SYNOPSIS

9       goop  [-display  host:display.screen]  [-foreground color] [-background
10       color] [-window] [-root] [-mono] [-install] [-visual  visual]  [-trans‐
11       parent] [-non-transparent] [-additive] [-subtractive] [-xor] [-no-xor]

DESCRIPTION

14       The goop program draws a simulation of bubbles in layers of overlapping
15       multicolored translucent fluid.
16

OPTIONS

18       goop accepts the following options:
19
20       -window Draw on a newly-created window.  This is the default.
21
22       -root   Draw on the root window.
23
24       -mono   If on a color display, pretend we're on a monochrome display.
25
26       -install
27               Install a private colormap for the window.
28
29       -visual visual
30               Specify which visual to use.  Legal values are the  name  of  a
31               visual  class,  or the id number (decimal or hex) of a specific
32               visual.
33
34       -count integer
35               How many bubbles to draw per layer.  Default: random.
36
37       -planes integer
38               How many planes to draw.   Default:  random,  based  on  screen
39               depth.
40
41       -delay microseconds
42               How  much  of a delay should be introduced between steps of the
43               animation.  Default 12000, or about 0.012 seconds.
44
45       -transparent
46               If -layers is greater than 1, then each layer will be drawn  in
47               one  color,  and  when  they overlap, the colors will be mixed.
48               This is the default.
49
50       -non-transparent
51               Turns off -transparent.
52
53       -additive
54               If -transparent is specified, then this option means  that  the
55               colors  will  be mixed using an additive color model, as if the
56               blobs were projected light.  This is the default.
57
58       -subtractive
59               If -transparent is specified, then this option means  that  the
60               colors will be mixed using a subtractive color model, as if the
61               blobs were translucent filters.
62
63       -xor    Draw with xor instead of the other color tricks.
64

ENVIRONMENT

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