NAME
       gltext - draws text spinning around in 3D

SYNOPSIS
       gltext [-display host:display.screen] [-window] [-root] [-visual
       visual] [-delay microseconds] [-text string] [-program command]
       [-wander] [-no-wander] [-spin axes] [-no-spin] [-front] [-no-front]
       [-wireframe] [-fps]

DESCRIPTION
       The gltext program draws some text spinning around in 3D, using a font
       that appears to be made of solid tubes.

OPTIONS
       gltext accepts the following options:

       -window Draw on a newly-created window.  This is the default.

       -root   Draw on the root window.

       -install
               Install a private colormap for the window.

       -visual visual
               Specify which visual to use.  Legal values are the name of a
               visual class, or the id number (decimal or hex) of a specific
               visual.

       -text string
               The text to display.  This may contain newlines, but it
               shouldn't be very long.  The default is to display the machine
               name and OS version.

               This may also be a format string acceptable to date(1) and
               strftime(3), in which case, it will be updated once a second.
               So to make this program display a spinning digital clock, you
               could do this:
               gltext -text "%A%n%d %b %Y%n%l:%M:%S %p"
               To include a literal `%', you must double it: `%%'.

               See the man page for strftime(3) for more details.

       -program command
               The given program is run, and its output is displayed.  If
               specified, this overrides -text.  The program will be re-run
               every 5 seconds to re-generate the text.  It should run
               quickly, and shouldn't generate too much text.

       -wander Move the text around the screen.  This is the default.

       -no-wander
               Keep the text centered on the screen.

       -spin   Which axes around which the text should spin.  The default is
               "XYZ", meaning rotate it freely in space.  "-spin Z" would
               rotate the text in the plane of the screen while not rotating
               it into or out of the screen; etc.

       -no-spin
               Don't spin the text at all: the same as -spin "".

       -front  When spinning, never spin all the way around or upside down:
               always face mostly forward so that the text is easily readable.

       -no-front
               Allow spins to go all the way around or upside down.  This is
               the default.

       -wireframe
               Render in wireframe instead of solid.

       -fps    Display the current frame rate, CPU load, and polygon count.

ENVIRONMENT
       DISPLAY to get the default host and display number.

       XENVIRONMENT
               to get the name of a resource file that overrides the global
               resources stored in the RESOURCE_MANAGER property.
