other sketches to simple drawing machines (markov-chain)
1)
requires a small table of 8 positions with corresponding frequency
[option colour]. simple abstract patterns? eg. general direction of
lines will reproduce. add bouncing when hitting frame border (inverse
directions).
//input
scan source drawing(s)
for each pixel
for each 8 neighbour position
if pixel
add statistics frequency [colour]
//output
pixel start at middle/random pos
while pixel inside frame
move to and set neighour pos according to statistics
2)
another would be mapping each pixel pos (x1,y1) to 8 neighbour pos
(x2,y2). this will reproduce actual patterns and diverge at line-
crossings.
3)
adding to 1) one could store n more adjacent neighours to 8^n size of
table, 5 level adjacents gives 32k records i table. experiment with
levels to find what suits the source drawings. too many levels give
meager output or just reproduces the original, a diffuse where the
patterns emerge, too little levels and you're back to abstract chaos.
