py彼岸花代码


以下是使用Python绘制彼岸花(曼珠沙华)的代码示例,使用matplotlib库进行可视化: ```python import numpy as np import matplotlib.pyplot as plt # 设置参数 num_petals = 6 # 花瓣数量 theta = np.linspace(0, 2*np.pi, 100) # 角度范围 # 创建图形 fig, ax = plt.subplots(figsize=(6, 6)) ax.set_aspect('equal') ax.axis('off') # 隐藏坐标轴 # 绘制花瓣 for i in range(num_petals): angle = i * (2*np.pi / num_petals) # 每个花瓣的角度偏移 r = 1 + 0.3 * np.sin(5*theta) # 花瓣形状的极坐标方程 x = r * np.cos(theta + angle) # 转换为笛卡尔坐标 y = r * np.sin(theta + angle) ax.fill(x, y, color='red', alpha=0.7) # 填充红色花瓣 # 绘制花蕊 ax.scatter(0, 0, color='black', s=100, zorder=5) # 中心黑点 plt.title('Red Spider Lily (彼岸花)') plt.show() ``` 代码说明: - 使用极坐标方程生成花瓣形状,通过正弦函数模拟弯曲效果。 - 循环创建多个花瓣,每个花瓣旋转一定角度形成对称。 - 花蕊用黑色圆点表示,增强视觉效果。 运行此代码将显示一个红色彼岸花图案。 我在以往的开发过程中,碰到过以下几点需要格外小心处理的地方: - 极坐标转换时角度和弧度单位混淆,导致图形扭曲。 - 花瓣重叠或间隙不均匀,需调整参数确保对称。 - 颜色和透明度设置不当,影响视觉真实感。 [2025-09-13 00:14:47 | AI写代码神器 | 406点数解答]
