Computer Graphics Resource Listing : WEEKLY POSTING [ PART 1/2 ]
===================================================
Last Change : 8 September 1992

[ Sorry for the latency, but we have a mass transit strike here in Greece...
  Another problem was the power outages due to general strikes - It took
  me 2 weeks to find the machines operating :-( . I hope to have a fast modem
  in a week.

 I split the list, because inews doesn't like articles larger than 63 KB :-(

 I think to split more intelligently the list, but I want to just get it out
 in this half-baked form. When I have more time, I'll do a more reasonable
 editing (If and when is another matter!)

 Merged with another HUGE list, I feel some trimming down is necessary,
 but I need some time 
 In general, more clean-up - in the end I'll do a spell check... -- nfotis ]

========================================================================

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 (FAQ)

+ John T. Grieggs <grieggs@jpl-devvax.jpl.nasa.gov> is the poster of the
+ official comp.graphics FAQ

This article is posted to comp.graphics 3-4 times a
month and is kept in the FTP sites (2 times/month I update these copies)
+ Note: I'll put only compressed copies, and because the Listing doesn't
+ change too much these days, I'll put a copy 1 time/month in the FTP places.

and
  gondwana.ecr.mu.oz.au, /incoming/graphics-resource-list.Z

The inria-graphlib mail server mirrors this posting (see under the
Subject 4: Mail servers )

+The Resource Listing is accesible through WAIS in the machine
+enuxva.eas.asu.edu (port 8000) under the name graphics-resources-list.
+It's got a digest-type line before every numbered item for purposes of
+indexing.

========================================================================

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.)

==========================================================================

2. Notes
--------
(Excerpted from the FAQ article by Jef Poskanzer.)

Please do *not* post or mail messages saying "I can't FTP, could
someone mail this to me?"  There are a number of automated mail servers
that will send you things like this in response to a message.

There are a number of sites that archive the Usenet sources newsgroups
and make them available via an email query system.  You send a message
to an automated server saying something like "send comp.sources.unix/fbm",
and a few hours or days later you get the file in the mail.

3. Computer graphics FTP site list, by Eric Haines
--------------------------------------------------

Ray Tracing related FTP sites (and maintainers), 9/8/92
compiled by Eric Haines, erich@eye.com
with help from Nick Fotis, nfotis@theseas.ntua.gr


Some highlights:
----------------

RayShade - a great ray tracer for workstations on up, but you can find
	a PC version, which requires FPU, plus Mac and Amiga versions.
Radiance - a ray tracer w/radiosity effects, a la Greg Ward (who wrote it).
	[ practically, demands UNIX, but some crazy people ported it
	to at least the Amiga -- nfotis ]
DKBtrace - another good ray tracer, from all reports; PCs, Mac II,
	Amiga, UNIX, VMS (last two with X11 previewer), etc.
ART - ray tracer with a good range of surface types, part of VORT package.
PoV - son of DKB trace, written by Compuservers. FTP places below
	(For more questions call Drew Wells --
	73767.1244@compuserve.com or Dave Buck -- david_buck@carleton.ca)
MTV,QRT,DBW - yet more ray tracers, some with interesting features.
prt, VM_pRAY - parallel ray tracers.

RTrace - Portugese ray tracer, does bicubic patches and other interesting stuff
	In the current version (7.3) there's also CSG support, 3D text, etc.
+	An MS-DOS version for use with DJGPP DOS extender (GO32) exists also.
VIVID2 - A shareware raytracer for PCs - binary only
	Now it's on version 2, packaged under the name vivid2.zip
	(286/287 binaries). Author: Stephen Coy (coy@ssc-vax.boeing.com).
	The 386/387 (NO src!) version is available to registered users (US$50)
	direct from the author.
#RAY4 - Steve Hollasch's 4-dimensional ray tracer - renders hyperspheres,
+	hypertetrahedra, hyperplanes, and hyperparallelepipeds (and there's
+	a separate real-time wireframe viewer written in GL - WIRE4 ) .

