NAME
       interference - decaying sinusoidal waves


SYNOPSIS
       interference [-display host:display.screen] [-visual visual] [-window] [-root] [-count number] [-gridsize
       number] [-delay number] [-speed number] [-radius number] [-ncolors number]  [-color-shift  number]  [-hue
       number] [-no-db] [-fps]


DESCRIPTION
       Another  color-field  hack,  this  one works by computing decaying sinusoidal waves, and allowing them to
       interfere with each other as their origins move.


OPTIONS
       -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.

       -window Draw on a newly-created window.  This is the default.

       -root   Draw on the root window.

       -count number
               Number of Waves.  0 - 20.  Default: 3.

       -gridsize number
               Magnification. 1 - 20.  Default: 4.

       -delay number
               Per-frame delay, in microseconds.  Default: 30000 (0.03 seconds.).

       -speed number
               Wave Speed.  1 - 100.  Default: 30.

       -radius number
               Wave Size.  50 - 1500.   Default: 800.

       -ncolors number
               Number of Colors.  Default: 128.

       -color-shift number
               Color Contrast.  0 - 100.  Default: 60.

       -hue number
               Hue of the base color (0-360, as in HSV space.)  Default 0, meaning random.

       -db | -no-db
               Whether to double buffer.

       -fps    Display the current frame rate and CPU load.


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.
