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 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.
