In order of my preference and use:

Jain, Anil K., _Fundamentals of Image Processing_. (1989) ISBN 0-13-336165-9 

Castleman, Kenneth R., _Digital Image Processing_. (1979) ISBN 0-13-212365-7

Pratt, William K., _Digital Image Processing, Second Edition_. (1991)
ISBN 0-471-85766-1

Gonzalez, Rafael C. and Woods, Richard E., _Digital Image Processing_. (1992)
ISBN 0-201-50803-6

A collegue of mine, somewhat in jest, said, when he found out that Dr.
Jain had passed away shortly before his book was published, "That's
too bad.  If he had lived longer, he would have solved *all* of our
problems for us."  Perhaps overstated but nonetheless, Jain is a
pretty comprehensive reference.  I rely on it a lot.

Castleman is a little dated, but still good.

Pratt and Gonzales and Woods sort of fill in the gaps for me.

  Windows NT - (New Technology) - a 'portable' OS and GUI... the kernel is
built around calls to a machine abstraction layer which can be 'easily' 
re-written for particular machines, so it's easy to port - sort of a new
UNIX, if you will... those of us who're excited by it see it as an answer
to a lot of the OS/wars questions on the Intel Platform, and a way to
connect to the rest of the world.  MS seems to see it as a step to Cairo
(their *next* step, in itself apparently a step to something else, i dunno,
to many d*mn steps <g>)

in a nutshell, Yet Another New OS, this one with mcuh promise.

Windows 3.x, DOS, POSIX, OS/2 16-bit character-based apps, <- support for
these OSs/environments

This is a copy from Cornell; Cornell copy is (were?) updated by author
or other researchers.

Here Freedom.graphics.cornell.edu doesn't answer (machine is off the Net).
The same with cs.uoregon.edu (no anonymous username).
It could be that above two sites are usable only at night time or beyond.

Wuarchive.wustl.edu:graphics/graphics/books/roy-hall/

Wuarchive and nic.funet.fi has equal sized files, so they maybe
are the same release and you don't have to rush immediately to take

The answer can be determined O[n] steps. 

a set of points: p[0], p[2],...,p[n]

let A(p[n1],p[n2],p[n3]) denote the angle at point p[n2] between
edges from p[n1] to p[n2] and p[n2] to p[n3].

calculate angle of each vertex:
A(p[n],p[0],p[1]), A(p[0],p[1],p[2]),...,A(p[n-1],p[n],p[0])

calculate "sweep" angle for each point (angle between first edge and
a line drawn from the first point passing through point p[m]):

A(p[1],p[0],p[2]), A(p[1],p[0],p[3]),...,A(p[1],p[0],p[n])

The polygon is convex if and only if the angle of every vertex is
between 0 and pi and the sweep angle p[m] >= p[m-1] for all m.

There are (at least) two ways to go:

  (1) get a version of latex for DOS (if such a thing exists) and use it to
      output text.
or
  (2) ftp to cad0.arch.unsw.edu.au in the /pub/rayshade/docs directory are 
      the files:  guide-b.doc (MS-Word 5.0 format) and guide-b.rtf (Rich
      Text Format).  

      These files are *slightly different* from craig's docs:
        - the pages are formatted for International A4 paper (297x210mm);
        - "vector arrows" are replaced with a small arrow after the identifier;
        - some typos in craig's text are fixed.

hope this helps
Stephen.

        I am in need of code to rotate a bitmap.  Specifically, this is for
Turbo C++ putimage() style bitmaps, and has to be able to rotate an image
through the entire 360 degree range.

        I've got the basics down, the only problem is that my bitmap is always
mirrored.  The left and right halves are exactly the same, even though the
bitmap is rotating correctly (at least, the left half is, anyway).  I've
managed to speed up the routine by using a table of sin and cos values, but if
anyone has any other ways to speed up the routine, I'd appreciate it.  I need
this thing as fast as I can possibly get it.

        Please send any replies through the mail, and I'll post the working
code for the routine if I ever get it working.  If this is a FAQ, just tell me
where to find it and I'll still appreciate it greatly!

I draw wide lines the same as I draw filled ellipses and wide circles. 
I Basically build a defintion of the wide line in a scanline buffer (by
drawgging a rectangular pen, similar to quickdraw). This scanline buffer
is then rendered with my high speed scanline filling routines (which 
means it can also be pattern filled and all that). Quality issues such
as line capping etc can be coded by making small mods to the routine
that actually draws the line definition into the scanline buffer.

I have found this approach to be adequate for my needs, and reasonably
fast. I'd be interested if people know of any better ways to do this...

	So where do you tell if it's convex?

	I do not read the algorithm very carefully, since in
	general I am very dubious of any claim that you can
	determine the convexity of an arbitrary polygon in O(n).
	I think the lower bound of this decision problem is in
	fact O(n*ln(n)) based on the decision tree model (as
	is argued for sorting.)

>I thought Wang went belly up recently.

Let me clarify the information you may have on Wang Laboratories:
     On August 18, 1992, Wang Laboratories filed for protection under Chapter
11 of the U.S. Bankruptcy Code.  This was a painful decision for the company,
and one that it had tried for years to avoid, but it was a necessary step in
management's efforts to turn the company around.  It will enable the company
to complete the restructuring begun three years ago, which could not be
accomplished in any other way, while also allowing the company to continue
serving its customers without interruption.
     More important, Wang now has an opportunity to remain in business.  Wang
expects to emerge from Chapter 11 as a smaller, more focused, more competitive
company.  Wang's business will focus increasingly on providing service and
support to its customers around the world and on the development and
application of advanced technology software and systems.
     The Chapter 11 filing will not interfere with Wang's business
relationships with its valued customers around the world.  Wang will continue
to operate during the reorganization process, providing the high-quality
services and systems its customers need and expect and developing new products
vital to both their and Wang's own future.

    It has MIT's xterm version as well as others, based on MIT's,
    versions. They are: cxterm_CHIN, kterm_JAP, exterm_MULTIBYTE, 
    volume9_colxterm and ximp.

    Unfortunately, there is not much information how to build (and
    use) actual xterm. 

    One thing it is huge and all this stuff won't fit my hard disk.
    It is obvious, that I don't need all this software under X11R5.

    I am running SunOS 4.1.3 version and have X installed on my machine.

    SUN has xterm executable and man page dedicated to it. However, 
    I need to modify source and build my own.

    Does anyone know what is the fastest way to build xterm from the
    software ?

Hi,
I am looking for public domain software for
direct volume rendering. I don't mean general 
ray tracing software, but other algoritms 
such as volume buffer.
Can anyone help me with this problem?

Thanks in advance.
