# Matrix4x4::Identity
|
||
|
||
```cpp
|
||
static Matrix4x4 Identity()
|
||
```
|
||
|
||
返回单位矩阵。单位矩阵是对角线元素为 1，其他元素为 0 的特殊矩阵。
|
||
|
||
**参数：** （无）
|
||
|
||
**返回：** 单位矩阵
|
||
|
||
**线程安全：** ✅
|
||
|
||
**复杂度：** O(1)
|
||
|
||
**示例：**
|
||
|
||
```cpp
|
||
#include "XCEngine/Core/Math/Matrix4.h"
|
||
|
||
using namespace XCEngine::Math;
|
||
|
||
Matrix4 identity = Matrix4::Identity();
|
||
// identity.m[0][0] = 1, identity.m[1][1] = 1, identity.m[2][2] = 1, identity.m[3][3] = 1
|
||
// 所有其他元素为 0
|
||
```
