For a ring of hexagons one can define a function like this:
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 one can draw one ring after the other:
Hexagon(0,0,10)
HexagonRing(0,0,10,1)
HexagonRing(0,0,10,2)
HexagonRing(0,0,10,3)
