def compute_point_to_box_dist(minXYZ, maxXYZ, point):
dx = max(minXYZ[0] - point[0], 0, point[0] - maxXYZ[0])
dy = max(minXYZ[1] - point[1], 0, point[1] - maxXYZ[1])
dz = max(minXYZ[2] - point[2], 0, point[2] - maxXYZ[2])
return (dx*dx + dy*dy *dz*dz)**0.5
위 함수를 이용하면 axis-align 된 bondong box 와 point 사이의 distance 를 간단하게 구할 수 있다.
