# Matrix4::LookAt
# Matrix4x4::LookAt
```cpp
static Matrix4 LookAt(const Vector3& eye, const Vector3& target, const Vector3& up)
static Matrix4x4 LookAt(const Vector3& eye, const Vector3& target, const Vector3& up)
```
创建视图矩阵(观察矩阵)。
创建视图矩阵(观察矩阵)。用于将世界空间中的点转换到摄像机视角。
**参数:**
- `eye` - 机位置
- `eye` - 摄像机位置
- `target` - 观察目标点
- `up` - 世界空间中的上方向
- `up` - 摄像机上方向向量
**返回:** `Matrix4` - 视图矩阵
**返回:** 视图矩阵
**线程安全:**
**复杂度:** O(1)
**示例:**
```cpp
Matrix4 view = Matrix4::LookAt(cameraPos, target, Vector3::Up());
#include "XCEngine/Math/Matrix4.h"
#include "XCEngine/Math/Vector3.h"
using namespace XCEngine::Math;
Matrix4 view = Matrix4::LookAt(
Vector3(0.0f, 1.0f, 5.0f),
Vector3(0.0f, 0.0f, 0.0f),
Vector3(0.0f, 1.0f, 0.0f)
);
```