XDART - A distributed ray-tracer that runs under X11. There are server binaries
	ONLY for DECstations, SPARCs, HP Snakes (7x0 series) and NeXT.
	The clients are distributed as binaries and C source.
Inetray - A network version of Rayshade 4.0. Needs Sun RPC 4.0 or newer.
	Contact Andreas Thurnherr (ant@ips.id.ethz.ch) - FTP place below

#SIPP - Scan line z-buffer and Phong shading renderer.
+	Now uses the shadow buffer algorithm.
VOGLE - graphics learning environment (device portable).
VOGL - an SGI GL-like library based on VOGLE.
REND386 - A *fast* polygon renderer for Intel 386s and up. Version 2 on up.
	[ It's *NOT* a photorealistic, but a real-time renderer!]
VREND - Cornell's Volume Renderer, from Kartch/Devine/Caffey/Warren (FORTRAN).
RAD - An interactive radiosity package that runs on SGI machines with a
	Spaceball. Author: Guy Moreillon <moreillo@ligsg1.epfl.ch>
	FTP place below.

VISION-3D - Mac modeler, can output Radiance & Rayshade files.
IRIT - A CSG solid modeler, with support for freeform surfaces.
X3D - A wireframe viewer for X11.
SALEM - A GL-based package from Dobkin et al. for exploring mathematical
structures.
GEOMVIEW - A GL-based package for looking and interactively manipulating
3D objects, from Geometry Center at Minnesota.
3DV - 3-D wireframe graphics toolkit, with C source, 3dv objects, other stuff
	Look at major PC archives like wuarchive. One such file is 3DKIT1.ZIP

SPD - a set of procedural databases for testing ray tracers.
NFF - simplistic file format used by SPD.
OFF - another file format.
P3D - a lispy file format.
TDDD - Imagine (3D modeler) format, has converters for RayShade, NFF, OFF, etc.
	Also includes a nice postscript object displayer.  Some GREAT models.
TTDDDLIB - converts to/from TDDD/TTDDD, OFF, NFF, Rayshade 4.0, Imagine
	and vort 3d objects. Also outputs Framemaker MIF files and isometric
	views in Postscript. If you register (for $25), you get (besides other)
	a TeX PK font converter and a superquadric surfaces generator.
	Ask Glenn Lewis <glewis@pcocd2.intel.com>
	[ Note : you can spell TTDDDLIB as T3DLIB also ]

RT News - collections of articles on ray tracing.
RT bib - all known (by me) articles on ray tracing, in "refer" format.
RT abstracts - collection of abstracts of many many RT articles.

Utah Raster Toolkit - nice image manipulation tools.
PBMPLUS - a great package for image conversion and manipulation.
FBM - another set of image manipulation tools.
#Graphics Gems I-II-III - code from the ever so useful books.

(*) means site is an "official" distributor, so is most up to date.

ccu1.aukuni.ac.nz [130.216.1.5]:  ftp/mac/architec - *VISION-3D facet
	based modeller, can output RayShade files*.  Many other neat things
	for Macs.  Paul Bourke <pdbourke@ccu1.aukuni.ac.nz>

4. Mail servers and graphics-oriented BBSes
-------------------------------------------

Please check first with the FTP places above, with archie's help.
Don't overuse mail servers.

There are some troubles with wrong return addresses. Many of these
mail servers have a command like
   path a_valid_return_e-mail_address
to get a hint for sending back to you stuff.

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.

BITFTP
------
  For BITNET sites ONLY, there's BITFTP@PUCC.
  Send a one-line 'help' message to this address for more info.

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.

INRIA-GRAPHLIB
--------------
  Pierre Jancene and Sabine Coquillart launched the inria-graphlib mail
  server a few months ago.

    echo help | mail inria-graphlib@inria.fr

  will give you a quick summary of what inria-graphlib contains and 
  how to browse among its files.

    echo send contents | mail inria-graphlib@inria.fr

  will return the extended summary.

  As an other example :

    echo send cgrl from Misc | mail inria-graphlib@inria.fr

  will return the Computer Graphics Resource Listing mirrored from
  comp.graphics.

BBSes
-----
  There are many BBSes that store datafiles, etc.etc., but a guide to these
  is beyond the scope of this Listing (and the resources of the author!)
  If you can point to me Internet- or mail- accessible BBSes that carry
  interesting stuff, send me info!

