glmatrix - simulates the title sequence effect of the movie

glmatrix [-display host:display.screen] [-window] [-root] [-install] [-visual visual] [-delay usecs] [-density percentage] [-top | -bottom | -both] [-small | -large] [-trace] [-phone number] [-wireframe] [-fps]

The glmatrix program draws dropping characters similar to what is seen in the title sequence of the Wachowski brothers' film, "The Matrix".

Also see xmatrix(1) 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.

-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.

-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.)

-wireframe

Just draw boxes instead of textured characters.

-fps

Display a running tally of how many frames per second are being rendered. In conjunction with -delay 0, this can be a useful benchmark of your GL performance.

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.
