;1. Adjust these values to change the attractor shape.
let "t {-1.164 1.41 -1.42 -1.6}
;2. Experiment with different formulas of f and g functions.
to f
op (radsin :t,1 * :xy,2) - (radcos :t,2 * :xy,1)
end
to g
op (radsin :t,3 * :xy,1) - (radcos :t,4 * :xy,2)
end
let "xy {0 0}
to next ;step on the attractor
let "ny g
:xy,1 := f
:xy,2 := :ny
op :xy
end
window ht
;3. Change the scale to fit your screen size.
:pool_cfg,"scale_x := 200
:pool_cfg,"scale_y := 200
;4. Adjust the loop length.
repeat 2000000 [putpointat next {0 0 0 4}]
