NAME

        fluidballs - the physics of bouncing balls.
 

SYNOPSIS

        fluidballs  [-display  host:display.screen]  [-visual visual] [-window]
        [-root] [-count number] [-size number] [-gravity number] [-wind number]
        [-elasticity number] [-delay number] [-nonrandom] [-no-shake] [-fps]
 

DESCRIPTION

        Models  the  physics  of  bouncing  balls,  or of particles in a gas or
        fluid, depending on the settings. If  "Shake  Box"  is  selected,  then
        every  now  and then, the box will be rotated, changing which direction
        is down (in order to keep the settled balls in motion.)
 

OPTIONS

        -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.
 
        -count number
                How many balls to display.  Default: 300.
 
        -size number
                Maximum size of each ball.  Default: 25.
 
        -gravity number
                Coefficient of gravity.  Useful values  are  <  0.1.   Default:
                0.01.
 
        -wind number
                Wind.  Useful values are < 0.1.  Default: 0.00.
 
        -elasticity number
                Coefficient  of  elasticity.   Useful  values  are  0.2 to 1.0.
                Default: 0.97.  Lower numbers make less bouncy balls.
 
        -delay number
                Per-frame delay, in microseconds.  Default:  10000  (0.01  sec-
                onds.).
 
        -nonrandom
                Make all balls be the same size.
 
        -no-nonrandom
                Make the balls be random sizes.  Default.
 
        -shake | -no-shake
                Whether  to  shake  the box if the system seems to have settled
                down.  "Shake" means "change the direction of Down."
 
        -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.
