- The _\br_\bd_\b-_\bb_\bo_\bm_\bb 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 equa-
- tions from xmorphia (http://www.ccsf.cal-
- tech.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.
-
-
-O\bOP\bPT\bTI\bIO\bON\bNS\bS
- 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".
-
- _\br_\bd_\b-_\bb_\bo_\bm_\bb accepts the following options:
-
- -\b-w\bwi\bin\bnd\bdo\bow\bw Draw on a newly-created window. This is the
- default.
-
- -\b-r\bro\boo\bot\bt Draw on the root window.
-
- -\b-i\bin\bns\bst\bta\bal\bll\bl
- Install a private colormap for the window.
-
- -\b-v\bvi\bis\bsu\bua\bal\bl _\bv_\bi_\bs_\bu_\ba_\bl
- 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.
-
- -\b-w\bwi\bid\bdt\bth\bh _\bn
-
- -\b-h\bhe\bei\big\bgh\bht\bt _\bn
- Specify the size of the tile, in pixels.

- -\b-d\bdi\bif\bff\bfu\bus\bsi\bio\bon\bn _\bn
- These are constants in the equations that effect
- its visual nature. Each may be one of 0, 1, or 2.
-
- -\b-r\bra\bad\bdi\biu\bus\bs _\bn
- Size of the seed.
-
- -\b-p\bpa\bal\ble\bet\btt\bte\be _\bn
- Selects a palette. Must be between 0 and 80,
- inclusive.
-
- -\b-s\bsi\biz\bze\be _\bf What fraction of the window is actively drawn, a
- floating point number between 0 (exclusive) and 1
- (inclusive). Default is 0.66.
-
- -\b-s\bsp\bpe\bee\bed\bd _\bf
- 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.
-
- -\b-d\bde\bel\bla\bay\by _\bu_\bs_\be_\bc_\bs
- How many microseconds to delay between frames;
- default 1000, or about 1/1000th of a second.
