interaggregate - Man Page

Visualize the momentary and aggregate intersections between slowly moving circles.


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]


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.


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.


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.


Draw on a newly-created window.  This is the default.


Draw on the root window.

--window-id number

Draw on the specified window.



to get the default host and display number.


to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.


The window ID to use with --root.


Setting the background to anything besides black confuses the intensity

algorithm and will look terrible.
