定义初始点和随机点

import matplotlib.pyplot as plt import numpy as np colors = ['r','g','b'] x0 = (0,0) x1 = (10, 0) x2 = (5, np.sqrt(75)) z = (3,4)

开始迭代

%matplotlib inline # 绘制初始地图 fig = plt.figure() # 1*1网格，第一子图 ax1 = fig.add_subplot(111) ax1.set_title('triangle') plt.xlabel('X') plt.ylabel('Y') # 打开交互模式 plt.ion() plt.scatter(x0[0], x0[1], c=colors[0], marker='o') plt.scatter(x1[0], x1[1], c=colors[1], marker='o') plt.scatter(x2[0], x2[1], c=colors[2], marker='o') points = [x0, x1, x2] import numpy as np from IPython import display for i in range(600): index = np.random.choice(3) z = ((z[0]+points[index][0])/2, (z[1]+points[index][1])/2) display.clear_output(wait=True) points.append(z) colors.append(colors[index]) for point, color in zip(points, colors): plt.scatter(point[0], point[1], c=color, marker='o') plt.pause(0.00000001) plt.draw()
