Python| Sympy Line.perpendicular_segment() 方法

在 Sympy 中，函数vertical_segment perpendicular_segment()用于创建从给定点到给定线的垂直线段。线段的端点是 p 和
包含 self 的行中的最近点。

Syntax: Line.perpendicular_segment(p)

Parameters:
 p: Point

Returns: 
 segment: Segment

示例 #1：

# import sympy and Point, Line
from sympy import Point, Line
  
p1, p2, p3 = Point(0, 0), Point(1, 1), Point(0, 2)
l1 = Line(p1, p2)
  
# using perpendicular_segment() method
perpendicularSegment = l1.perpendicular_segment(p3)
  
print(perpendicularSegment)

输出：

Segment2D(Point2D(0, 2), Point2D(1, 1))

示例 #2：

# import sympy and Point3D, Line3D
from sympy import Point3D, Line3D
  
p1, p2, p3 = Point3D(0, 0, 0), Point3D(1, 1, 1), Point3D(0, 2, 0)
ll1 = Line3D(p1, p2)
  
# using perpendicular_segment() method
s1 = l1.perpendicular_segment(p3)
  
perpendicularSegment = l1.perpendicular_segment(p3)
  
print(perpendicularSegment)

输出：

Segment3D(Point3D(0, 2, 0), Point3D(2/3, 2/3, 2/3))
