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 dropping characters similar to what is  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.
