15 The glmatrix program draws the 3D "digital rain" effect, as seen in the
16 title sequence of the Wachowski brothers' film, "The Matrix".
17 Also see xmatrix(6x) for a 2D rendering of the similar effect that ap‐
19 peared on the computer monitors actually in the movie.

22 glmatrix accepts the following options:
23 --window
25 Draw on a newly-created window. This is the default.
26 --root Draw on the root window.
28 --window-id number
30 Draw on the specified window.
31 --install
33 Install a private colormap for the window.
34 --visual visual
36 Specify which visual to use. Legal values are the name of a
37 visual class, or the id number (decimal or hex) of a specific
38 visual.
39 --delay usecs
41 The delay between frames of the animation, in microseconds: de‐
42 fault 30000.
43 --speed ratio
45 How fast the glyphs should move; default 1.0. 2.0 means twice
46 as fast, 0.5 means half as fast.
47 --density percentage
49 The approximate percentage of the screen that should be filled
50 with characters at any given time. Default 20%.
51 --no-fog
53 By default, glyphs are dimmer the farther away they are. This
54 argument disables that.
55 --no-waves
57 By default, waves of color roll down the columns of glyphs.
58 This argument disables that.
59 --no-rotate
61 By default, the scene slowly tilts and rotates. This argument
62 disables that.
63 --binary
65 Instead of displaying Matrix glyphs, only display ones and ze‐
66 ros.
67 --hexadecimal
69 Instead of displaying Matrix glyphs, display hexadecimal dig‐
70 its.
71 --dna Instead of displaying Matrix glyphs, display genetic code (gua‐
73 nine, adenine, thymine, and cytosine.)
74 --clock Hide a clock displaying the current time somewhere in the
76 glyphs.
77 --timefmt strftime-string
79 How to format the clock when --clock is specified. Default
80 " %l%M%p ".
81 --speed ratio
83 Less than 1 for slower, greater than 1 for faster. Default 1.
84 --wireframe
86 Just draw boxes instead of textured characters.
87 --fps Display the current frame rate, CPU load, and polygon count.
89
91 DISPLAY to get the default host and display number.
92 XENVIRONMENT

95 resources stored in the RESOURCE_MANAGER property.
