NAME¶

interaggregate - Visualize the momentary and aggregate intersections between slowly moving circles.

SYNOPSIS¶

interaggregate [--display host:display.screen] [--visual visual] [--window] [--root] [--window-id number] [--foreground color] [--background color] [--num-circles disc count] [--growth-delay delayms] [--max-cycles maxr] [--percent-orbits percent] [--base-orbits percent] [--base-on-center] [--draw-centers] [--fps]

DESCRIPTION¶

The Intersection Aggregate is a fun visualization defining the relationships between objects with Casey Reas, William Ngan, and Robert Hodgin. Commissioned for display at the Whitney Museum of American Art.

A surface filled with 100 medium to small sized circles. Each circle has a different size and direction, but moves at the same slow rate. Display:

A. The instantaneous intersections of the circles.
B. The aggregate intersections of the circles.

OPTIONS¶

interaggregate accepts the following options:

--num-circles disc count (Default: 100)

Number of slowly moving and growing discs to use. The more discs, the more CPU power.

--growth-delay delayms (Default: 18000)

Delay in ms between drawing cycles. More delay, slower (but smoother and less CPU intensive.) art.

--fps

Display the current frame rate and CPU load.

--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.

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.

BUGS¶

Setting the background to anything besides black confuses the intensity

algorithm and will look terrible.
