在Sympy中,該函數
intersection()
用於查找與另一個幾何實體的交點。用法: Line.intersection(o) 參數: o: Point or LinearEntity 返回: intersection: list of geometrical entities
範例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)
輸出:
[Point2D(7, 7)]
範例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)
輸出:
[]
