NAME
       gltext - draws text spinning around in 3D

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

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.

       -fps    Display a running tally of how many frames per second are being
               rendered.   In  conjunction with -delay 0, this can be a useful
               benchmark of your GL performance.

       -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.

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.
