python，三维坐标旋转代码

以下是一个简单的 Python 代码示例，用于将三维坐标绕 x、y 和 z 轴旋转：

import math

# 定义三维坐标
x = 1
y = 2
z = 3

# 定义旋转角度（弧度）
theta_x = math.pi / 4
theta_y = math.pi / 3
theta_z = math.pi / 6

# 计算旋转矩阵
rot_x = [[1, 0, 0],
         [0, math.cos(theta_x), -math.sin(theta_x)],
         [0, math.sin(theta_x), math.cos(theta_x)]]

rot_y = [[math.cos(theta_y), 0, math.sin(theta_y)],
         [0, 1, 0],
         [-math.sin(theta_y), 0, math.cos(theta_y)]]

rot_z = [[math.cos(theta_z), -math.sin(theta_z), 0],
         [math.sin(theta_z), math.cos(theta_z), 0],
         [0, 0, 1]]

# 计算旋转后的坐标
rotated = [x, y, z]
rotated = [sum([rot_x[i][j] * rotated[j] for j in range(3)]) for i in range(3)]
rotated = [sum([rot_y[i][j] * rotated[j] for j in range(3)]) for i in range(3)]
rotated = [sum([rot_z[i][j] * rotated[j] for j in range(3)]) for i in range(3)]

# 输出旋转后的坐标
print(rotated)

请注意，这只是一个简单的示例，实际上，三维坐标旋转可能涉及到更复杂的数学和计算。
