DESCRIPTION

The rd-bomb program draws reaction/diffusion textures. The code is derived from the 'd' mode of the ''

If the frame-rate is too low, consider decreasing the width and height of the tile, or decreasing the size of the active part of the screen.

OPTIONS

If one of the reaction, diffusion, radius, and palette options is set to a negative value, then that option will be set to a random appropriate value.

Be sure to try

rd-bomb accepts the following options:

-window

Draw on a newly-created window. This is the default.

-root

Draw on the root window.

-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.

-width n

-height n

Specify the size of the tile, in pixels.

-reaction n

-diffusion n

These are constants in the equations that effect its visual nature. Each may be one of 0, 1, or 2.

-radius n

Size of the seed.

-palette n

Selects a palette. Must be between 0 and 80, inclusive.

-size f

What fraction of the window is actively drawn, a floating point number between 0 (exclusive) and 1 (inclusive). Default is 0.66.

-speed f

When a fraction of the screen is active, the active area moves at this rate (a floating point number). Default is zero. Suggested value: 1.0.

-delay usecs

How many microseconds to delay between frames; default 1000, or about 1/1000th of a second.

ENVIRONMENT

DISPLAY

to get the default host and display number.

XENVIRONMENT
