Greg, you might be interested in the fact that this is the basic

   This is true, but it is only useful in theory.  I have written a lot of
   code to manipulate polygons and have never seen a polygon like this.  If
   my code ever produced a polygon like this I would either shoot it, or
   have it insert two new points where the X is.  Does anyone really use
   (allow) polygons where the edges cross?  For what reason?

   As far as I am concerned, taking the convex hull is a practical and fast
   solution to the given problem.  It annoys me when theoreticians bring
   up these degenerate cases that never arise in practice to claim that an
   algorithm doesn't work.  If my code avoids those cases, then it does
   not fail for them.

   If the original poster was asking a theoretical question, never mind.

I'd like to build a video "helmet", and am seeking information.
Namely:

(1) a discussion of display and optics options/configurations
(2) a source for the appropriate displays and optics
(3) a discussion of the graphics involved (stereo stuff: 
    viewpoints/angles, etc - I'm pretty comfortable with UG-level
    3D graphics)

Also, has anyone combined lcd-shutters with a two-display, one (split)
video signal system (i.e. avoided the need for two separate signals,
one for each display/eye)?

Its about 1.4 Megs long and just squeezes on a 3 1/2" HD floppy disk.
I don't have a soundboard (only a D/A) but the graphics blew me away.
It is by Future Crew, and needs a 386 or greater to run on.

I also recommend to anyone with a D/A (featured in Modplay/Modedit) to get
another Future Crew demo call Crystal Dreams, completely mid-blowing, and will
run on a 286.

Both are available on ftp.uwp.edu, part of a collection of 32 demos, all for the PC.  Have fun!

Hi,
we have now a working 

24 bit to TV converter box.

It works together with the Genoa 7900 ET4000 true color board
at 640x480x24bit.

It gives Video (FBAS) and Y/C (SVHS,HI8) outputs.

There are PAL and NTSC models available of our 24 bit to TV-box.

It is an external unit and connects to the RGB outputs of the Genoa
7900 SVGA card.

It gives RCA (cinch) video output and Y/C via SVHS connector.

Price is 349.-DM incl. 14 % VAT in Germany.
Together with the Genoa 7900 we sell it for 669.-DM incl. VAT.

It is the best combination to record still true color pics to video
tape.

Hi,

I have a DXF file (about 550kb) of a map (of Namibia and its
districts [=counties]) and want to translate this into the
MapInfo format.



It should look something like this:

"district_n",n
x0, y0, x1, y1
x1, y1, x2, y2
.
.
.
x(n-1), y(n-1), x0, y0


In other words n number of lines each defined by its beginning
and ending coordinates.

The districts are unfortunately not marked in the DXF file so
I will have to find the beginning and end of each district
myself, but this is not a problem. 

Any ideas would be greatly appreciated. I do read this group
but email works better.

The "problem" is because wgnupolot used separate windows for the plot
window and the command line.  To see the plot-windows, just switch to
that task.  Or just resize the windows to have the plot window and the
command window side by side.

the caption. It worked perfectly.

I can't remember where to get rotating.sty from, but
there are several latex archive sites that are sure to have it. Failing 
that, email me (Alistair Scott   afs@tauon.ph.unimelb.edu.au) and
I can mail it to you.

Rotating.sty is also nice for vertical labels in tables. The only
drawback, is the limitation of the previewer (xdvi) it can't
do rotated text, but it defaults to horizontal placed at where the
line would be.

Anyway, give it a try.

I think this is a great way to go.  Such an approach would make it much
easier for custom add ons to be generated and shared.  It would also make
it fairly straightforward for people to take existing codes which use
some PQRST copyrighted modules and convert them to use the gnuplot interface
and modules.  I've wanted to do this with lots of codes for portability
and increased driver capabilities, but right now it takes too much effort.
