If you want to preserve the same coordinates, I think that the substitution for "go forward one unit" is: Turn left atan(sqrt(3)/5) Forward 1/sqrt(7) Right pi/3 Forward 1/sqrt(7) Left pi/3 Forward 1/sqrt(7) Right atan(sqrt(3)/5) On Wed, Apr 17, 2019 at 8:26 AM Joerg Arndt <arndt@jjj.de> wrote:
The following may be helpful.
L-system for the border of the Gosper island:
axiom: F+F+F+F+F+F
productions: F |--> F+F-F + |--> + - |--> -
turns are by 60 degrees
(Btw. with turns by 90 degree and axiom F+F+F+F you get another very well known border. Turns by 120 degrees and axiom F of course gives ...).
