SYNOPSIS

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

DESCRIPTION

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

OPTIONS

21       --visual visual
22               Specify  which  visual  to use.  Legal values are the name of a
23               visual class, or the id number (decimal or hex) of  a  specific
24               visual.
25
26       --window
27               Draw on a newly-created window.  This is the default.
28
29       --root  Draw on the root window.
30
31       --window-id number
32               Draw on the specified window.
33
34       --count number
35               How many balls to display.  Default: 300.
36
37       --size number
38               Maximum size of each ball.  Default: 25.
39
40       --gravity number
41               Coefficient  of  gravity.   Useful  values are < 0.1.  Default:
42               0.01.
43
44       --wind number
45               Wind.  Useful values are < 0.1.  Default: 0.00.
46
47       --elasticity number
48               Coefficient of elasticity.  Useful values are 0.2 to 1.0.   De‐
49               fault: 0.97.  Lower numbers make less bouncy balls.
50
51       --delay number
52               Per-frame  delay,  in  microseconds.  Default: 10000 (0.01 sec‐
53               onds.).
54
55       --nonrandom
56               Make all balls be the same size.
57
58       --no-nonrandom
59               Make the balls be random sizes.  Default.
60
61       --shake | --no-shake
62               Whether to shake the box if the system seems  to  have  settled
63               down.  "Shake" means "change the direction of Down."
64
65       --fps   Display the current frame rate and CPU load.
66

ENVIRONMENT

68       DISPLAY to get the default host and display number.
69
70       XENVIRONMENT
71               to  get  the  name of a resource file that overrides the global
72               resources stored in the RESOURCE_MANAGER property.
73
74       XSCREENSAVER_WINDOW
75               The window ID to use with --root.
76
