NAME
glmatrix - simulates the title sequence effect of the
movie
SYNOPSIS
glmatrix [-display host:display.screen] [-window] [-root] [-install] [-visual visual] [-delay usecs] [-density per_ centage] [-top | -bottom | -both] [-small | -large] [-trace] [-phone number]
DESCRIPTION
The glmatrix program draws dropping characters similar to
what is seen in the title sequence of the Wachowski broth
ers' 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.
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 hex
adecimal digits. - -dna Instead of displaying Matrix glyphs, display
- genetic code (guanine, adenine, thymine, and cyto
sine.) - -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_MAN
AGER property.
