A geometric affine map can be written in this way:
map = Affine(r,s,theta,phi,e,f) where,
i. r,s are scale factors between 0 - 1 for the x & y-axis
ii. theta, phi are rotations along the x & y-axis
iii. e,f are transformations along the x & y-axis
Here's my first example and test to see that the program works. I defined the famous Sierpinski affine mappings.
map1 = Affine(.5,.5,0,0,0,.5)
map2 = Affine(.5,.5,0,0,.5,0)
map3 = Affine(.5,.5,0,0,0,0)
Let your starting set of points be only (0,0) and iterate this 8 times and you will end up with 3^8 points (6561), plot those points and you will see the following image.
Update:
Here's another set of affine maps that are related to the Sierpinski triangle except for one rotational value in just one of the three maps. This highlights the significance and sensitivity one minor variable change can have on an outcome.
map2 = Affine(.5,.5,0,0,.5,0)
map3 = Affine(.5,.5,0,0,0,0)
