NAME

       gltext - draws text spinning around in 3D

SYNOPSIS

       gltext  [--display host:display.screen] [--window] [--root] [--window-id number] [--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.

       --window-id number
               Draw on the specified 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.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.