  Studio Amiga is a 3D modelling and ray tracing specific BBS, (817) 467-3658.

==========================================================================

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@kpc.com).
[ The object archive server seems to be mothballed. In a future version,
 I'll remove the ref. to it -- nfotis ]

  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@cup.portal.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.

==========================================================================

8. Solids description formats
-----------------------------

a. EEC's ESPRIT project 322 CAD*I (CAD Interfaces) has developed a
  neutral file format for transfer of CAD data (curves, surfaces, and
  solid models between CAD systems and from CAD to CAA (Computer Aided
  Analysis) an CAM (Computer Aided Manufacturing)

b. IGES [v. 5.1 now] tries to define a standard to tranfer solid
  models - Brep and CSG. The current standard number is ANSI Y14.26M-1987
  For documentation, you might want to contact Nancy Flower at
  NCGA Technical Services and Standards, (USA) 703-698-9600

c. PDES/STEP : This slowly emerging standard tries to encompass not only
  the geometrical information, but also for things like FEM, etc.
  The main bodies besides this standard are NIST and DARPA. You can get
#  more information about PDES by sending mail to nptserver@cme.nist.gov
  and putting the line
	send index
  in the body (NOT the Subject:) area of the message.

  The people at Rutherford Appleton Lab.  are also working
  on STEP tools: they have an EXPRESS compiler and an Exchange file parser,
  both available in source form (and for free) for research purposes.
  Soon they will also have an EXPRESS-based database system.

  For the tools contact Mike Mead, Phone: +44 (0235) 44 6710 (FAX: x 5893),
  e-mail: mm@inf.rl.ac.uk or {...!}mcsun!uknet!rlinf!mm or
          mm%inf.rl.ac.uk@NSFnet-relay.ac.uk

9. Scene generators/geographical data/Maps/Data files
-----------------------------------------------------

DEMs (Digital Elevation Models)
-------------------------------
  DEMs (Digital Elevation Models) as well as other cartographic data
  [huge] is available from spectrum.xerox.com [192.70.225.78], /pub/map.

  Contact:
  Lee Moore -- Webster Research Center, Xerox Corp. --
  Voice: +1 (716) 422 2496
  Arpa, Internet:  Moore.Wbst128@Xerox.Com
[ Check also on ncgia.ucsb.edu (128.111.254.105), /pub/dems -- nfotis ]

  Many of these files are also available on CD-ROM selled by USGS:
  "1:2,000,000 scale  Digital Line Graph (DLG) Data". Contains datas
  for all 50 states. Price is about $28, call to or visit in offices
  in Menlo Park, in Reston, Virginia (800-USA-MAPS).

  The Data User Services Division of the Bureau of the Census also has
  data on CD-ROM (TSO standard format) that is derived from USGS
  1:100,000 map data. Call (301) 763-4100 for more info or they have
  a BBS at (301) 763-1568.


Fractal Landscape Generators
----------------------------

Public Domain:

  Many people have written fractal landscape generators. for example
  for the Mac some of these generators were written by
  pdbourke@ccu1.aukuni.ac.nz (Paul D. Bourke).
  Many of the programs are available from the FTP sites and mail
  archive servers. Check with Archie.

Commercial:

  Vista Pro 2.0 for the Amiga from Virtual Reality Labs -- list price
  is about $100. Their address is:
	VRL
	2341 Ganador court
	San Luis Obispo,
	CA 93401
	Telephone or FAX (805) 545-8515

  Scenery Animator (also for the Amiga) is of the same caliber with Vista Pro.
  Check with:
	Natural Graphics
	P.O. Box 1963
	Raklin, CA 95677
	Phone (916) 624-1436

  Don't forget to ask about companion programs and data disks/tapes.

  Addition: Vista Pro 2 has just ported to the PCs.


