Date: Mon, 31 Aug 1992 16:05:34 GMT

I wish to send uuencoded .PCX 8-bit grayscale and 24-bit colour images 
to overseas FTP/E-Mail sites. In order to keep the encoding and 
decoding standardized, I'm looking for an FTP source or the E-mail 
address of: Theodore A. Kaldis who's copyright version 1.2 of QUUNCD -
uuencode/uudecode for DOS systems is available for free distribution.
Since this may be of general interest to this group, you may reply on 
the network or you may reply to me directly at: haggas@kean.ucs.mun.ca

I also have an unresolved problem in transferring images with the
"send" or "put" command in FTP, using the VAX/ULTIX system. These are
images that were transferred to the VAX account with mskerm(dos).
On using FTP to "send" to another VAX account, the record length was
converted from variable length, max. 510 bytes to fixed length, 512 
bytes.

The interest or response of people on the network will be greatly 
appreciated.

Hi!
I have a 486 with a SVGA, and I am writing a graphic program in C.
I use a Borland C++ compiler, but it allows me to use only standard VGA
resolutions (640x??). How can I fully exploit my 1024x768 - 256 color card?

Please e-mail me the answer, since I can read this newsgroup only once in a

Thanks in advance for the help.

You need a gridding program to generate a regular grid from the from
the scattered data.  There are many algorithms to do this such as
inverse distance weighting, triangle-based methods, radial basis
functions, and natural neighbour interpolation.  For a short survey of
such methods

Come on, ease up. This CD-ROM stuff is an experiment. Let's see what information
we get from it. You aren't losing out on any information or research because you
get the proceedings anyway, regardless of attending the conference. If the
proceedings are available in hardcopy, it will be interesting to note if the CD-ROM
will be used much at all. Since I think this is a valid question, a cheaper way to
find out the answer is to just give the CD to conference attendees, instead of
giving it to everyone and their brother. If the CD-ROM is a big hit and promotes
more research and knowledge, and they distribute the same way next time, then you
can gripe.

IMHO,
William

Hello out there in NewsLand! Does anyone know of any good books on

Also, if you know of any good sources for art books in general, it

Evans & Sutherland makes an 8 knob dial box (each with an eight
character LED display above each dial).  We support the dial box
through the X Input Extension (which is what the AVS port uses).  I'm
not sure what the model/number is, but you should be able to find out
by calling our 800 number: 1-800-367-7460.

	I'm currently doing some work with a Radius Multiview 24 bit video

running an orchid 1280 1024x768x8bits.  Winmarks off the pc lab benchmark
are 3,175,000.  Comparison #s are: ATI-XL 800x600x8bit 1,700,000, Paradise
accelerator 800x600x8bit 5,100,000.  This all on a dell 386/33, win3.1, etc.

	I am running the radius card on an NEC 4FG monitor.  Its not the
speed I'd _like_ to have but then the cpu speed on this machine is rather
slow.  In a 450 things would be rather pleasant.

Without a doubt, Foley, van Dam, Feiner, and Hughes, _Computer

is the book you need.

The Rogers book is pretty good, too -- I'll probably pick it up

Here's an area formula that so neat I thought I'd post it in addition
to sending it to Matt.  It probably extends to 3D as well, but right now
I don't have time to test that theory.

Hi,
how do the 24X win3.1 drivers work ?
I heard very bad news about them.

BTW, I have a Genoa 7900 true color SVGA board and it works very fast
under win3.1 and its 640x480 true color mode, for instance with
photostyler !

Does anyone have source code for TC 2.0 that will display a gif given a
filename, and position? I tried using GIFLIB12 from simtel but had a
real hard time with it. Would appreciate any help, or hints on where to
find such code.

Thanks in advance,

Dave
