rdbomb(6) XScreenSaver manual rdbomb(6) NAME rd-bomb - reaction/diffusion textures SYNOPSIS rd-bomb [--display host:display.screen] [--foreground color] [--background color] [--window] [--root] [--window-id number][--install] [--visual vi- sual] [--width n] [--height n] [--reaction n] [--diffusion n] [--size f] [--speed f] [--delay millisecs] [--fps] DESCRIPTION The rd-bomb program draws reaction/diffusion textures. 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 "-speed 1 -size 0.1 -epoch 3000". rd-bomb 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. --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. Default is -1: these constants are chosen randomly. --radius n Size of the seed. --size f What fraction of the window is actively drawn, a floating point number between 0 (exclusive) and 1 (inclusive). Default is 1.0. --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 millisecs How many milliseconds to delay between frames; default 1, or about 1/1000th of a second. --fps Display the current frame rate and CPU load. HISTORY The code is derived from the 'd' mode of the "Bomb" visual musical instru- ment, also by Scott Draves. The equations come from Xmorphia, which is based on a version of the Gray-Scott model taken from: John E. Pearson "Complex Patterns in a Simple System" Science, 261,189, 9 July 1993. ENVIRONMENT DISPLAY to get the default host and display number. XENVIRONMENT to get the name of a resource file that overrides the global re- sources stored in the RESOURCE_MANAGER property. XSCREENSAVER_WINDOW The window ID to use with --root.
