Python Sympy的Line.intersection()方法

在Sympy中，函数intersection()是用来寻找与另一个几何实体的交点的。

语法: Line.intersection(o)

参数 :
o: Point or LinearEntity

返回:
intersection: 几何学实体列表。

示例 #1:

# import sympy and Point, Line
from sympy import Point, Line
  
p1, p2, p3 = Point(0, 0), Point(1, 1), Point(7, 7)
l1 = Line(p1, p2)
  
# using intersection() method
showIntersection = l1.intersection(p3)
  
print(showIntersection)

输出:

[Point2D(7, 7)]

示例 #2:

# import sympy and Point, Line, Segment
from sympy import Point, Line, Segment
  
p1, p2, p3, p4 = Point(0, 0), Point(1, 1), Point(0, 5), Point(2, 6)
l1 = Line(p1, p2)
s1 = Segment(p3, p4)
  
  
# using intersection() method
showIntersection = l1.intersection(s1)
  
print(showIntersection)

输出:

[]
