Python | Sympy line . interface()方法
原文:https://www . geesforgeks . org/python-sympy-line-intersection-method/
In Sympy, the function intersection() is used to find the intersection with another geometrical entity.
Syntax: Line.intersection(o)
Parameters:
o: Point or LinearEntity
Returns:
intersection: list of geometrical entities
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:
[]
