Geomview for Nextstep
Here's information about Geomview. We distribute fat NeXTStep binaries which will work on both NeXT hardware and 486's. If you have a more specific question we can give you a more specific answer. Tamara Munzner ((555) 555-5555 munzner at geom.umn.edu The Geometry Center ======================================================================== Geomview/OOGL Release 1.4.2 The Geometry Center April 28, 1993 -------------- INTRODUCTION ------------ This is version 1.4.2 of Geomview/OOGL. It runs on Silicon Graphics IRIS workstations, on NeXT computers under NeXTStep 3.0, and on NextStep/Intel under NeXTStep 3.1. A beta release of a generic X version is also available. 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 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. INSTALLATION ------------ See the INSTALL file for installation details. Disk space required: geomview-next.tar, installed 15.5 MB geomview-sgi.tar.Z, untarred 15.1 MB geomview.tar.Z source only, untarred 7 MB source, compiled for Next (fat binaries) & SGI 107 MB source, compiled for SGI only 80 MB Editing makefiles/Makedefs.global to set COPTS = -O rather than the default COPTS = -g yields: source, compiled for SGI only, COPTS=-O 61 MB source, compiled for NeXT, fat binaries, COPTS=-O 52 MB 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: MODULE PLATFORMS DESCRIPTION 4dview: S 4-dimensional slicing & rotation CellularAutomata: S cellular automata animation animate: SNX flip through a sequence of objects clipboard: S cut, copy and paste geometric objects corners: S create vector skeleton of object crayola: SN interactively color objects drawbdy: SNX compute and draw the boundary of an object flythrough: S interactive version of "Not Knot" hyperbolic flythrough ginsu: S interactively slice objects graffiti: SN draw line segments on objects gvclock: SNX 3D clock, demonstrates real-time motion hinge: S hinge copies of a polyhedron around its edges maniview: S 3-manifold viewer NDview: S N-dimensional viewing controls and demonstration NDdemo: S N-dimensional viewing demonstration nose: SN demonstrates picking pssnap: SNX generate PostScript snapshot stereo: S hardware, crosseyed, red/cyan stereo (beta version) sweep: SN generate objects of rotation from line segments tackdown: S redefine an object's "home" position transformer: S explicitly control an object's transformation matrix trigrp: S explore triangle symmetry groups warp: SN interactively deform an object AUXILIARY PROGRAMS ------------------- PROGRAM PLATFORMS DESCRIPTION anytooff: SNX convert any OOGL object into OFF format bdy: SNX compute the boundary edges of a geom as a VECT file geomstuff: SX pipe your program's OOGL data to geomview via a pipe math2oogl: SNX convert Mathematica graphics object to OOGL format offconsol: SNX consolidate duplicate vertices in an OFF file oogl2rib SNX convert OOGL to RenderMan RIB (see OOGL.m.doc) togeomview: SNX pipe GCL commands or geometry to a copy of geomview, invoking geomview if necessary (S means SGI version exists, N means NeXTStep version exists, X means X version exists) DOCUMENTATION ------------- A comprehensive manual is in the "doc" subdirectory. 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 manual man/cat5/oogl.5 OOGL file format reference manual doc/OOGL.m.doc documentation for interface to Mathematica GEOMVIEW E-MAIL --------------- There are three 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. register at 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 REGISTRY for more details. Please do not send bug reports or questions to this address; use "firstname.lastname@example.org" for that. 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 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, and Quick RenderMan on the NeXT. 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. MISCELLANEOUS ------------- For a list of changes between versions, 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 ---------- Picking does not work if any part of any object is behind the camera plane. IMPROVEMENTS/WISH LIST ---------------------- More modules will be converted to NeXTStep, and the way modules are handled on under NeXTSTEP should improve.
