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
               output of this program will be repeatedely displayed, with new pages of text  shifting  in  every
               few seconds.  Lines should be relatively short.  You might try:
               -program 'xscreensaver-text --cols 20'

       -maxlines
               Set  the  number of lines of text to display.  By default, gltext will print 8 lines of text at a
               time.  Use this option to increase or decrease that number.  Be aware that gltext is designed  to
               work  with  a  fairly  small  amount of text, so setting this value too high might result in slow
               performance or strange behaviour stemming from buffer overflows.  Increase at your own risk.

       -mono   Display the text in a monospace font.  Default is a variable-width font.

       -no-mono
               Display the text in a variable-width font.  This is the default.

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

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

       -wander-speed
               Sets the speed at which the text wanders around.  Default is 0.02.

       -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.

       -scale  Sets  the scale at which the text is rendered.  Bigger values will result in bigger text; smaller
               values will result in smaller text.  The default value is 0.01.

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.
