DESCRIPTION

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
18       Also  see xmatrix(6x) for a 2D rendering of the similar effect that ap‐
19       peared on the computer monitors actually in the movie.

OPTIONS

22       glmatrix accepts the following options:
23
24       -window Draw on a newly-created window.  This is the default.
25
26       -root   Draw on the root window.
27
28       -install
29               Install a private colormap for the window.
30
31       -visual visual
32               Specify which visual to use.  Legal values are the  name  of  a
33               visual  class,  or the id number (decimal or hex) of a specific
34               visual.
35
36       -delay usecs
37               The delay between frames of the animation, in microseconds: de‐
38               fault 30000.
39
40       -speed ratio
41               How  fast the glyphs should move; default 1.0.  2.0 means twice
42               as fast, 0.5 means half as fast.
43
44       -density percentage
45               The approximate percentage of the screen that should be  filled
46               with characters at any given time.  Default 20%.
47
48       -no-fog By  default, glyphs are dimmer the farther away they are.  This
49               argument disables that.
50
51       -no-waves
52               By default, waves of color roll down  the  columns  of  glyphs.
53               This argument disables that.
54
55       -no-rotate
56               By  default, the scene slowly tilts and rotates.  This argument
57               disables that.
58
59       -binary Instead of displaying Matrix glyphs, only display ones and  ze‐
60               ros.
61
62       -hexadecimal
63               Instead  of  displaying Matrix glyphs, display hexadecimal dig‐
64               its.
65
66       -dna    Instead of displaying Matrix glyphs, display genetic code (gua‐
67               nine, adenine, thymine, and cytosine.)
68
69       -clock  Hide  a  clock  displaying  the  current  time somewhere in the
70               glyphs.
71
72       -timefmt strftime-string
73               How to format the clock  when  -clock  is  specified.   Default
74               " %l%M%p ".
75
76       -speed ratio
77               Less than 1 for slower, greater than 1 for faster.  Default 1.
78
79       -wireframe
80               Just draw boxes instead of textured characters.
81
82       -fps    Display the current frame rate, CPU load, and polygon count.
83

ENVIRONMENT

85       DISPLAY to get the default host and display number.
86
87       XENVIRONMENT
88               to  get  the  name of a resource file that overrides the global
89               resources stored in the RESOURCE_MANAGER property.
