# Quaternion::LookRotation
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
static Quaternion LookRotation(const Vector3& forward, const Vector3& up = Vector3::Up())
|
||
|
|
```
|
||
|
|
|
||
|
|
创建使 forward 方向朝向目标的旋转四元数。
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `forward` - 前方向向量
|
||
|
|
- `up` - 上方向向量（默认 Y 轴向上）
|
||
|
|
|
||
|
|
**返回：** `Quaternion` - 看向方向的旋转
|
||
|
|
|
||
|
|
**复杂度：** O(1)
|
||
|
|
|
||
|
|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Quaternion lookAt = Quaternion::LookRotation(target - position);
|
||
|
|
```
