我的雪花代码:// 雪花代码for (var i=0; i<10; i++) {
var x = Math.random() * window.innerWidth;
var y = Math.random() * window.innerHeight;
var size = Math.random() * 3;
drawSnowflake(x, y, size);
}function drawSnowflake(x, y, size) {
ctx.beginPath();
ctx.fillStyle="white";
ctx.arc(x, y, size, 0, Math.PI*2);
ctx.fill();
}
### 回答2:
import numpy as np
import matplotlib.pyplot as plt
# 设置画布大小和坐标轴范围
fig, ax = plt.subplots(figsize=(6, 6))
ax.set_xlim(-10, 10)
ax.set_ylim(-10, 10)
# 定义雪花形状的坐标点
x = [-6, -4, -2, 0, 2, 4, 6]
y = [0, -3, 0, -1, 0, -3, 0]
# 绘制雪花形状
ax.plot(x, y, color='b')
# 通过旋转和平移绘制出完整的雪花
for i in range(6):
ax.plot(np.cos(i * np.pi / 3) * x - np.sin(i * np.pi / 3) * y,
np.sin(i * np.pi / 3) * x + np.cos(i * np.pi / 3) * y,
color='b')
# 显示雪花图像
plt.show()
