interaggregate - Man Page
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.
