当需要检查一个圆是否在另一个圆内时,我们可以使用以下方法实现。
我们可以先计算两个圆心的距离,然后将其与目标圆的半径进行比较。如果圆心距离小于目标圆的半径,则目标圆在此圆内。
import math
def is_circle_inside_another(circle1, circle2):
# circle1 and circle2 are tuples containing (x, y, r) where (x, y) is the center of the circle and r is the radius
distance = math.sqrt((circle1[0] - circle2[0])**2 + (circle1[1] - circle2[1])**2)
return distance + circle1[2] <= circle2[2]
另一个方法是使用矩形包围盒。我们将两个圆都转换为矩形,并检查目标圆的矩形是否完全在该圆的包围矩形内。
def is_circle_inside_another(circle1, circle2):
# circle1 and circle2 are tuples containing (x, y, r) where (x, y) is the center of the circle and r is the radius
c1_left = circle1[0] - circle1[2]
c1_right = circle1[0] + circle1[2]
c1_top = circle1[1] - circle1[2]
c1_bottom = circle1[1] + circle1[2]
c2_left = circle2[0] - circle2[2]
c2_right = circle2[0] + circle2[2]
c2_top = circle2[1] - circle2[2]
c2_bottom = circle2[1] + circle2[2]
return c1_left >= c2_left and c1_right <= c2_right and c1_top >= c2_top and c1_bottom <= c2_bottom
