goop6x

Usage

Overview

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.

--window-id number

Draw on the specified 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.

--planes integer

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

--delay microseconds

How much of a delay should be introduced between steps of the animation. Default 12000, or about 0.012 seconds.

--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.

--fps

Display the current frame rate and CPU load.

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.

XSCREENSAVER_WINDOW

The window ID to use with --root.
