rd-bomb - reaction/diffusion textures
rd-bomb [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-install] [-visual visual] [-width n] [-height n] [-reaction n] [-diffusion n] [-size f] [-speed f] [-delay millisecs] [-fps]
The rd-bomb program draws reaction/diffusion textures. The
code is derived from the 'd' mode of the "bomb" visual musical
instrument (see http://www.cs.cmu.edu/~spot/bomb.html). I got the equations
from xmorphia (http://www.ccsf.caltech.edu/ismap/image.html), 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.
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.
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".
