DESCRIPTION

15       The goop program draws a simulation of bubbles in layers of overlapping
16       multicolored translucent fluid.
17

OPTIONS

19       goop accepts the following options:
20
21       -window Draw on a newly-created window.  This is the default.
22
23       -root   Draw on the root window.
24
25       -mono   If on a color display, pretend we're on a monochrome display.
26
27       -install
28               Install a private colormap for the window.
29
30       -visual visual
31               Specify  which  visual  to use.  Legal values are the name of a
32               visual class, or the id number (decimal or hex) of  a  specific
33               visual.
34
35       -count integer
36               How many bubbles to draw per layer.  Default: random.
37
38       -planes integer
39               How  many  planes  to  draw.   Default: random, based on screen
40               depth.
41
42       -delay microseconds
43               How much of a delay should be introduced between steps  of  the
44               animation.  Default 12000, or about 0.012 seconds.
45
46       -transparent
47               If  -layers is greater than 1, then each layer will be drawn in
48               one color, and when they overlap, the  colors  will  be  mixed.
49               This is the default.
50
51       -non-transparent
52               Turns off -transparent.
53
54       -additive
55               If  -transparent  is specified, then this option means that the
56               colors will be mixed using an additive color model, as  if  the
57               blobs were projected light.  This is the default.
58
59       -subtractive
60               If  -transparent  is specified, then this option means that the
61               colors will be mixed using a subtractive color model, as if the
62               blobs were translucent filters.
63
64       -xor    Draw with xor instead of the other color tricks.
65
66       -fps    Display the current frame rate and CPU load.
67

ENVIRONMENT

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