The gltext program draws some text spinning around in 3D, using a font
that appears to be made of solid tubes.
gltext accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
Install a private colormap for the window.
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific
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.
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.
-wander Move the text around the screen. This is the default.
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.
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.
Allow spins to go all the way around or upside down. This is
Render in wireframe instead of solid.
-fps Display the current frame rate, CPU load, and polygon count.
DISPLAY to get the default host and display number.
to get the name of a resource file that overrides the global
resources stored in the RESOURCE_MANAGER property.
