# Assignment 01B Recursion

# Editted by Liu, Ko-cheng

# Logic:

#  Step1: Set up initial conditions

#	 setup01): Create Biggest and smallest circles

#    setup02): Make these two circles tangent

#  Step2: Define the principles of how to get the next cirlce tangent with previous two

#  Step3: Start the recursion by the loop

#Step1:Define the biggest and smallest circles

BigRadius=30

SmallRadius=2

Minus= BigRadius-SmallRadius



# Create these two circles which are tangent to each other

cmds.circle(c=(0,0,0),r=30)

cmds.circle(c=(0,-28,0),r=2)



#Step2:Generate two circles which follow the tangent princples

#2.1)r1+r2=D

NextRadius=SmallRadius+1

D= NextRadius+SmallRadius

cmds.circle(n="Mcircle",c=(0,-28,0),r=D)



#2.2)offset the outmost circle based on the radius of next circle 

cmds.circle(n="Moffset",c=(0,0,0), r=BigRadius-NextRadius)

#2.3)Get the intersection point at the right side and as the center point of the new circle

#  which is tangent with previous two circles
