3-D OBJECTS IN THE INTERNET
===========================
(See also last item for a phone/modem site)
Specifications for graphic formats can be found in:
zamenhof.cs.rice.edu 128.42.1.75 in pub/graphics.formats
The following info has been excerpted from the Computer Graphics Resource
Listing (version of 10 June 1992), compiled by Nikolaos (Nick) C. Fotis
(nfotis@theseas.ntua.gr).
========================================================================
This is mainly a guide for computer graphics software.
I would suggest reading the Comp. Graphics FAQ for image analysis stuff.
It's entitled:
(date) comp.graphics frequently asked questions.
This article is posted to comp.graphics 3-4 times a
month and is kept in the FTP sites
cgcr.gsu.edu, tmp/graphics-resource-list
nic.funet.fi, pub/graphics/misc/graphics-resource-list
weedeater.math.yale.edu, pub/incoming/graphics-resource-list
and
gondwana.ecr.mu.oz.au, /incoming/graphics-resource-list
I have included my comments within braces '[' and ']'.

1. ARCHIE
---------
The Archie is a service system to locate FTP places for
requested files. It's appreciated that you will use Archie
before asking help in the newsgroups.
Archie servers:
archie.mcgill.ca or 132.206.2.3 (Canada)
archie.funet.fi or 128.214.6.100 (Finland/Eur.)
archie.au or 139.130.4.6 (Aussie/NZ)
cs.huji.ac.il or 132.65.6.5 (Israel)
archie.doc.ic.ac.uk or 146.169.3.7 (UK/Ireland)
archie.sura.net or 128.167.254.179 (USA [MD])
archie.unl.edu (password: archie1) (USA [NE])
archie.ans.net or 147.225.1.2 (USA [NY])
archie.rutgers.edu or 128.6.18.15 (USA [NJ])
Connect to Archie server with telnet and type "archie" as username.
To get help type 'help'.
You can get 'xarchie' or 'archie', which are clients that call Archie
without the burden of a telnet session.
'Xarchie' is on the X11.R5 contrib tape, and 'archie' on comp.sources.misc,
vol. 27.
To get information on how to use Archie via e-mail, send mail with
subject "help" to "archie" account at any of above sites.
(Note to Janet/PSS users -- the United Kingdom archie site is
accessible on the Janet host doc.ic.ac.uk [000005102000].
Connect to it and specify "archie" as the host name and "archie" as
the username.)

7. Scene description languages
------------------------------
NFF
---
Neutral file format , by Eric Haines. Very simple, there are some
procedural database generators in the SPD package, and many objects
floating in various FTP sites. There's also a previewer written in
HP Starbase from E.Haines. Also there's one written in VOGLE, so you can
use any of the devices VOGLE can output on.
(Check in sites carrying VOGLE, like gondwana.ecr.mu.oz.au)
OFF
---
Object file format, from DEC's Randy Rost (rost@granite.dec.com).
Available also through their mail server. To obtain help about using this
service, send a message with a "Subject:" line containing only the word
"help" and a null message body to: object-archive-server@decwrl.dec.com.
[For FTP places to get it, see in the relevant place]. There's an OFF
previewer for SGI 4D machines, called off-preview in
godzilla.cgl.rmit.oz.au . There are previewers for xview and sunview,
also on gondwana.
TDDD
----
It's a library of 3D objects with translators to/from OFF, NFF,
Rayshade, Imagine or vort objects.
Edited copy of the announcement follows (from Raytracing News, V4,#3):
New Library of 3D Objects Available via FTP, by Steve Worley
(worley@updike.sri.com)
I have assembled a set of over 150 3D objects in a binary format
called TDDD. These objects range from human figures to airplanes,
from semi-trucks to lampposts. These objects are all freely
distributable, and most have READMEs that describe them.
In order to convert these objects to a human-readable format, a file
with the specification of TDDD is included in the directory with the
objects. There is also a shareware system called TTDDDLIB (officially
on hubcap.clemson.edu) that will convert (ala PBM+) to/from various
object formats : Imagine TTDDD (extension of TDDD?), OFF, NFF,
Rayshade 4.0, or vort. Source included for Amiga/Unix as executables
for the Amiga. Also outputs Framemaker MIF files and isometric views
in Postscript.
P3D
---
From Pittsburgh Supercomputing Center. The P3D uses lisp with slight
extensions to store three-dimensional models. A simple lisp
interpreter is included with the P3D release, so there is no need to
have access to any vendor's lisp to run this software.
The mouse-driven user interfaces for Motif, Open Look, and Silicon
Graphics GL, and the DrawP3D subroutine library for generating P3D
without ever looking at the underlying Lisp.
The P3D software currently supports nine renderers. They are:
Painter - Painter's Algorithm, Dore, Silicon Graphics Inc. GL language,
Generic Phigs, Sun Phigs+, DEC Phigs+, Rayshade, ART ray tracer (from
VORT package) and Pixar RenderMan.
The code is available via anonymous FTP from the machines
ftp.psc.edu, directory pub/p3d, and nic.funet.fi, directory
pub/graphics/programs/p3d.
RenderMan
---------
Pixar's RenderMan is not free - call Pixar for details.

4. Mail servers
---------------
a. DEC's FTPMAIL
Send a one-line message to ftpmail@decwrl.dec.com WITHOUT a Subject: field,
and having a line containing the word 'help'.
You should get back a message detailing the relevant procedures you
must follow in order to get the files you want.
Note that the "reply" or "answer" command in your mailer will not work
for this message or any other mail you receive from FTPMAIL. To send
requests to FTPMAIL, send an original mail message, not a reply.
Complaints should be sent to the ftpmail-request@uucp-gw-2.pa.dec.com
address rather than to postmaster, since DECWRL's postmaster is not
responsible for fixing ftpmail problems.
c. Lightwave 3D mail based file-server
A mail based file server for 3D objects, 24bit JPEG images, GIF images
and image maps is now online for all those with Internet mail access.
The server is the official archive site for the Lightwave 3D mail-list.
The server resides on a BBS called "The Graphics BBS". The BBS is
operational 24 hours a day 7 days a week at the phone number of +1
908/469-0049. It utilizes a Hayes V-Series 9600 V.42 modem. (soon to
upgrade to a V.32 modem)
If you would like to submit objects, scenes or images to the server,
please pack, uuencode and then mail the files to the address:
server@bobsbox.rent.com.
For information on obtaining files from the server send a mail message
to the address file-server@graphics.rent.com with the following in
the body of the message:
HELP
/DIR
And a help file describing how to use the server and a complete
directory listing will be sent to you via mail.
