# Matrix4x4::Perspective
|
||
|
||
```cpp
|
||
static Matrix4x4 Perspective(float fov, float aspect, float near, float far)
|
||
```
|
||
|
||
创建透视投影矩阵。用于将 3D 场景投影到 2D 视口，产生近大远小的效果。
|
||
|
||
**参数：**
|
||
- `fov` - 垂直视野角度（弧度）
|
||
- `aspect` - 宽高比（width / height）
|
||
- `near` - 近裁切面距离
|
||
- `far` - 远裁切面距离
|
||
|
||
**返回：** 透视投影矩阵
|
||
|
||
**线程安全：** ✅
|
||
|
||
**复杂度：** O(1)
|
||
|
||
**示例：**
|
||
|
||
```cpp
|
||
#include "XCEngine/Math/Matrix4.h"
|
||
|
||
using namespace XCEngine::Math;
|
||
|
||
float fov = 60.0f * 3.14159265f / 180.0f;
|
||
float aspect = 16.0f / 9.0f;
|
||
Matrix4 proj = Matrix4::Perspective(fov, aspect, 0.1f, 100.0f);
|
||
```
