glmatrix — simulates the title sequence effect of the movie

Synopsis

glmatrix [-display host:display.screen] [-window] [-root] [-install] [-visual visual] [-delay usecs] [-speed ratio] [-density pct] [-no-fog] [-no-waves] [-no-rotate] [-binary] [-hexadecimal] [-dna] [-clock] [-timefmt fmt] [-wireframe] [-fps]

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(6x) 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.
-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.
