The goop program draws a simulation of bubbles in layers of overlapping multicolored translucent fluid.
goop accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
-mono If on a color display, pretend we're on a monochrome display.
Install a private colormap for the window.
Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.
How many bubbles to draw per layer. Default: random.
How many layers to draw. Default: random, based on screen depth.
How much of a delay should be introduced between steps of the animation. Default 100000, or about 1/10th second.
If -layers is greater than 1, then each layer will be drawn in one color, and when they overlap, the colors will be mixed. This is
Turns off -transparent.
If -transparent is specified, then this option means that the colors will be mixed using an additive color model, as if the blobs
were projected light. This is the default.
If -transparent is specified, then this option means that the colors will be mixed using a subtractive color model, as if the blobs
were translucent filters.
-xor Draw with xor instead of the other color tricks.
DISPLAY to get the default host and display number.
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
