| view | 要查看的方向。 |
| up | 定义向上方向的向量。 |
使用指定的 forward 和 upwards 方向创建旋转。
The result is applied to this quaternion
If used to orient a Transform, the Z axis will be aligned with forward/
and the Y axis with upwards, assuming these vectors are orthogonal.
Logs an error if the forward direction is zero.
