gltext (6x)

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]

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

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 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.

-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 "".

-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.

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.
