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: 2.
-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: 192.
-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.
