glmatrix(6x) XScreenSaver manual glmatrix(6x) NAME glmatrix - simulates the title sequence effect of the movie SYNOPSIS glmatrix [-display host:display.screen] [-window] [-root] [-install] [-visual visual] [-delay usecs] [-speed ratio] [-density pct] [-no-fog] [-no-waves] [-no-rotate] [-binary] [-hexadecimal] [-dna] [-clock] [-timefmt fmt] [-wireframe] [-fps] 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(6x) for a 2D rendering of the similar effect that ap- peared 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: de- fault 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 ze- ros. -hexadecimal Instead of displaying Matrix glyphs, display hexadecimal dig- its. -dna Instead of displaying Matrix glyphs, display genetic code (gua- nine, 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.
