NAME

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

SYNOPSIS

intermomentary [--display host:display.screen] [--visual visual]
[--window] [--root] [--window-id number] [--foreground color]
[--background color] [--num-discs disc count] [--draw-delay delayms]
[--max-riders maxr] [--max-radius maxradius] [--fps]

DESCRIPTION

The Intersection Momentary 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.

The circles begin with a radius of 1 pixel and slowly increase to
some arbitrary size. Circles are drawn with small moving points
along the perimeter. The intersections are rendered as glowing orbs.
Glowing orbs are rendered only when a perimeter point moves past the
intersection point.

OPTIONS

Intermomentary accepts the following options:

--num-discs disc count (Default: 85)
Number of slowly moving and growing discs to use. The more
discs, the more CPU power.

--draw-delay delayms (Default: 30000)
Delay in ms between drawing cycles. More delay, slower (but
smoother and less CPU intensive.) art.

--max-riders maxrider (Default: 40)
Maximum number of 'riders', single dots moving around the
edge of the discs.

--max-radius maxradius (Default: 100)
Maximum possible radius of a disc.

--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.

BUGS

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

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.
