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

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.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.

       gltext - draws text spinning around in 3D

gltext accepts the following options:

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

       --root  Draw on the root window.

       --window-idnumber
               Draw on the specified window.

       --install
               Install a private colormap for the window.

       --visualvisual
               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.

       --textstring
               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.

       --programcommand
               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.  "--spinZ" 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.
