GL Viewer is a [GRASP][1] movie viewer for the Macintosh, based on
xgrasp an X Window system GL viewer, itself derived from GRASP by
Microtex Industries, Inc. an animated graphics system developed for
the PC AT/XT systems of the 1980's using the [GRASP GL library
format][2] \- For an example, see "[juggler.gl][3]" from 1989 (last
item in page).

> This Compactor Pro archive contains GL Viewer 1.1.1, a THINK C port
> of glib (from the xgrasp 1.7 distribution), THINK C sources, GL
> documentation, and a sample GL library. This distribution completely
> replaces the 1.1 distribution. Please note that GL Viewer was built
> presupposing a 68020, a 68881, and 32-bit QuickDraw, and that it
> works best with an 8-bit color monitor.
>
> Most of this work is derived from software copyright (c) 1991 by
> Patrick J. Naughton.

> Although I have only added -- and not removed -- functionality to
> these programs, I am interested in obtaining any file that causes GL
> Viewer to crash your system. (N.b.: this release fixes all the known
> pathological problems in 1.0. ...So get your returns in early!)
>
> A note for X11 hackers: Because much of the functionality that I've
> added could be integrated into the "normal" xgrasp distribution, ...
> "fly and be free!" ![Smile][4]
