SYNOPSIS

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

DESCRIPTION

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

OPTIONS

20       -visual visual
21               Specify which visual to use.  Legal values are the  name  of  a
22               visual  class,  or the id number (decimal or hex) of a specific
23               visual.
24
25       -window Draw on a newly-created window.  This is the default.
26
27       -root   Draw on the root window.
28
29       -count number
30               How many balls to display.  Default: 300.
31
32       -size number
33               Maximum size of each ball.  Default: 25.
34
35       -gravity number
36               Coefficient of gravity.  Useful values  are  <  0.1.   Default:
37               0.01.
38
39       -wind number
40               Wind.  Useful values are < 0.1.  Default: 0.00.
41
42       -elasticity number
43               Coefficient  of  elasticity.   Useful  values  are  0.2 to 1.0.
44               Default: 0.97.  Lower numbers make less bouncy balls.
45
46       -delay number
47               Per-frame delay, in microseconds.  Default:  10000  (0.01  sec‐
48               onds.).
49
50       -nonrandom
51               Make all balls be the same size.
52
53       -no-nonrandom
54               Make the balls be random sizes.  Default.
55
56       -shake | -no-shake
57               Whether  to  shake  the box if the system seems to have settled
58               down.  "Shake" means "change the direction of Down."
59
60       -fps    Display the current frame rate and CPU load.
61

ENVIRONMENT

63       DISPLAY to get the default host and display number.
64
65       XENVIRONMENT
66               to get the name of a resource file that  overrides  the  global
67               resources stored in the RESOURCE_MANAGER property.
