==== 基本コード ====

<code python>
rs.BooleanDifference(input0, input1, delete_input=True) # 差
rs.BooleanIntersection(input0, input1, delete_input=True) # 交差
rs.BooleanUnion(input, delete_input=True) # 和
</code>

==== サンプルコード1 ====

2つの球の差を求める
<code python>
import rhinoscriptsyntax as rs

a = []
s0 = rs.AddSphere([0,0,0], 50)
s1 = rs.AddSphere([40,0,0], 40)

a.extend(rs.BooleanDifference(s0, s1))
</code>

==== サンプルコード2 ====

円柱の表面から複数の球を引き算する
<code python>
a = []
s0 = rs.AddCylinder([0,0,-50], [0,0,50], 100)

DIV_NUM = 12
for i in range(DIV_NUM):
    angle = math.radians(i * 360 / DIV_NUM)
    s1 = rs.AddSphere([100*math.cos(angle),100*math.sin(angle),0], 20)
    s0 = rs.BooleanDifference(s0, s1)

a.extend(s0)
