- INTRODUCTION
- ------------
-
- This is version 1.6.1 of Geomview/OOGL. It runs on many UNIX workstations
- using X/Motif, including Silicon Graphics, Sun, Linux, HP-UX, DEC Alpha,
- and RS/6000, using plain Xlib graphics, Open GL if available, or GL (on SGIs).
- A version also runs on NextStep 3.1 or later using Quick Renderman graphics.
-
- Geomview is an interactive geometry viewing program. OOGL, which
- stands for Object Oriented Graphics Library, is the library upon
- which Geomview is built.
-
- NOTE: Please read the file REGISTER. We need to know how our
- users are using Geomview so that we can better serve you.
-
- In addition, if you use geomview please send an email note to
- geomview-users-request@geom.umn.edu requesting to be added to the
- geomview-users mailing list; this list is for announcements
- regarding geomview and for geomview users to communicate with
- each other. See the details in the GEOMVIEW E-MAIL section
- below.

- MORE ABOUT GEOMVIEW
- -------------------
-
- Geomview represents the current state of an ongoing effort at the
- Geometry Center to provide interactive geometry software which is
- particularly appropriate for mathematics research and education.
- In particular, geomview can display things in hyperbolic and
- spherical space as well as Euclidean space.
-
- Geomview allows multiple independently controllable objects and
- cameras. It provides interactive control for motion, appearances
- (including lighting, shading, and materials), picking on an
- object, edge or vertex level, snapshots in SGI image file or
- Renderman RIB format, and adding or deleting objects is provided
- through direct mouse manipulation, control panels, and keyboard
- shortcuts. External programs can drive desired aspects of the
- viewer (such as continually loading changing geometry or
- controlling the motion of certain objects) while allowing
- interactive control of everything else.
-
- Geomview supports the following simple data types: polyhedra with
- shared vertices (.off), quadrilaterals, rectangular meshes,
- vectors, and Bezier surface patches of arbitrary degree including
- rational patches. Object hierarchies can be constructed with
- lists of objects and instances of object(s) transformed by one or
- many 4x4 matrices. Arbitrary portions of changing hierarchies
- may be transmitted by creating named references.
-
- Geomview can display Mathematica and Maple 3-D graphics output; for
- information on this see the files OOGL.m.doc and gvplot.doc, respectively,
- in the "doc" subdirectory.
-
-
- EXTERNAL MODULES
- ----------------
-
- Geomview comes with several "external modules" --- programs that
- communicate with geomview through a command language. The list
- of currently installed modules appears in the "Modules" browser
- on geomview's main panel. To invoke a module, click the mouse on
- the appropriate line in this browser. The modules in this
- distribution are:

- DOCUMENTATION
- -------------
-
- A comprehensive manual is in the "doc" subdirectory. This manual
- was written specifically for the SGI version. Most, but not all
- of it, applies to the NeXT and X11 version as well. There is
- also a copy of this manual on the World Wide Web at URL:
- http://www.geom.umn.edu/docs/software/geomview/geomview_toc.html.
-
- The file doc/oogltour gives an introduction to the OOGL file
- format, which is the format of geometry files that geomview
- reads. More details are in the manual.
-
- Further documentation is in the "man" directory, which contains
- Unix manual pages in both nroff source and formatted form. Each
- external module, as well as geomview itself, has a manual
- page. Of particular interest are:
-
- man/cat1/geomview.1 geomview man page
- man/cat5/geomview.5 geomview command language reference
- man/cat5/oogl.5 OOGL file format reference
- doc/OOGL.m.doc documentation for interface to Mathematica
- doc/gvplot.doc documentation for interface to Maple
-
-
- GEOMVIEW E-MAIL
- ---------------
-
- There are three electronic mail addresses for communication
- regarding geomview:
-
- geomview-users@geom.umn.edu:
-
- This is a mailing list of people using geomview and can be used
- for communication between users regarding geomview problems,
- questions, experiences, etc. The geomview authors are also a part
- of this list and will respond to questions posted to it. We also
- use this list to make announcements about new releases and other
- things of interest to users. To be added to or removed from the
- geomview-users list, send a note to geomview-users-request@geom.umn.edu
-
- software@geom.umn.edu:
-
- This is the "official" support line; it reaches the geomview
- authors directly. In general if you have a question or comment
- that may be of interest to other users, send it to the
- "geomview-users" address. Use "software" for communication
- intended just for the authors; in particular, send bug reports and
- suggestions for improvement to this address.
-
- register@geom.umn.edu
-
- Use this address to tell us what you are doing with Geomview. The
- Geometry Center is funded by the National Science Foundation, and
- it is important that we be able to report to NSF the ways in which
- our software is being used. If you use Geomview in your work
- please send us a note at this address telling us what you are
- doing with it. See the file REGISTER for more details. Please do
- not send bug reports or questions to this address; use
- "software@geom.umn.edu" for that.

-
- HISTORY
- -------
-
- This project began in the summer of 1988 with the work of Pat
- Hanrahan on a viewing program called MinneView. Shortly
- thereafter Charlie Gunn begin developing OOGL in conjunction with
- MinneView. In the time since then, many people have contributed,
- including Stuart Levy, Mark Meuer, Tamara Munzner, Steve
- Anderson, Mario Lopez, Todd Kaplan.
-
- In 1991, OOGL was rewritten and a new viewer geomview was begun.
- Both geomview and the new OOGL have a core of device-independent
- common code. Currently there are device drivers for SGI GL,
- PhotoRealistic RenderMan, Quick RenderMan on the NeXT, and the X
- Window System. The NeXT version of geomview was written by
- Daniel Krech and Scott Wisdom. Scott Wisdom wrote the Photo
- Realistic and Quick RenderMan OOGL drivers. The SGI version of
- geomview and OOGL was written by Stuart Levy, Tamara Munzner, and
- Mark Phillips. The geomview common kernel was written by Stuart
- Levy, Tamara Munzner, and Mark Phillips, with contributions from
- Nathaniel Thurston and Celeste Fowler. The X version was created
- by Daeron Meyer and Timothy Rowley.
