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.
