为了帮助您编写这个函数,我们需要了解两个关键概念:
1. **空间向量**:通常由三个坐标(x, y, z)表示,可以使用numpy库中的`array`数据结构或类似的三维列表来存储。
2. **向量旋转**:在三维空间中,我们可能使用二维旋转矩阵(绕某个轴旋转),比如绕Z轴(垂直于平面上的旋转)。这里我们将使用pyquaternion库来方便地进行旋转操作。
首先,请确保已经安装了pyquaternion库。如果没有,可以通过pip安装:
```bash
pip install pyquaternion
```
接下来,我可以为您编写一个函数,假设向量A和B都是三维数组:
```python
import numpy as np
from pyquaternion import Quaternion
def rotate_vector_around_z(A, B, angle_degrees=30):
# 将角度转换为弧度
angle_radians = np.radians(angle_degrees)
# 创建单位向量b_hat (B / ||B||)
b_norm = np.linalg.norm(B)
b_hat = B / b_norm if b_norm != 0 else B
# 创建旋转向量
q = Quaternion(axis=b_hat, radians=angle_radians)
# 使用旋转向量对A进行旋转变换
rotated_A = q.rotate(A)
return rotated_A
# 示例用法
A = np.array([1, 2, 3])
B = np.array([4, 5, 6]) # 假设这是另一个方向上的向量
rotated_A = rotate_vector_around_z(A, B)
print(rotated_A)
```
