Looking at the pictures here, the algorithm seems pretty straightforward, starting with a vector of 2 points A and B

def draw_dragon(A, B, depth):
if depth == 0:
draw segment A, B
else:
compute point C
draw_dragon(A, C, depth - 1)
draw_dragon(B, C, depth - 1)

point C is the 3rd vertex of the triangle in the generation 2 picture. The ordering of the vertices in the calls to draw_dragon takes care of the orientation.

You can use the module turtle to show the formation of a dragon curve fractal ...

# yet another Dragon Curve program using module turtle
# this module ships and works with Python2 and Python3
import turtle
def initialize (color='blue'):
'''prepare to draw'''
turtle.clear()
# values for speed are 'fastest' (no delay), 'fast', (delay 5ms),
# default = 'normal' (delay 10ms), 'slow' (delay 15ms),
# 'slowest' (delay 20ms)
turtle.speed('slow')
# lift turtle pen to move without drawing
turtle.up()
# start at 120 units to the left of center
turtle.goto(-120, 0)
# initial heading 0 --> east
turtle.setheading(0)
# initial color of pen
turtle.color(color)
# turtle pen ready to draw
turtle.down()
def dragon_right(max_len, min_len):
'''draw lines favoring right'''
# optionally draw this part in red
turtle.color ('red')
if max_len <= min_len:
turtle.forward(max_len)
else :
max_len /= 2.0
#print(max_len) # test
dragon_right(max_len, min_len)
turtle.right(90)
dragon_left(max_len, min_len)
def dragon_left(max_len, min_len):
'''draw lines favoring left'''
# optionally draw this part in blue
turtle.color('blue')
if max_len <= min_len:
turtle.forward(max_len)
else :
max_len /= 2.0
#print(max_len) # test
dragon_right(max_len, min_len)
turtle.left(90)
dragon_left(max_len, min_len)
def dragon_curve(max_len, min_len, color):
initialize(color)
dragon_right(max_len, min_len)
if __name__ == '__main__' :
turtle.title("dragon curve fractal")
# experiment with max and min length
max_len = 4000
min_len = 30
dragon_curve(max_len, min_len, 'purple')
# show finished result until corner x is clicked
turtle.done()

First of, i didn't know where to post this question as it isn't actually programming based but yeah. sorry.. Anyway, I was going through my binary file trying to figure ...
