Well, looking directly from the manual....

You use setrgbpallette() only when in VGA mode, or in IBM 8514.  From another 
book (Bitmapped graphics by Steve Rimmer...), PCX was made for the EGA display.
However, just because it was desined for the EGA doesn't mean you can't have
it in VGA!!  In fact, the newer forms of PCX were made for 256 color displays,
OBVIOUSLY NOT EGA!!  So, basically, if you can, open up a VGA screen
(640 X 480 X 16) and go to work.  And, if you want to handle the newer forms of
PCX, open up a 320 X 200 (or larger) X 256 color display.

Hope this helps...

Well, I eagerly await your agent of dismemberment....

Actually, I have no clear preference, and I'll explain why.  In all my
education (math and physics, B.S Physics UCLA 1986), only row-major matrices
were used, so I naturally think of that as the standard.  However, I have an
idea as to why so many people are switching to column-major notation.  It's
so that matrices can be post-multiplied instead of pre-multiplied!  Post-
multiplication notation accords better with the compound operators of C and
C++.  If you're writing a matrix class in C++, and you want to multiply one
matrix by another, it seems natural to define the operator `*=' as the
multiplication operator, such that:

    A *= B means A = A * B.

I was writing such a class for a simple 3-D graphics program, and I quickly
realised that the most common multiplication I wanted to do was PRE-
multiplication.  I therefore said `Screw convention', and defined `*=' so
that

    A *= B means A = B * A.

So, my solution was to change the standard C relationship between `*=' and
`*'.  Apparently, others decided it was better to change the very operation
of matrix multiplication to imply a column-major order, so that `A *= B'
would still mean `A = A*B'.

Well, in the hospital I worked in, it was used to plan new facilities and 
space renovations. Most of the hospitals here are in a constant state of 
change. They are always building new clinics, or renovating older facilities.
Autocad is a powerful electronic drafting tool, with extensive third-party 
support. It just takes a little time to learn.

For the SGI, you might want to try "Bob" (Brick Of Bytes), our

I'm not sure how robust the implementation is, but StereoGraphics Corp.

Hello,
	I've done some tests and found out that 256 is indeed much faster
than 16 color at the same resolution.  Why is this?  I tested
320x200x16 vs. 320x200x256, and 640x480x16 vs. 640x480x256, and
800x600x16 vs. 800x600x256.  I figure that that covered all the
memory ranges pretty well.  The 256 color out performed the 16 color
by anywhere from 10%-40%!!!   The only possible explantion I can
think of is that with 256 color they can to fast byte operations on
memory vs. messing around with 4bits and shifting and all that.  Is
this theory at all on the right track?
Thanks for the help.

Could someone please provide references to articles that discuss

The problem is as follows:

A laser rangefinder and colour sensor are being used to obtain
a data set of X,Y,Z, and R,G,B values for an object.  2 or
more data sets are recorded from different directions.  There is
necessarily some overlap in the areas scanned.

The idea is to combine the views to provide a complete digital
representation of the object being scanned.  The overlapped areas
would be used to position and 'lock' the different views together.

I'm looking for any work that has been already done in this area.

Thanks in advance for the refrences.

Subject: Row major or column major matrices?
Date: Fri, 22 Jan 93 17:42:48 GMT
Organization: 3D/EYE, Inc.  Ithaca, NY

I feel vaguely like I'm in a twilight zone episode.  You know, like the ones
where some guy wakes up and finds that all the lettering is backwards and
everyone is left-handed.

Someone was telling me that OpenGL allows only post-concatenation of matrices.
This seemed bass-ackwards, and after a few minutes reconfirming in my slow
turtle brain that you'd normally want pre-concatenation of matrices, I read
over the OpenGL manual page carefully.  Aha, they store matrices in
column-major form:

	a0   a4   a8   a12	a typical	1  0  0 -2
	a1   a5   a9   a13	translation	0  1  0  5
	a2   a6   a10  a14	matrix -->	0  0  1  3
	a3   a7   a11  a15			0  0  0  1

Me, I learned on my pappy's knee (well, actually, through Newman & Sproull) to
use row major matrices.  Up until today using column major matrices never
crossed my mind.  Anywell, ideas like "we only post-concatenate column major
matrices" translates into "we only pre-concatenate row major matrices".
Lovely, a new way to confuse computer graphics people (as if left vs.
right-handed coordinate systems weren't bad enough).  This is not a slam of
OpenGL - Phigs uses column major matrices, too!

It's admittedly a minor point, and really just a notational difference - the
matrices are just the same, of course.  As long as you get the matrix elements
in the right order it doesn't matter to the computer.  It's just writing it
down on paper and presenting it is where the difference appears.

Just out of curiosity, I looked at a few computer graphics books and whatnot
and how they presented 3D matrices.

Row Major users:

	Foley & VD (1st edition), Newman & Sproull, Graphics Gems series,
	Rogers books, Watt, Burger & Gillies, the Thalmanns, HP Starbase

Column Major users:

	Foley & VD & F & H (2nd edition), OpenGL, Phigs (and PEX, I assume)

So Foley et al is the only book I could find that uses column-major matrices.
Weirder yet, the first edition of Foley & VD uses the row-major form, but then
the second edition goes to column-major form!  Evidently this book's second
edition made quite an impression (or maybe just reflects some new teaching
methods present at the time), since both OpenGL and PEX adopted it, in
contrast with the rest of the research and academic community who (seem to)
use row-major matrices.

If you made it this far, take a minute and hit that "r" key and let me know
which form (if either) you prefer, where you learned it, and any other
insights you might have.  I'm interested to see if there's any correlation
with school, or age, or whatever.  I'll summarize to the net.

Thanks, and not that I'm biased or anything, but dismemberment and death to all
column-major users,

There is also a program already written that creates one gif of several gifs
for easier location. it just reduces the size of each gif and taggs a filename
to them and stores them in row coloumn form in the rows/col of your choice.
I believe it is GIFVIEW.ZIP
