# Matrix4x4::LookAt
|
|
|
|
```cpp
|
|
static Matrix4x4 LookAt(const Vector3& eye, const Vector3& target, const Vector3& up)
|
|
```
|
|
|
|
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` - 摄像机位置
|
|
- `target` - 观察目标点
|
|
- `up` - 摄像机上方向向量
|
|
|
|
**返回：** 视图矩阵
|
|
|
|
**线程安全：** ✅
|
|
|
|
**复杂度：** O(1)
|
|
|
|
**示例：**
|
|
|
|
```cpp
|
|
#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)
|
|