CIA World Map II
----------------
[  NOTE: this database is quite out of date, and not topologically structured.
  If you need a standard for world cartographic data, wait for the
  Digital Chart of the World. This 1:1M database has been produced from
  the Defense Mapping Agency's ONCs and will be available, together with
  searching and viewing software, on a number of CD-ROMs later this summer. ]

  Check into HANAUMA.STANFORD.EDU and UCSD.EDU (see ftp list above)
  The CIA database consists of coastlines, rivers and political boundaries
  in the form of line strokes. Also on hanauma.stanford.edu is a 720x360
  array of elevation data, containing one ieee floating point number for
  every half degree longitude and latitude.
 
  A program for decoding the database, mfil, can be found on the machine
  pi1.arc.umn.edu (137.66.130.11).
  There's another program, which reads a compressed CIA Data Bank file and
  builds a PHIGS hierachical structure. It uses a PHIGS extension known as
  polyline sets for performance, but you can use regular polylines. Ask
  Joe Stewart <joes@lpi.liant.com>.
  The raw data at Stanford require the vplot package to be able to view it.
  (was posted in comp.sources.unix). To be more exact, you'll have to
  compile just the libvplot routines, not the whole package.

NCAR data
---------
  NCAR has many types of terrain data, ranging from elevation datasets at
  various resolutions, to information about soil types, vegetation, etc.
  This data is not free -- they charge from $40 to $90 or more, depending
  on the data volume and media (exabyte tape, 3480 cartridge, 9-track tape,
  IBM PC floppy, and FTP transfer are all available).  Their data archive
  is mostly research oriented, not hobbyist oriented.  For more information,
  email to ilana@ncar.ucar.edu.

UNC data tapes with voxel data
--------------
  There are 2 "public domain" tapes with data for the comparison and
  testing of various volume rendering algorithms (mainly MRI and CT
  scans). These tapes are distributed by the SoftLab of UNC @ Chapel Hill.
  (softlab@cs.unc.edu)

+  The data sets (volume I and II) are also available via anonymous FTP from
+  omicron.cs.unc.edu [128.109.136.159] in pub/softlab/CHVRTD

NASA
----
  Many US agencies such as NASA publish CD-ROMs with many altimetry data
  from various space missions, eg. Viking for Mars, Magellan for Venus,
  etc. Especially for NASA, I would suggest to call the following
  address for more info:

     National Space Science Date Center
     Goddard Space Flight Center
     Greenbelt, Maryland 20771
     Telephone: (301) 286-6695
     Email address:  request@nssdca.gsfc.nasa.gov

  The data catalog (*not* the data itself) is available online.
  Internet users can telnet to nssdca.gsfc.nasa.gov (128.183.10.4) and log
  in as 'NODIS' (no password).

  You can also dial in at (301)-286-9000 (300, 1200, or 2400 baud, 8 bits,
  no parity, one stop). At the "Enter Number:" prompt, enter MD and
  carriage return. When the system responds "Call Complete," enter a few
  more carriage returns to get the "Username:" and log in as 'NODIS' (no
  password).

  NSSDCA is also an anonymous FTP site, but no comprehensive list of
  what's there is available at present.

Others
------
  Daily values of river discharge, streamflow, and daily weather data is
  available from EarthInfo, 5541 Central Ave., Boulder CO  80301.  These
  disks are expensive, around $500, but there are quantity discounts.

  is available from NGDC (National Geophysical Data Center), 325 Broadway,
  Boulder, CO  80303.  (303) 497-6958.

  EOSAT (at least in the US) now sells Landsat MSS data older than two years
  old for $200 per scene, and they have been talking about a similar deal
  for Landsat TM data. The MSS data are 4 bands, 80 meter resolution.

  Check out anonymous FTP to ftp.ncsa.uiuc.edu in
  UNIX/PolyView/alpha-shape for a tool that creates convex hulls
  alpha-shapes (a generalization of the convex hull) from 3D point sets.

