Usage

Overview

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.
