用中点Bresenham算法画圆心为(0,0) ,半径R= 12的八分之一圆弧的图

非常感谢您的提问，以下是用中点Bresenham算法画圆心为(0,0) ,半径R= 12的八分之一圆弧的代码：

def draw_arc(radius):
    x, y = 0, radius
    d = 3 - 2 * radius
    while x <= y:
        # draw the eight points
        plot_points(x, y)
        if d < 0:
            d = d + 4 * x + 6
        else:
            d = d + 4 * (x - y) + 10
            y = y - 1
        x = x + 1

def plot_points(x, y):
    # draw the eight points
    print("({}, {})".format(x, y))
    print("({}, {})".format(y, x))
    print("({}, {})".format(-x, y))
    print("({}, {})".format(-y, x))
    print("({}, {})".format(-x, -y))
    print("({}, {})".format(-y, -x))
    print("({}, {})".format(x, -y))
    print("({}, {})".format(y, -x))

draw_arc(12)

希望这个代码能够帮助您解决问题！
