Hello:						Sept-7-92

	I'm not sure if this is the best newsgroup to ask this question - 
please advise if not.
	I would like to lay out a poster of size 4 ft x 4 ft with various
graphics and text - and I would like to print it as a mosaic on a standard
Postscript printer with 8 1/2 x 11 or 8 1/2 x 14 inch paper. Has anyone
had any experience with DTP or graphics packages that would do this ??
My preference would be for PC software since I have easy access to such 
machines.
							Thanks

							---Jim---

Does anyone know of a Vista-esque program which is available for X ?
I didnt get a reply in comp.graphics.visualisation so any ideas?

(vista is a digital terrain modelling package which is available for
 most micros. It creates pseduo-realistic images using some clever 
 shading techniques)

Hello.

I'm trying to find a decent, fast, algorithm for detecting collisions between
several objects.  I'd like to have something in either plain-english or
pseudo-c type code, as I will be implementing it on a Macintosh.  The
positions, shapes, and sizes of the object will be known to me, but the exact
number of them will vary somewhere between 2 and 75.

Any direct suggestions, or references to decent methods will be greatly
appreciated.  Please, also, post your answers.  I'm sure this is something
lotsa people would want to know.

Thanks,

Hi,
thanks for the question.

We currently have three solutions for you:

1. PC2TV converter box which is a box connected outside of the PC to
the SVGA card via its VGA connector. There must be a TSR program run
in the background to change automatically the scanning frequencies of
the ET4000 board. This works also very well with win3.1
It supports up to 800x600 with 256 colors and 640x480 with 24 bits
color (true color) on the Genoa 7900 ET4000 SVGA board.
This box is 349.-DM. It has  Video (FBAS) and Y/C (SVHS/HI8)
outputs.


2. VGA2TV adaptor. This is an internal board which is hooked inside
the PC to the feature connector of the VGA card. So the VGA or SVGA
board must have a feature connector !
The VGA2TV samples the contens of the VGA RAM into its own dual ported
RAM and gives it out with the Video scanning frequencies to its Video
(FBAS) or Y/C output.
It also has a Genlock possibility. So it can be used to do titling in
front of a holiday movie video tape running in the background of the
computer graphics titles !

Input of the external video source could also be FBAS or Y/C.

This unit is 1099.-DM and is called M2150 for the PAL version.


3. VGA2TV with integrated Flicker fixer. This is the new release of
the VGA2TV board. It has also a flicker filter for making the
Interlace flicker much less visible. It also has OverScan/Underscan
feature and the position of the screen on the TV set could be
controlled via software.
This board is of course more expensive than the older VGA2TV, but
still either cards are sold.
The new one is called M2200 and is about 1699.-DM.

Both max resolutions to convert with these VGA2TV boards are
640x480 with 256 colors ! It has the advantage, that it does not need
any software ! Just plug and it plays !



> I would appreciate the prices and shippement info.

Shipment to Norway will still add some cost. I have to calculate this,
when you really want to order a unit.

Please let me know, what you need.

	I apologize if this is the wrong group to ask for help, but it seemed
    like a likely canidate.

	I recently came into possesion of a portable graphic workstation by
    the name of MNEMOS-I made by a company called Isr Systems, Inc. in
    Trenton, New Jersey. 08628.

	What I would like to find is any information related to the internals
    of this beast. I want to program an application for it. The unit has a 
    80c88, TMS34010 and a 6845 graphics display chip in it. It also has a 
    built in scsi port and came with a sony cd-rom drive. I know (or at
    least strongly beleive) that it has drivers in rom for the touch screen
    that covers the lcd display and any information such as memory maps,
    schematics or any other information as to it's workings would be greatly 
    appreciated. The phone company has no listing for Isr Systems in Trenton
    so any info about the where abouts or history of the company would be
    also appreciated.

	Please e-mail any responses as I have never read this group before
    and do not want to waste any futher bandwidth in a group I do not follow.
    I do read the comp.robotics group regularly if mail bounces and you want to

Subject: Polygon Decomposition & Delaunay Triangulation
Keywords: polygon decomposition triangulation voronoi Delaunay
Organization: Computer Science, Monash University, Australia
Date: Thu, 10 Sep 1992 05:52:46 GMT

I have a problem with decomposing an arbitrary polygon into a set of
optimal triangles.

At first, I considered using Delaunay Triangulation for this task, so
I had written up a SGI GL-based GUI for Delaunay Triangulation using
sweepline algorithm. When I fed a set of points into the program, it
turned out fine and did produce a mesh of optimal triangles over the
points.

However, the problem arises when it is applied to decomposing a polygon.
Consider a hook-shaped polygon (ie. extremely concave), the sweepline
triangulation algorithm tesselates the vertices without considering the
integrity or structure of the polygon. The final tesselation would have
triangles partially inside and outside the polgyon and hence would not
serve to decompose the polygon.

What I really want is to be able to decompose an arbitary polygon (with
no hole in it) into *optimal triangles*. I already have code to decompose
such a polygon into triangles what are not optimal at all (the algorithm
repeatedly finds a valid triangle and removes it from the vertex list,
until only three vertices are left) but the code does not serve my need.

Could anyone please suggest how I might modify the sweepline algorithm to
cater for polygon decomposition, or direct me to some other sources of
generic optimal polygon decomposition algorithms, or anything pointers?

Thanks in advance,

Edward

Is there a program that will convert an image that was scanned into an

image is only black and white, so it seems that there would be an
algorithm to detect the outline and generate lines and arcs to

Hi -

There was a file posted to the comp.infosystems.gis newsgroup some
time ago titled "Earth Sciences Resources on Internet". It has a
listing of anonymous FTP sites for earth science data, including
imagery. The sites include: aurelie.soest.hawaii.edu for AVHRR
images (directory pub/avhrr/images), ames.arc.nasa.gov (images from
Magellean and Viking missions etc., (directory pub/SPACE/CDROM),
vad02.larc.nasa.gov (Landsat photos in GIF and JPEG format -
directory pub/gifs/misc/landsat), and many others.  The entire file
"Earth Sciences Resources on Internet" is available, I think, via
anonymous FTP from csn.org in the directory COGS under the name
"internet.resources.earth.sci". The file should be a big help. 

Good luck.

since you obviously know about Internet and seem inclined to post, consider
inquiring about the concrete ties and the quarry site. MIT, Harvard and
U-Mass all located in the same state as the defendant have some clever civil
engineers and geologists who might be able to bring you up to snuff before
you create a video intended to influence a judge and jury about
defective railroad ties and the lives and property they put in jeopardy.

Have a nice day.

I have written my own reconstruction (or better alingment software). It runs
on a PC, but the actual matching is done on a Sun. However when you want to put
some time in it, it must be easy to convert it to Turbo or Microsoft C.

The idea is to find the optimal fit that minimizes the difference between
the greyvalues of both sections. I only correct for rotation and translation,
what limits the reconstruction to material with limited deformation. (plastic
sections).

For other section types : parafin, etc, Rotation and Translation only is not

Hello everyone,

I am new in the area of making video on a workstation, so I

2. Are there some books which treat the video subject on workstations ?
