glmatrix(6)

NAME
glmatrix - simulates the title sequence effect of the movie

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

DESCRIPTION
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(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.

-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.

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.
