NAME

       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]

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.

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.
