interaggregate man page

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

Synopsis

interaggregate [-display host:display.screen] [-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.

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.

Bugs

Setting the background to anything besides black confuses the intensity
algorithm and will look terrible.
