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.
