IRIS Explorer
-------------
  It's an application creation system developed by Silicon
  Graphics that provides visualisation and analysis functionality for
  computational scientists, engineers and other scientists. The Explorer
  GUI allows users to build custom applications without having to write
  any, or a minimal amount of, traditonal code. Also, existing code can
  be easily integrated into the Explorer environment. Explorer currently
  is available now on SGI and Cray machines, but will become available on
  other platforms in time. [ Bundled with every new SGI machine, as far as
  I know]

  See comp.graphics.explorer or comp.sys.sgi for discussion of the package.

  There are also two FTP servers for related stuff, modules etc.:

  ftp.epcc.ed.ac.uk [129.215.56.29]
  swedishchef.lerc.nasa.gov [139.88.54.33] - mirror of the UK site

apE
---

WIT
---
  In a nutshell it's a package of the same genre as AVS,Explorer,etc.
  It seems more a image processing system than a generic SciVi system (IMHO)
  Major elements are:

  - a visual programming language, which automatically exploits the inherent
        parallelism
  - a code generator which converts the graph to a standalone program

  Iconified libraries present a rich set of point, filter, io, transform,
  morphological, segmentation, and measurement operations.
  A flow library allows graphs to employ broadcast, merge,
  synchronization, conditional, and sequencing control strategies.

  Users can easily extend WIT by defining new C functions, data types,
  and servers to access specialized hardware.

  They are currently sending out free 3.5" demo disks suitable for Sun
  Sparcstation floppy drives to anyone interested in trying out the
  software (and they are thinking about putting a copy of the demo for
  FTP).
  Or you can try the Catalyst CDware program as trial software;
  Demo version on Sun CDware 4.

  WIT supports Sun3, Sun4, vxWorks by Wind River Systems,
  and Datacube (MaxVideo-20 hardware) platforms.

  Pricing: WIT for Sparc, one yr. free upgrades, 30 days
  technical support....................$5000 US

  Academic institutions: discounts available

IDL/PV-WAVE
-----------
  "The IDL/PV-WAVE software package is what I currently use .
  I/O is very simple (a major plus!!) & most of my
  programming is very short & sweet.  Numerous output formats are
  available.  there are certainly some minuses & it does require
  "programming".  I use the command line version, though the "point &
  click" version is available...I have some acquaintances who use it on
  the Mac (I think via Mac-X).  Basically, there are a lot of built-in
  functions, though some manipulation is required.  IDL/PV-WAVE is able to
  work with any type of imagery. IDL runs on a unix system"

IDL/SIPS
--------
  "A lot of people are using IDL with a package called SIPS. This was
  developed at the University of Colorado (Boulder) by some people working
  for Alex Goetz.  You might try contacting them if you already have IDL
  or would be willing to buy it.  It's a few thousand dollars (American) I
  expect for IDL and the other should be free.  Those are the general
  purpose packages I've heard of, besides what TerraMar has.
  SIPS _was_ written for AVIRIS imagery.  I'm not sure how general purpose
  it is.  You would have to contact Goetz or one of his people and ask.  I
  have another piece of software (PCW) that does PC and Walsh
  transformations with pseudocoloring and clustering and limited image
  modification (you can compute an image using selected components).  I've
  used it on 70 megabyte AVIRIS images without problems, but for the best
  speed you need an external DSP card.  It will work without it, but large
  images take quite a while (50-70 times as long) to process.  That's a
  freebie if you want it"

  "My  favorite is IDL (Interactive Data Language) from Research Systems,
  Inc.  IDL is in my opinion, much better and infinitely easier. Its
  programming language is very strong and easy -- very Pascal-like. It
  handles the number-crunching very well, also. Personally, I like doing
  the number-crunching with IDL on the VAX (or Mathematica, Igor, or even
  Excel on the Mac if it's not too hairy), then bringing it over to NIH
  Image for the imaging part. I have yet to encounter any situation which
  that combination couldn't handle, and the speed and ease of use
  (compared to IRAF) was incredible. By the way, it's mostly astronomical
  image processing which I've been doing. This means image enhancement,
  cleaning up bad lines/pixels, and some other traditional image
  processing routines. Then, for example, taking a graph of intensity
  versus position along a line I choose with the mouse, then doing a curve
  fit to that line (which I might do like in KaleidaGraph.) "

[ For IDL call Research Systems , for PV-WAVE call Precision Visuals and
 for SIPS call University of Colorado @ Boulder . From what I can
 understand, you can get packaged programs from Research Systems, though

18. Molecular visualization stuff
---------------------------------

[ Based on a list from cristy@dupont.com < Cristy > , which asked for
 systems for displaying Molecular Dynamics, MD for short ]

Flex
----
  It is a public domain package written by Michael Pique, at The Scripps
  Research Institute, La Jolla, CA. Flex is stored as a compressed,
  tar'ed archive (about 3.4MB) at perutz.scripps.edu [137.131.152.27], in
  pub/flex. It displays molecular models and MD trajectories.

