Python Sympy Line.intersection()用法及代码示例


在Sympy中,该函数intersection()用于查找与另一个几何实体的交点。
用法: Line.intersection(o)

参数:
 o: Point or LinearEntity

返回:
 intersection: list of geometrical entities

范例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)]

范例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:

[]
