gltext — draws text spinning around in 3D
Synopsis
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]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.
- -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.
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.