MacMolecule
-----------
  (for Macintosh). I searched with Archie, and the most
  promising place is sumex-aim.stanford.edu (info-mac/app, and
  info-mac/art/qt for a demo)

MD-DISPLAY
----------
  Runs on SGI machines. Call Terry Lybrand (lybrand@milton.u.washington.edu).


XtalView
--------
  It is a crystallography package that does visualize molecules and much more.
  It uses the XView toolkit.
  Call Duncan McRee <dem@scripps.edu>

landman@hal.physics.wayne.edu:
-----------------------------
  I am writing my own visualization code right now.  I look at MD output
  (a specific format, easy to alter for the subroutine) on PC's.  My
  program has hooks into GKS.  If your friend has access to Phigs for X
  (PEX) and fortran bindings, I would be happy to share my evolving code
  (free of charge).  Right now it can display supercells of up to 65
  atoms (easy to change), and up to 100 time steps, drawing nearest
  neighbor bonds between 2 defining nn radii.  It works acceptably fast
  on a 10Mhz 286.

icsg0001@caesar.cs.montana.edu:
------------------------------
  I did a project on Molecular Visualization for my Master's Thesis, using
  UNIX/X11/Motif which generates a simple point and space-filling model.

KGNGRAF
-------

KGNGRAF is part of MOTECC-91. Look on malena.crs4.it (156.148.7.12),
in pub/motecc.

motecc.info.txt          Information about MOTECC-91 in plain ascii format.

ditolla@itnsg1.cineca.it:
------------------------
  I'm working on molecular dynamic too.  A friend of mine and I have

  developed a program to display an MD run dynamically on Silicon
  Graphics.  We are working to improve it, but it doesn't work under X,
  we are using the graphi. lib. of the Silicon Gr. because they are much
  faster then X.  When we'll end it we'll post on the news info about
  where to get it with ftp. (Will be free software).

XBall V2.0
----------
  Written by David Nedde. Call daven@maxine.wpi.edu.

XMol
----
  An X Window System program that uses OSF/Motif  for  the
  display and  analysis  of  molecular  model data.  Data from several
  common file formats can be read and written; current formats include:
  Alchemy, CHEMLAB-II, Gaussian, MOLSIM, MOPAC, PDB, and MSCI's XYZ
  format (which has been designed  for  simplicity  in  translating to
  and from other formats). XMol also allows for conversion between
  several of these formats.
  Xmol is available at ftp.msc.edu. Read pub/xmol/README for
  further details.

INSIGHT II
----------
  from BIOSYM Technologies Inc.

SCARECROW
---------
  The program has been published in J. Molecular Graphics 10
  (1992) 33. The program can analyze and display CHARMM, DISCOVER, YASP
  and MUMOD trajectories. The program package contains also software for
  the generation of probe surfaces, proton affinity
  surfaces and molecular orbitals from an extended Huckel program.
  It works on Silicon Graphics machines.
  Contact Leif Laaksonen <Leif.Laaksonen@csc.fi or laaksone@csc.fi>

[ I would also suggest looking at least in SGI's Applications Directory.
 It contains many more packages - nfotis ]

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

19. GIS (Geographical Information Systems software)
---------------------------------------------------

GRASS
-----
  (Geographic Resource Analysis Support System) of the US Army
  Construction Engineering Research Lab (CERL). It is a popular geographic and
  remote sensing image processing package. Many may think of GRASS as a
  Geographic Information System rather than an Image Processing package,
  although it is reported to have significant image processing
  capabilities.

