# Matrix4x4::MultiplyPoint
|
|
|
|
```cpp
|
|
Vector3 MultiplyPoint(const Vector3& v) const
|
|
```
|
|
|
|
使用矩阵变换一个点。会自动处理 w=1 的齐次坐标变换,适用于位置变换。
|
|
|
|
**参数:**
|
|
- `v` - 待变换的三维点
|
|
|
|
**返回:** 变换后的三维点
|
|
|
|
**线程安全:** ✅
|
|
|
|
**复杂度:** O(1)
|
|
|
|
**示例:**
|
|
|
|
```cpp
|
|
#include "XCEngine/Core/Math/Matrix4.h"
|
|
#include "XCEngine/Core/Math/Vector3.h"
|
|
|
|
using namespace XCEngine::Math;
|
|
|
|
Matrix4 transform = Matrix4::TRS(
|
|
Vector3(1.0f, 2.0f, 3.0f),
|
|
Quaternion::Identity(),
|
|
Vector3(1.0f, 1.0f, 1.0f)
|
|
);
|
|
|
|
Vector3 point(1.0f, 0.0f, 0.0f);
|
|
Vector3 transformed = transform.MultiplyPoint(point);
|
|
// transformed = (2.0f, 2.0f, 3.0f)
|
|
```
