SYNOPSIS

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]

DESCRIPTION

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(6) for a 2D rendering of the similar effect that
appeared on the computer monitors actually in the movie.

OPTIONS

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.

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.

XSCREENSAVER_WINDOW
The window ID to use with --root.
