+# 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);
+```
