glmatrix − simulates the title sequence effect of the movie
glmatrix [−−display host:display.screen] [−−window] [−−root] [−−window−id number][−−install] [−−visual visual] [−−delay usecs] [−−speed ratio] [−−density pct] [−−no−fog] [−−no−waves] [−−no−rotate] [−−binary] [−−hexadecimal] [−−dna] [−−clock] [−−timefmt fmt] [−−wireframe] [−−fps]
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.
glmatrix
accepts the following options:
−−window
Draw on a newly-created window. This is the default.
|
−−root |
Draw on the root window. |
−−window−id number
Draw on the specified 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. |
|
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.
XSCREENSAVER_WINDOW
The window ID to use with −−root.