  Feature Descriptions

  I use GRASS  because it's public domain and can be obtained through the
  internet for free.  GRASS runs in Unix and is written in C.  The source
  code can be obtained through an anonymous ftp from the Office of Grass
  Integration.  You then compile the source code for your machine, using
  scripts provided with GRASS.  I would recommend GRASS for someone who
  already has a workstation and is on a limited budget. GRASS is not very
  user-friendly, compared to Macintosh software." A first review  of
  overview documentation indicates that it looks useful and has some pixel
  resampling functions not in other packages plus good general purpose
  image enhancement routines (fft). Kelly Maurice at Vexcel Corp. in
  Boulder, CO is a primary user of GRASS .  This gentleman has used the
  GRASS software and developed multi-spectral (238 bands ??) volumetric
  rendering, full color, on Suns and Stardents. It was a really effective
  interface.  Vexcel Corp. currently has a contract to map part of Venus
  and convert the Magellan radar data into contour maps. You can call them
  at (303) 444-0094 or email care of greg@vexcel.com 192.92.90.68

  Host Configuration Requirements

  If you are willing to run A/UX you could install GRASS   on a Macintosh
  which has significant image analysis and import capabilities for
  satellite data. GRASS  is public-domain, and can run on a high-end PC
  under UNIX. It is raster-based, has some image-processing capability,
  and can display vector data (but analysis must be done in the raster
  environment). I have used GRASS V.3 on a SUN workstation and found it
  easy to use. It is best, of course, for data that are well represented
  in raster (grid-cell) form.

  Availability

  CERL's Office of Grass Integration (OGI)  maintains an ftp server:
  moon.cecer.army.mil (129.229.20.254).

  Mail regarding this site should be addressed to
  grass-ftp-admin@moon.cecer.army.mil.

  This location will be the new "canonical" source for GRASS software, as
  well as bug fixes, contributed sources, documentation, and other files.
  This FTP server also supports dynamic compression and uncompression and
  "tar" archiving of files.  A feature attraction of the server is John
  Parks' GRASS tutorial.  Because the manual is still in beta-test stage,
  John requests that people only acquire it if they are willing to review
  it and mail him comments/corrections. The OGI is not currently
  maintaining this document, so all correspondence about it should be
  directed to grassx@tang.uark.edu

  Support

  Listserv mailing lists:

  grassu-list@amber.cecer.army.mil (for GRASS users; application-level
  questions, support concerns, miscellaneous questions, etc) Send
  subscribe commands to grassu-request@amber.cecer.army.mil.

  grassp-list@amber.cecer.army.mil (for GRASS programmers; system-level
  questions and tips, tricks, and techniques of design and implementation
  of GRASS applications) Send subscribe commands to
  grassp-request@amber.cecer.army.mil.

  Both lists are maintained by the Office of Grass Integration (subset of
  the Army Corps of Engineers Construction Engineering Research Lab in
  Champaign, IL). The OGI is providing the lists as a service to the
  community; while OGI and CERL employees will participate in the lists,
  we can make no claim as to content or veracity of messages that pass
  through the list.  If you have questions, problems, or comments, send
  E-mail to lists-owner@amber.cecer.army.mil and a human will respond.

Microstation Imager
-------------------
  Intergraph (based in Huntsville Alabama) sells a wide range of GIS
  software/hardware. Microstation is a base  graphics package that Imager
  sits on top of. Imager is basically an  image processing package with a
  heavy GIS/remote sensing flavor.

  Feature Description

  Basic geometry manipulations: flip, mirror, rotate, generalized affine.
  Rectification: Affine, 2nd, 3rd, 4th and 5th order models as well as a
  projective model (warp an image to a vector map or to another image).
  RGB to IHS and IHS to RGB conversion.  Principal component analysis.
  Classification: K-means and isodata.  Fourier Xforms: Forward, filtering
  and reverse.  Filters: High pass, low pass, edge enhancing, median,
  generic.  Complex Histogram/Contrast control.  Layer Controller: manages
  up to 64 images at a time -- user can extract single bands from a 3 band
  image or create color images by combining various individual bands, etc.

  The package is designed for a remote sensing application (it can handle
  VERY LARGE images) and there is all kinds of other software available
  for GIS applications.
  Host Configuration Requirements

  It runs on Intergraph Workstations (a Unix machine similar to a Sun)
  though there  were rumors (there are always rumors) that the software
  would be  ported to PC and possibly a Sun environment.

PCI
---
  A company called PCI, Inc., out of Richmond Hill, Ontario, Canada, makes
  an array of software utilities for processing, manipulation, and use of
  remote sensing data in eight or ten different "industry standard"
  formats: LGSOWG, BSQ, LANDSAT, and a couple of others whose titles I
  forget.  The software is available in versions for MS-DOS, Unix
  workstations (among them HP, Sun, and IBM), and VMS, and quite possibly
  other platforms by now.  I use the VMS version.

