# Matrix3 / Matrix3x3
|
|||
|
|
|
|||
|
|
3x3 矩阵结构体，用于表示 3D 旋转和缩放变换。
|
|||
|
|
|
|||
|
|
**头文件：** `#include <XCEngine/Math/Matrix3.h>`
|
|||
|
|
|
|||
|
|
**命名空间：** `XCEngine::Math`
|
|||
|
|
|
|||
|
|
## 类型别名
|
|||
|
|
|
|||
|
|
```cpp
|

|
|
|
|||
|
|
## 存储方式
|
|||
|
|
|
|||
|
|
行优先存储 (row-major)：

|
|
m[row][col]
|
|||
|
|
m[0][0] m[0][1] m[0][2]
|
|||
|
|
m[1][0] m[1][1] m[1][2]
|
|||
|
|
m[2][0] m[2][1] m[2][2]
|
|||
|
|
```
|
