glmatrix(6) XScreenSaver manual glmatrix(6) NAME glmatrix - simulates the title sequence effect of the movie SYNOPSIS 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] [--hexa- decimal] [--dna] [--clock] [--timefmt fmt] [--wireframe] [--fps] DESCRIPTION The glmatrix program draws the 3D "digital rain" effect, as seen in the ti- tle 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. --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 ar- gument 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 dis- ables 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 re- sources stored in the RESOURCE_MANAGER property. XSCREENSAVER_WINDOW The window ID to use with --root. SEE ALSO xmatrix(6), X(1), xscreensaver(1) COPYRIGHT Copyright (C) 1999-2003 by Jamie Zawinski.