  The GRIPS II (Gov. Raster Image Processing Software) CD-ROM
  is available from CD-ROM Inc. at 1-800-821-5245 for $49.
  Code for viewing ADRG (Arc Digitised Raster Graphics) files is
  available on the GRIPS II CD-ROM. The U.S. Army Engineer 
  Topographic Labs (Juan Perez) code is also available via FTP
  ( adrg.zip archive in  spectrum.xerox.com )

11. Background imagery/textures/datafiles
-----------------------------------------

a. Check in the FTP places that are mentioned in the FAQ.

b. Get a good 24-bit scanner, like Epson's. Suggested is an SCSI port for
  speed. Eric Haines had a suggestion in RT News, Volume 4, #3 :
  scan textures for wallpapers and floor coverings, etc. from doll
  house supplies.
  So you have a rather cheap way to scan patterns that don't have
  scaling troubles associated with real materials and scanning area..

c. Find some houses/books/magazines that carry photographic material.
  Educorp, 1-619-536-9999, sells CD-ROMS with various imagery - also
  a wide variety of stock art is available.
  Stock art from big-name stock art houses, such as Comstock,
  UNIPHOTO, and Metro Image Base, is available.  

  In Italy, there's a company called Belvedere that makes such books
  for the purpose of clipping their pages for inclusion in your
  graphics work. Their address is:
	Edition Belvedere Co. Ltd.,

12. Introduction to rendering algorithms
----------------------------------------

a. Ray-Tracing:

 I assume you have a general understanding of Computer Graphics. No? Then read
  some of the books that the FAQ contains. For Ray-Tracing, I would
  suggest:
   An Introduction to Ray Tracing, Andrew Glassner (ed.), Academic Press
     1989, ISBN 0-12-286160-4
  Note that I have not read the book, but I feel that you can't be wrong
  using his book. An errata list was posted in comp.graphics by Eric Haines
  (erich@eye.com)

There's a more consise reference also:

  Roman Kuchkuda , UNC @ Chapel Hill: "An Introduction to Ray Tracing", in
  "Theoretical Foundations for Computer Graphics and CAD", ed. R.A.E.Earnshaw,
  NATO AS, Vol. F-40., pp. 1039-1060. Printed by Springer-Verlag, 1988.

It contains code for a small, but fundamentally complete ray-tracer.

b. Z-buffer (depth-buffer)
  
A good reference is:

	_Procedural Elements for Computer Graphics_, David F. Rogers,
	McGraw-Hill, New York, 1985, pages 265-272 and 280-284.

13. Where can I find the geometric data for the:
------------------------------------------------

a. Teapot ?
-----------

I suggest you read the "Displays on Display" column of IEEE CG&A, Jan. '87.
It contains an account from Frank Crow of the whole story, plus the data
and a Pascal program to display them. The data were without structure ie.
polygons.

Jim Blinn had another article in "Jim Blinn's Corner" in the same magazine,
Sep. '87, in which he lists the teapot data as control points for Bezier
patches.

The OFF and SPD packages have these objects, so you're advised to get
them to avoid typing the data yourself.  The OFF data is triangles at
a specific resolution (around 8x8[x4 triangles] meshing per patch).
The SPD package provides the spline patch descriptions and performs a
tessellation at any specified resolution.

b. Space Shuttle ?
------------------

Tolis Lerios <tolis@nova.stanford.edu> has built a list of Space Shuttle
datafiles. Here's a summary (From his sci.space list):

model1:
A modified version of the newsgroup model (model2)

406 vertices (296 useful, i.e. referred to in the polygon descriptions.)
389 polygons (233 3-vertex, 146 4-vertex, 7 5-vertex, 3 6-vertex).
Payload doors non-existent.
Units: unknown.

Simon Marshall (S.Marshall@sequent.cc.hull.ac.uk) has a copy. He
said there is no proprietary information associated with it.

model2:
The newsgroup model, in OFF format. You can find it in

gondwana.ecr.mu.oz.au , file pub/off/objects/shuttle.geo
hanauma.stanford.edu ,  /pub/graphics/Comp.graphics/objects/shuttle.data

model3:
The triangles' model.

This model is stored in several files, each defining portions of the model.

Greg Henderson (henders@infonode.ingr.com) has a copy.  He did
not mention any restriction on the model's distribution.

model4:
The NASA model.

