# interaggregate(6x)

Visualize the momentary and aggregate intersections between slowly moving circles.

## 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.
