NAME

       glmatrix - simulates the title sequence effect of the movie

SYNOPSIS

       glmatrix  [-display  host:display.screen]  [-window] [-root] [-install]
       [-visual visual] [-delay usecs] [-density percentage] [-top | -bottom |
       -both] [-small | -large] [-trace] [-phone number]

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(1) 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.

       -binary Instead of displaying Matrix  glyphs,  only  display  ones  and
               zeros.

       -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.)

       -fps    Display a running tally of how many frames per second are being
               rendered.  In conjunction with -delay 0, this can be  a  useful
               benchmark of your GL performance.

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.