  The "PCI software" consists of several classes/groups/packages of
  utilities, grouped by function but all operating on a common "PCI
  database" disk file.  The "Tape I/O" package is a set of utility
  programs which read from the various remote-sensing industry tape
  formats INTO, or write those formats out FROM, the "PCI database" file;
  this is the only package I use or know much about.  Other packages can
  display data from the PCI database to one or another of several
  PCI-supported third-party color displays, output numeric or bitmap
  representation of image data to an attached printer, e.g. an Epson-type
  dot-matrix graphics printer.  You might be more spe- cifically
  interested in the mathematical operations package: histo- gram and
  Fourier analysis, equalization, user-specified operations (e.g.
  "multiply channel 1 by 3, add channel 2, and store as channel 5"), and
  God only knows what all else -- there's a LOT.  I don't have and don't
  use these, so can't say much about them; you only buy the packages your
  particular application/interest calls for.

  Each utility is controlled by from one to eight "parameters," read from
  a common "parameter file" which must be (in VMS anyway) in your "default
  directory."  Some utilities will share parameters and use the same
  parameter for a different purpose, so it can get a bit confusing setting
  up a series of operations.  The standard PCI environment contains a
  scripting language very similar to IBM-PC BASIC, but which allows you to
  automate the process of setting up parameters for a common, complicated,
  lengthy or difficult series of utility executions.  (In VMS I can also
  invoke utilities independently from a DCL command procedure.)  There's
  also an optional programming library which allows you to write compiled
  language programs which can interface with (read from/write to) the PCI
  data structures (database file, parameter file).

  The PCI software is designed specifically for remote-sensing images, but
  requires such a level of operator expertise that, once you reach the
  level where you can handle r-s images, you can figure out ways to handle
  a few other things as well.  For instance, the Tape I/O package offers a
  utility for reading headerless multi-band (what Adobe PhotoShop on the
  Macintosh calls "raw") data from tape, in a number of different
  "interleave" orders. This turns out to be ideal for manipulating the
  graphic-arts industry's "CT2T" format, would probably (I haven't tried)
  handle Targa, and so on. Above all, however, you HAVE TO KNOW WHAT
  YOU'RE DOING or you can screw up to the Nth degree and have to start
  over.  It's worth noting that the PCI "database" file is designed to
  contain not only "raster" (image) data, but vectors (for overlaying map
  information entered via digitizing table), land-use, and all manner of
  other information (I observe that a remote-sensing image tape often
  contains all manner of information about the spectral bands, latitude,
  longitude, time, date, etc. of the original satellite pass; all of this
  can go into the PCI "database").

  I _believe_ that on workstations the built-in display is used.  On VAX
  systems OTHER than workstations PCI supports only a couple of specific
  third-party display systems (the name Gould/Deanza seems to come to
  mind).  One of MY personal workarounds was a display program which would
  display directly from a PCI "database" file to a Peritek VCT-Q (Q-bus
  24-bit DirectColor) display subsystem.  PCI software COULD be "overkill"
  in your case; it seems designed for the very "high end"
  applications/users, i.e. those for whom a Mac/PC largely doesn't suffice
  (although as you know the gap is getting smaller all the time).  It's
  probably no coincidence that PCI is located in Canada, a country which
  does a LOT of its land/resource management via remote sensing; I believe
  the Canadian government uses PCI software for some of its work in these
  areas.

SPAM (Spectral Analysis Manager)
--------------------------------
  Back in 1985 JPL developed something called SPAM (Spectral Analysis
  Manager) which got a fair amount of use at the time.  That was designed
  for Airborne Imaging Spectrometer imagery (byte data, <= 256 pixels
  across by <= 512 lines by <= 256 bands); a modified version has since
  been developed for AVIRIS (Airborne VIsual and InfraRed Imaging
  Spectrometer) which uses much larger images.

  Spam does none of these things (rectification, classification, PC and
  IHS transformations, filtering, contrast enhancement, overlays).
  Actually, it does limited filtering and contrast enhancement
  (stretching).  Spam is aimed at spectral identification and clustering.

  The original Spam uses X or SunView to display.  The AVIRIS version may
  require VICAR, an executive based on TAE, and may also require a frame
  buffer.  I can refer you to people if you're interested.  PCW requires X
  for display.

MAP II

  Among the Mac GIS systems, MAP II is distributed by John Wiley.
