There is a PD package called Imagemagick that has a program called animation
that will display a series of pictures. I think it creates a common color map
from the pictures and then displays them sequentially. You can adjust the rate
at which the pictures are displayed. The latest version supports many different
formats including GIF and JPEG (if you have the JPEG library).
The package can de found in contrib/ImageMagick.tar.Z on export.lcs.mit.edu.

I hope this helps.

How does one read pixels in 16 color planar modes?
There seems to be only 2 read modes.
1 comparing 8 pixels to a color compare register.
2 reading the byte plane by plane.
It seems to me that the 1st method requires up to 15 compares
and the 2nd needs 4 reads.
Surely there must be a better method (NOT int 10h service 13)

The problem with xv is that it doesn't do reflections.  You can do
reflections on the root window etc. but it won't save the gif as the

    Unfortunately, I haven't yet seen a paper that discusses these.
However, at SIGGRAPH '92, Meta Corporation, USA had a booth that exhibited
their Meta Editor (tm) software.  I was very impressed with the images they
produced; they modeled a female torso (cut off at the shoulders, neck and
knees) that looked very, _very_ good.

    Heh; you KNOW you're a nerd when you look at a nude female torso and go
ape over the modeling.  Apparently other folks were also impressed, since
Meta Corporation is currently scrambling to get some posters out.  They had
a great one of a nude swimmer (complete body) that was absolutely beautiful.
They got so many requests for posters that they've decided to print some up
and sell them.

    Anyway, I've digressed (as usual).  For some good preliminary
information, you can call them at 212-787-4476 or send them a FAX at
212-787-3789 and have them send you some information.

    If anybody else has any paper references, I've love to see them.

    By the way, I know there's a raytracing bibliography (I have an old
copy); is there a general computer graphics bibliography out there
anywhere?

Note that how you understand articles doesn't depend only on the
writer, but also on reader.

How I should understand what you write above:
"...after reading Mr. Kouhia's very polite, very helpful reply..."

What you mean? You surely wrote opposite ideas via e-mail.

I specially wrote that the article was supposed to take seriously,
not as yet another flame as you did.

In my article I wrote:
 -what is good to write first (and pointed out that author didn't
  write as expected)
 -I wrote where the problem was, so that the author can locate it
  and understand what I mean
 -I wrote an example what kind of announce to not write; the example
  was a bad case, so that people can understand the problem better
  (from a less bad examples the main problems may not be visible, thus a
  bad example)
 -and finally, I requested to write the description for L-system;
  however, I didn't write it myself, because I don't have any references
  and it is not a good idea to write an inaccurate description

So, as you can see it was attemp to help.
Always, when people write a reply to correct something and directly
point out that the author was wrong, the reply is a sort of flame
(it is just how people understand what is a flame).

But think about if I really had written a flame?
What kind of that had been?

I have an STB Evolution with the original Bios rev 1.0 (there is a newer one)
and it works flawlessly under Windows in 256 color, 16 bit, and 25 bit true 
color modes.  Also works flawlessly in all 256 color modes with Fractint and 
with Cshow when using their VESA driver. My only gripe is that the 24 bit
mode is awfully slow. The 256 color and 16 bit modes are reasonable.

     I am looking for a way to generate a color on a workstation that closely 
matches a given sample from a color plate.  

     I have tried scanning the image (24 bit scanner) with little success.  
The scanning software only gives percentages of the R,G, & B components.  
Using a little math I converted each percentage to a value in the range 
0..255 (24 bit color system) for each RGB component.  The problem is that 
the new color doesn't look very much like the original sample.  I know 
that the monitor can be adjusted to do minor compenstaion, but it still 
doesn't get close enough to the original sample.

     Is there a better way to accurately reproduce a color sample on a 24 bit 
workstation?  Is there something I have missed in the conversion?

     Please E-mail any responses directly to me since my news feed is several 
days behind.
