1.	486SX is somewhat faster that 386DX.
2.	It has fewer bugs.
3.	It has internal cache.
4.	It is most likely more expensive.

Possibly 8086 compilers will work?  Anyway, the compiler guys will
know if it makes a difference.

A company called SCI made 80186-based PCs in the early days of the
original PC and the XT.  Around that time, not all PCs were totally
compatible (e.g., Tandy had a problem with one; DEC had the Rainbow;
most others who were not compatible went under).

There is no such thing as a 386DX2.  Intel is never going to clock-double the 386.
Another company probably will have a plug-compatible chip for the 386 that is faster,
but currently these things use more power and generate more heat - so there is a problem
with plugging them into just any motherboard.

Organization: The Jackson Laboratory
Date: Fri, 9 Oct 92 19:40:53 GMT

    We have a prototype system that we have been using for efforts in 
automated mouse chromosome analysis. I need to replace some of the equipment,
as I borrowed and begged things from other projects, and I need to return
them. Images under a Zeiss light microscope are captured by a Dage/MTI 66 
Series Camera. The camera output is RS-330 and is feed into an Imaging
Technology Series 150 System which in turn is connected via VME bus to a
Sun-3/110C system. The Imaging Technology System is used only to capture the 
image into its frame buffer, and make this available to the Sun computer in a 
512 x 512 x 256 grey image. The enhancement, boundary identification, object 
recognition and classification are/will be software controlled on the Sun 
computer. Software is wrappered by the Khoros system (John Rasure et al. from 
U. New Mexico) and is C and X based (e.g., portable).

    The microscope and the camera stay. I have to replace the imaging system 
and the computer. One solution is to obtain an Sbus based Imaging Technology 
System and a Sun Sparc. But there might be better configurations. The problem 
reduces to finding a good, and economical, board/imaging system to combine
with a computer. I am partial to Sun and Silicon Graphics systems. 

    Any advice, suggestions, pointers, etc.  would be appreciated. Please 
email replies directly. Thank you.

Hopefully, someone out there in graphics-land knows what's happening.

I have a standard PC with a cheapy SVGA+ monitor (they call it ULTRA VGA)
and a Trident graphics card with .5 meg of on-board memory.  Both the
board and the monitor support VGA and SVGA.  When I run VGA applications,
everything is fine.  When I run SVGA, whether using Trident's drivers or
the ones that came with Win3.1, the monitor's screen image shrinks.  It
looks like a screen within a screen -- sorta like the size of a Mac.

Since I want full-screen SVGA, I'm willing to replace the part causing
this behavior -- but *what* part is causing it to do that.  Anyone know?

We really really really would appreciate this information.
Thank You.

Subject: Info Needed on Scanning Noisy Line Drawings
Organization: SCTC
Date: Sat, 10 Oct 1992 19:08:16 GMT

Apologies for what must be a newbie question, but here goes:

I have a substantial inventory of shapes which I wish to convert from
line drawings on paper to digital models.  The shapes are renderings
of boat hulls consisting, in effect, of horizontal and vertical
cross-sections at regular intervals.  The drawings are from old
magazines, some copied off of microfilm, are quite "noisy," and in
some cases rather small (4x8 inches or so).

I am looking for a tool which will enable me to capture the
approximate (x,y,z) coordinates of selected points without spending
many hours with a ruler and a pair of calipers.

This appears to be possible if I could scan in a drawing and select
the origin of a virtual set of coordinates and a scale.  I would then
be able to click on points of interest and have the coordinate values
captured.  The result would be a set of (x,y), (x,z), and (y,z)
coordinate points for later processing. The input tool does not have
to resolve mismatches between the various projections, just capture
the raw data.  A zoom capability, with corresponding adjustment in
scale, is required because of the small scale of some of the drawings.

Does anyone have any hints or pointers to existing tools, or toolkits
that would enable such a data capture program to be readily
constructed?  It seems to me that this is a common problem, and
building a tool from the mouse driver up would  duplicate a lot of
somebody else's effort.  Stuff that runs on a 386/486 clone preferred
but not required.

Gplot never uses hardware fonts, it always strokes the text out
(to insure that the picture looks the same everywhere).
MacGplot should create a Pict file with text represented by line segments.
Are you seeing something else?

The easy way to change the font on a cgm file is to use gplot to create a
clear text version of the cgmfile, search through the clear text output for
font info, and change it.  Gplot can then convert the clear text cgm back to
a binary encoding if you need to save space/load time, or just use your
editted (clear text) version.

What you are referring to is texture mapping.  Finding a good reference is
very difficult.  The best reference I've seen to date is a book called
Digital Image Warping by George Wolberg from the IEEE Computer Society press.
It's not the last word because some of the algorithms appear to be flawed with
inaccuracies, but it gives some good ideas.  If you can find any papers from
a guy by the name of Paul Heckbert, get them.  I think works for or used to
work for Pixar.  Unfortunately, it's just not well documented in most graphic
books (3d) you will find at a good book store.  If you find some code samples
I would be interested in your source since this is a personal project for
myself as well.

Dear All:

	I wonder if any of you could help:

	I'm writing radiosity code on an HP 9000/730 workstation with
Motif 1.1 running on it.  My Problem: I'm doing progressive refinement
(hemicube) radiosity, so after each shoot I have a frame buffer which
contains the image I want (24bit colour); I want to open a window for
my first image and load the subsequent ones in as I evaluate them - so
that the image "improves" before my eyes.

	At present I just write it to a file and use xloadimage,
getx11, xv or xwud to display the latest piccy every time I feel like
it ! This is most unsatisfactory as I've constantly got to open a new
window or click a mouse button to get my latest piccy.  Can anyone out
there give me some heavy clues as to how I can go about doing what I
want without attending a 3 year course on X ???

	To date, I've always used PHIGS PLUS for the display part - this
is why I'm pretty clueless about it. I'd like something like:

	XOpenDisplay(window);
	while ( !done ) {
	    get_new_piccy ( &latest_pic );
	    send_piccy ( window, latest_pic );
	}
	Tidy_Up;

	Does anyone know how to run xv, xloadimage or getx11 so that
it puts the image in an already-open window, rather than always
opening a new one ?

	_Any_ help much appreciated.

	PS File format is not a problem; I can put my data into lots
of pretty file formats.
	PPS Replies by email must appreciated (as opposed to UseNet) I'd
be happy to post a summary.

	Thanks,

	Neil
