ifs — draws spinning, colliding iterated-function-system images

Synopsis

ifs [-display host:display.screen] [-visual visual] [-window] [-root] [-no-db] [-delay number] [-detail number] [-colors number] [-functions number] [-iterate | -recurse] [-no-rotate] [-no-scale] [-no-translate] [-fps]

Description

The ifs program draws spinning, colliding iterated-function-system images.

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.
-no-db
Disable double-buffering.
-delay number
Per-frame delay, in microseconds. Default: 20000
-colors number
Number of colours to use. Default: 200
-detail number
In -iterate mode, number of times to randomly iterate the functions, in thousands. In -recurse mode, number of times to apply functions (recursion depth) before drawing each point. Default: 9
-functions number
Number of functions to be iterated. Default: 3
-iterate
Calculate by iteratively applying the functions in a random order, usually faster than -recurse. This is the default.
-recurse
Calculate by recursively applying all combinations of the functions. This is the historical behavior and may produce neater output than -iterate.
-no-rotate
Disable the rotation component of the functions.
-no-scale
Disable the scaling component of the functions.
-no-translate
Disable the varying translation component of the functions.
-no-multi
Turn off multi-coloured mode, only one colour is used to colour the whole set.
-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.
