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(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.
- -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.