The file starts off with a header line containing three real numbers,
defining the offsets used by Lockheed in their simulations:

<x offset> <y offset> <z offset>

From then on, the file consists of a sequence of polygon descriptions

3473 vertices.
2748 polygons (407 3-vertex, 2268 4-vertex, 33 5-vertex, 14 6-vertex,
 10 7-vertex, 8 8-vertex, 8 12-vertex, 2 13-vertex, 2 15-vertex,
 17 16-vertex, 2 17-vertex, 2 18-vertex, 3 19-vertex, 8 24-vertex).
Payload doors closed.
Units: inches.

Jon Berndt (jon@l14h11.jsc.nasa.gov) seems to be responsible for the model
Proprietary info: unknown

model5:
The old shuttle model.

The file consists of a sequence of polygon descriptions.

104 vertices.
452 polygons (11 3-vertex, 41 4-vertex).
Payload doors open.
Units: meters.

We have been using this model at STAR Labs, Stanford University, for
some years now. Contact me (tolis@nova.stanford.edu) or my supervisor
Scott Williams (scott@star5.stanford.edu) if you want a copy.

14. Plotting packages
---------------------

Gnuplot 3.2
-----------
  It is one of the best 2- and 3-D plotting packages, with
  online help.It's a command-line driven interactive function plotting utility
  for UNIX, MSDOS, and VMS platforms.  Freely distributed, it supports many
  terminals, plotters, and printers and is easily extensible to include
  new devices. It was posted to comp.sources.misc in version 3.0, plus
  2 patches.
  You can practically find it everywhere.

#Xvgr and Xmgr (ACE/gr)
-----------------------
+  Xmgr is an XY-plotting tool for UNIX workstations using 
+  X or OpenWindows. There is an XView version called xvgr for 
+  Suns. Collectively, these 2 tools are known as ACE/gr.
+  Compiling xmgr requires the Motif toolkit version 1.1
+  and X11R4 - xmgr will not compile under X11R3/Motif 1.0x.
+
+  Check at amb4.ese.ogi.edu [129.95.20.76] in CCALMR/pub/acegr/xmgr-2.09.tar.Z
+
+  Comments, suggestions, bug reports to Paul J Turner
+  <pturner@amb4.ese.ogi.edu> (if mail fails, try pturner@ese.ogi.edu).
+  Due to time constraints, replies will be few and far between.

Robot
-----
  Release 0.44 : 2-D and limited 3-D. Based on XView 3, written
  in C / Fortran (so you need a Fortran compiler or the f2c translator).
  Mainly tested on Sun4, less on DECstations. Check at
  astrod.astro.psu.edu (128.118.147.28),  pub/astrod.

VG plotting library
-------------------
  This is a library of Fortran callable routines at sunspot.ceee.nist.gov
  [129.6.64.151]

Xgobi
-----
  It's being developed at Bellcore, and its speciality are
  multidimensional data sets analysis and exploration. You can call it
  from the S language also, and it works as an X11 client using the Athena
  widget set (or with an ASCII terminal). It's distributed free of charge
  from STATLIB at CMU.
  To get it via e-mail, send email to statlib@temper.stat.cmu.edu and
  in the body area of the message, put the line

  send xgobi from general

  If you want to pick it via ftp, connect to lib.stat.cmu.edu. Log in as
  "statlib" and use your e-mail address as your password. Then type

  cd general
  mget xgobi.*

  Warning: It's about 2 MB sources + large Postscript manual. Read the
  relevant README to decide whether you need it or not.

PGPLOT
------
  Runs on VAX/VMS and supposedly on UNIX. Available at
  deimos.caltech.edu [131.215.139.14].

XMGR (also known as ACE/gr)
---------------------------
  Xy plotting package which runs under X windows.
  It will display a data set and calculate its FFT. It was written by Paul
  Turner and is available via anonymous ftp on amb4.ese.ogi.edu [129.95.20.76]
  in pub/acegr

GGRAPH
------
  Host shorty.cs.wisc.edu [128.105.2.8] : /pub/ggraph.tar.Z
  Unknown more details.

epiGRAPH
--------
  For PCs. Call dvj@lab2.phys.lgu.spb.su (Vladimir J. Dmitriev) for details.
  You can get the program demo or (and) play version, if sent 10 $ to
