NAME

       gltext - draws text spinning around in 3D


SYNOPSIS

       gltext   [-display   host:display.screen]  [-window]  [-root]  [-visual
       visual] [-delay microseconds] [-fps] [-text string] [-wander] [-no-wan-
       der] [-spin axes] [-no-spin]


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.

       -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 "".


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.
