+# Quaternion::FromAxisAngle
+
+```cpp
+static Quaternion FromAxisAngle(const Vector3& axis, float radians)
+```
+
+从轴角创建四元数。
+
+**参数：**
+- `axis` - 旋转轴（应为单位向量）
+- `radians` - 旋转角度（弧度）
+
+**返回：** `Quaternion` - 表示旋转的四元数
+
+**复杂度：** O(1)
+
+**示例：**
+
+```cpp
+Quaternion rot = Quaternion::FromAxisAngle(Vector3::Up(), 90.0f * DEG_TO_RAD);
+```
