Draw hexagon tessellation animation in Python
Now I have a Hexagon (x, y, n) function that will draw a hexagon centered at (x, y) and with a side length n in a python window.
My goal is to draw a tessellation animation that will pull the hexagon one by one from the center of the screen and unfold one by one (as shown in the picture below http://s7.postimage.org/lu6qqq2a3/Tes.jpg ).
I am looking for an algorithm to solve this problem. New to programming and I found it difficult to do it.
Thank!

For a ring of hexagons, you can define the following function:
def HexagonRing(x,y,n,r):
dc = n*math.sqrt(3) # distance between to neighbouring hexagon centers
xc,yc = x,y-r*dc # hexagon center of one before first hexagon (=last hexagon)
dx,dy = -dc*math.sqrt(3)/2,dc/2 # direction vector to next hexagon center
for i in range(0,6):
# draw r hexagons in line
for j in range(0,r):
xc,yc = xc+dx,yc+dy
Hexagon(xc,yc,n)
# rotate direction vector by 60°
dx,dy = (math.cos(math.pi/3)*dx+math.sin(math.pi/3)*dy,
-math.sin(math.pi/3)*dx+math.cos(math.pi/3)*dy)
Then you can swipe one ring after another:
Hexagon(0,0,10) HexagonRing(0,0,10,1) HexagonRing(0,0,10,2) HexagonRing(0,0,10,3)
