Below is the README from the latest release. Tamara Munzner ((555) 555-5555 munzner at geom.umn.edu The Geometry Center Geomview/OOGL Release 1.3.2 The Geometry Center March 1, 1993 ---------------- INTRODUCTION ------------ This is version 1.3.2 of Geomview/OOGL. It runs on Silicon Graphics IRIS workstations. This directory contains the binary distribution; for information on the source code, see the SOURCE CODE section below. Geomview is an interactive geometry viewing program. OOGL, which stands for Object Oriented Graphics Library, is the library upon which Geomview is built. If you use geomview please send an email note to geomview-users-request at 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. RUNNING GEOMVIEW ---------------- To run geomview, cd to this directory and type "geomview". The current directory must be this directory (the one containing this README file and the "geomview" file) in order for this to work. If you want to be able to run geomview from a directory other than this directory, or if you want to install it permanently on your system, edit the file "geomview" with any text editor. It is a shell script that starts up geomview after setting some appropriate environment variables, and has comments at the top telling you what to do. 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 graphics output; for information on this see the file OOGL.m.doc 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 "Applications" 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: 4dview: 4-dimensional slicing & rotation animate: flip through a sequence of objects corners: create vector skeleton of object crayola: interactively color objects eucsyms: explore the 230 3D Euclidean symmetry groups flythrough: interactive version of "Not Knot" hyperbolic flythrough ginsu: interactively slice objects graffiti: draw line segments on objects gvclock: 3D clock, demonstrates real-time motion hinge: hinge copies of a polyhedron around its edges linkmover: evolve a link in 3-space maniview: 3-manifold viewer nose: demonstrates picking pssnap: generate PostScript snapshot stereo: supports hardware, crosseyed, red/cyan stereo (beta version) sweep: generate objects of rotation from line segments tackdown: redefine an object's "home" position transformer: explicitly control an object's transformation matrix trigrp: explore triangle symmetry groups warp: interactively deform an object AUXILLIARY PROGRAMS ------------------- anytooff: convert any OOGL object into OFF format bdy: compute the boundary edges of a geom as a VECT file geomstuff: utility to send your program's output to geomview via a pipe math2oogl: convert Mathematica graphics object to OOGL (see OOGL.m.doc) offconsol: consolidate duplicate vertices in an OFF file oogl2rib: convert OOGL to RenderMan RIB (see OOGL.m.doc) DOCUMENTATION ------------- The file doc/overview gives a general overview of geomview. The file doc/oogltour goes into more detail about the OOGL file format, which is the format of geometry files that geomview reads. 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 manual man/cat5/oogl.5 OOGL file format reference manual doc/OOGL.m.doc documentation for interface to Mathematica DISK SPACE REQUIREMENTS ----------------------- The geomview distribution file, geomview.tar.Z, occupies about 4 megabytes. Unpacked, the distribution occupies about 7.5 megabytes. This includes geomview, its documentation, example files, and many geomview modules. If you do not have enough space for all of this you may obtain various pieces of the distribution separately via anonymous ftp from geom.umn.edu. SOURCE CODE ----------- The source code for geomview/OOGL is available via anonymous ftp from geom.umn.edu. With this release we have decided to concentrate more on packaging the binary version and less on the source code. It is our experience that the majority of our users are more interested in running geomview than in looking at or modifying its source code. At the time of this writing the source code for the present version is not yet ready for distribution, but older versions are available. If you are interested in obtaining the source code for the present version send a note to firstname.lastname@example.org and we will try to speed the process of packaging it up. HISTORY ------- This project began in the sumer 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 Mark Meuer, Steve Anderson, Mario Lopez, Todd Kaplan. The current version was written by Stuart Levy, Tamara Munzner, Mark Phillips, and Celeste Fowler. Charlie Gunn has continued to work on OOGL, Scott Wisdom wrote the Renderman driver, and Nathaniel Thurston wrote the motion code. GEOMVIEW E-MAIL --------------- There are two electronic mail addresses for communication regarding geomview: geomview-users at 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 at geom.umn.edu email@example.com: 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. MISCELLANEOUS ------------- For a list of changes since the last version (1.2.3), see the file CHANGES. Geomview is copyrighted software. Please read the file COPYING in this directory before using or distributing Geomview. The file MANIFEST contains a list of the files in this distribution. KNOWN BUGS ---------- The conformal-ball model of hyperbolic space is not yet fully implemented. It only works with polylist (OFF) objects and does not work at all in "flat" shading mode. Picking does not work if any part of any object is behind the camera plane.
