensive procedure. It has taken as long as an
hour to do one frame on some of the images I have tried. I would hate to think
how much longer it would take swapping to disk. I would rather save my pennies
and buy more memory for this type of operation. Leave virtual memory for 
word processors, DTP, etc.

I believe it is ony a 24 bit display board....no alpha channel information.

Anyhow, the board is in a pre-production phase right now, and all the
software is being modified to ensure compatibility with the 24 bit version of
the board.  I have no information as to the upgradeability of the 8 bit board
to the 24 bit version. but I will post all information regarding these boards
if there is interest.

That's a "smart-bomb" function.  Notice what happens when you do it and there's

	I suppose this is my windmill.  For everyone who doesn't believe
24-bit color is enough, let me ask you this:  how many greys can a
normal 24-bit RGB screen generate?  Do you think you can see more
than this number of greys simultaneously?

	I don't think that the the limit of our color perception is
as simple as "a few million colors".  It depends a lot on what
other colors we see around the colors we're trying to perceive.
Edward (is this his first name?) Land apparently did a demo
a few years back at a Caltech lecture where he put up a quilt
of colored paper.  He then pointed to two different patches and
you apparently could see two very distinct colors (red and green,
or something like that).  He then took a spectrometer and measured
the colors of the two pieces of paper, and the spectrometer said
they were emitting exactly the same spectrum.  In fact, the two
patches were cut from the same piece of paper!

>Kiernan "Who cares if they are all raytracers" Holland. ;-) 

	But raytracers can generate some really horrendously fake, ugly
scenes.  I'm not saying anything can do better on those scenes
always, but usually something does.

Edouard Boily,

Yes, this demo is displayable on a stock Amiga system, using "showanim",
a PD tool which handles ANIM OP-5 compressed IFF animations.

Imagemaster can produce 24-bit output, many other formats, and anim output
(as of today, when the anim drivers were released from testing :^)

The early demo anims were made with PD tools from multiple rendered frames.

I rest my case. :)
Caligari is not a raytracer.  I would imagine that you are looking into getting
into 3D graphics, and would like to find a nice PD _renderer_ that has a decent
interface. There are none.

>2) Also, how does one produce ray-traced animatoins?  Does Imagine do this, or

The same way you create all 3D rendered animations. :)
Imagine does generate anims from within the program.

Yep, sounds good.  Might even make some nice solid model pics too. :)

If money is such an issue, I would suggest picking up a used copy of TurboSilver
or SculptAnimate.  TS has better output and doesn't suck, and SA is easier for
a beginner to pick up.  Both generate anims within the program.
Imagine 1.1 can be found for a pretty good price now that 2.0 is out, and I would
strongly suggest that one since it has all the advantages of TurboSilver, and has
a better interface (IMHO) than SA and doest SUCK like SA does. :)
Do I sound bitter?  It probably isn't because SA 4D can not generate an anim in
Scanline Painting mode when a take is loaded and BytemyButt refused to address this
bug and shortly after jumped ship to the Mac.  $500 down the drain!!

The RenderMan term is "displacement map".  Hard to do in a
raytracer with mathematical objects like spheres, but
easy to do in software that uses micro-facets (surfaces
broken into very small polygons).  You could raytrace
that too, but by the time that's done, there isn't much
point.

They WERE the first company with an 040 board, period. When RCS was
up and running under 1.3 with copyback ON , PP&S (this is not a knock
on the PP&S board, it's just fact), the PP&S was still in beta and
the demo board they sent up here, failed to do it.
(For all: again, I am not inferring that the PP&S board has a problem,
it doesn't..this was just a little history lesson for K.)
