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