glmatrix [--display host:display.screen] [--window]
[--root] [--window-id number][--install] [--visual visual]
[--delay usecs] [--speed ratio] [--density pct]
[--no-fog] [--no-waves] [--no-rotate] [--binary] [--hexadecimal] [--dna]
[--clock] [--timefmt fmt] [--wireframe] [--fps]
The glmatrix program draws the 3D "digital rain"
effect, as seen in the title sequence of the Wachowski brothers' film,
"The Matrix".
Also see xmatrix(6x) for a 2D rendering of the similar
effect that appeared on the computer monitors actually in the
movie.
glmatrix 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.
- --delay
usecs
- The delay between frames of the animation, in microseconds: default
30000.
- --speed
ratio
- How fast the glyphs should move; default 1.0. 2.0 means twice as fast, 0.5
means half as fast.
- --density
percentage
- The approximate percentage of the screen that should be filled with
characters at any given time. Default 20%.
- --no-fog
- By default, glyphs are dimmer the farther away they are. This argument
disables that.
- --no-waves
- By default, waves of color roll down the columns of glyphs. This argument
disables that.
- --no-rotate
- By default, the scene slowly tilts and rotates. This argument disables
that.
- --binary
- Instead of displaying Matrix glyphs, only display ones and zeros.
- --hexadecimal
- Instead of displaying Matrix glyphs, display hexadecimal digits.
- --dna
- Instead of displaying Matrix glyphs, display genetic code (guanine,
adenine, thymine, and cytosine.)
- --clock
- Hide a clock displaying the current time somewhere in the glyphs.
- --timefmt
strftime-string
- How to format the clock when --clock is specified. Default
" %l%M%p ".
- --speed
ratio
- Less than 1 for slower, greater than 1 for faster. Default 1.
- --wireframe
- Just draw boxes instead of textured characters.
- --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.
- XSCREENSAVER_WINDOW
- The window ID to use with --root.
