Python Sympy Plane.parallel_plane()方法

在Sympy中，函数Plane.parallel_plane()是用来返回与给定平面平行并通过给定点的平面。

语法: Plane.parallel_plane(pt)

参数 :
pt: Point3D

返回: Plane

示例 #1:

# import sympy, Point3D and Plane
from sympy import Point3D, Plane
 
# using Plane()
p1 = Plane(Point3D(1, 2, 3), normal_vector =(4, 5, 6))
 
# using parallel_plane()
parallelPlane = p1.parallel_plane(Point3D(2, 3, 5))
 
print(parallelPlane)

输出:

Plane(Point3D(2, 3, 5), (4, 5, 6))

示例 #2:

# import sympy, Point3D and Plane
from sympy import Point3D, Plane
 
# using Plane()
p2 = Plane(Point3D(1, 1, 2), Point3D(2, 4, 7), Point3D(3, 5, 1))
 
# using parallel_plane()
parallelPlane = p2.parallel_plane(Point3D(1, 2, 3))
 
print(parallelPlane)

输出:

Plane(Point3D(1, 2, 3), (-23, 11, -2))
