NAME
interference - decaying sinusoidal waves
SYNOPSIS
interference [--display host:display.screen] [--visual visual] [--window] [--root] [--window-id number] [--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.
- --window-id number
-
Draw on the specified 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.
- XSCREENSAVER_WINDOW
-
The window ID to use with --root.
