HELP!  I am getting GOBS of error messages from my compiler.
Does anyone have POV Ray Trace c source that will work with
cc from HP?  Or an executable for use on HP-UX?

Yes, the customer base is smaller than the 20K units installed base
required for a specialty publisher to consider a "how-to" book on the
subject.  However, we supply basic and advanced training here in
Toronto through our customer suppport division, Alias Assist, but as a
student (?) you may not have the budget to visit us for the week of
classes.  We are in production on a series of video tutorials to be
shipped with the latest release (3.2), which (if you upgrade) should
help you out.

Hi all,
    I'm sure this has been asked before but I don't read news often so 
here goes. 
We are currently evaluating plotting software for our PC network. We have
Harvard graphics but find this is too business oriented. What we really
want is something easy to use, with an interactive graphics editor which
is capable of producing high quality scientific graphs for publication.
It needs to be pretty flexible as some overseas journals require some 
quirky formats.
There must be others out there with similar needs. So what do you use and
what are the pros and cons. In particular is anyone using SigmaPlot?
What's your impression of it?

Many thanks for any advice you can give.

Unfortunately, this does not work for workstations. If the background 
application is uses a large virtual memory space and pages regularly, 
the memory space of "idle" programs gets paged out. Try a matrix inversion
by Gaussian elimination where the augmented matrix is more than 4 times real
memory.

Whenever the user at the graphics console is in "think state", the processor
will run the background job, even if its priority in the back-of-beyond.
On Irix the kernel is locked into memory, you have a decent SCSI controller,
(at least with the machines I know of, i.e. PI, 4D/3xx and Indigo) and a bit 
of real memory is kept free for swapping, and the file system attempts to
avoid fragmentation.

Thus when you start typing into vi or at the shell prompt, you will see 
what you tye after about 10 characters at the latest, and that with a 
furiously paging job in the background.

On some other machines I don't have any problem demonstrating a one minute 
type-behind (!) with a background job that uses 3% to 5% of processing time 
with more than 90% idle time in the system.

One minute type-behind means you type "date" into a window and you see the echo 
a minute later, with the output being delivered in due course.

The other problem with running jobs at low priority is that they use up virtual
memory, with the dreaded effect of getting the Xsgi server killed when a 
substantial X applications starts.

Adobe Photoshop on the Macintosh reads and writes Scitex CT format,
can convert it to RGB, and can write it in TIFF, Targa, PICT, etc..
Two things to note: first, Scitex CT is a CMYK format, and second,
I seem to remember that CT2T and Scitex CT were somewhat different,
CT2T having no header.

Point-in-polygon has been thrashed out here - Eric Haines has the
history.  Beware of solutions whose idea of "inside" differs from yours.

Polygon-in-polygon seems to me to be a very hard problem.  Let's see: if
al you want is a YES/NO answer to the question 'does polygon P lie
entirely inside polygon Q', then:

    *all vertices of P must lie inside Q (see Eric)
    *all segments of the perimeter of P must lie inside Q
  
The first condition is necessary, but not sufficient.  The second
condition is both necessary and sufficient (but probably has
sub-problems just like the first condition).

I would expect a practical solution to this problem to consist of
several "quick-kill" tests (all giving the answer "NO") followed by one
very expensive test to make sure the answer is "YES".  I can't
immediately see any alternative to intersecting every segment of P's
perimeter with every segment of Q's perimeter (plus one Point-in-Polygon
test to distinguish between totally-in and totally-out.

You could always announce a contest...
