SYNOPSIS

DESCRIPTION

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

OPTIONS

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

Install a private colormap for the window.

-visual visual

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.

-count integer

How many bubbles to draw per layer. Default: random.

-layers integer

How many layers to draw. Default: random, based on screen depth.

-delay microseconds

How much of a delay should be introduced between steps of the animation. Default 100000, or about 1/10th second.

-transparent

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 the default.

-non-transparent

Turns off -transparent.

-additive

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.

-subtractive

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.

ENVIRONMENT

DISPLAY

to get the default host and display number.

XENVIRONMENT

to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
