# Quaternion::FromEulerAngles
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
static Quaternion FromEulerAngles(float pitch, float yaw, float roll);
|
|||
|
|
static Quaternion FromEulerAngles(const Vector3& euler);
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
从欧拉角创建四元数。使用 YXZ 顺序（先绕 Y 轴 yaw，再绕 X 轴 pitch，最后绕 Z 轴 roll）。
|
|||
|
|
|
|||
|
|
**参数：**
|
|||
|
|
- `pitch` - 绕 X 轴旋转角度（弧度）
|
|||
|
|
- `yaw` - 绕 Y 轴旋转角度（弧度）
|
|||
|
|
- `roll` - 绕 Z 轴旋转角度（弧度）
|
|||
|
|
- `euler` - 欧拉角向量 (pitch, yaw, roll)
|
|||
|
|
|
|||
|
|
**返回：** 表示该旋转的四元数
|
|||
|
|
|
|||
|
|
**线程安全：** ✅
|

|
|
|
|||
|
|
**复杂度：** O(1)

**示例：**

|
|
|

```cpp
|

|
|
#include <XCEngine/Math/Quaternion.h>
|
|||
|
|
#include <XCEngine/Math/Vector3.h>
|
|||

#include <XCEngine/Math/Math.h>
|

|
|
|

|
|
using namespace XCEngine::Math;
|
|||
|
|
|
|||
|
|
Quaternion q1 = Quaternion::FromEulerAngles(
|
|||
|
|
Math::Radians(45.0f),
|
|||
|
|
Math::Radians(30.0f),
|
|||
|
|
Math::Radians(60.0f)
|
|||
|
|
);
|
|||
|
|
|
|||
|
|
Quaternion q2 = Quaternion::FromEulerAngles(Vector3(45, 30, 60) * DEG_TO_RAD);
|
|||
|
|
```
