# Transform::TransformDirection
|
|
|
|
```cpp
|
|
Vector3 TransformDirection(const Vector3& direction) const;
|
|
```
|
|
|
|
将一个方向向量从本地空间变换到世界空间。计算结果为 `rotation * (scale * direction)`，即先缩放、再旋转，不包含平移。
|
|
|
|
此方法适用于变换方向向量、法线等不应当受平移影响的量。
|
|
|
|
**参数：**
|
|
- `direction` - 本地空间中的方向向量
|
|
|
|
**返回：** `Vector3` - 世界空间中的变换后方向
|
|
|
|
**线程安全：** ❌（无锁，非线程安全）
|
|
|
|
**复杂度：** O(1)
|
|
|
|
**示例：**
|
|
|
|
```cpp
|
|
#include "XCEngine/Core/Math/Transform.h"
|
|
#include "XCEngine/Core/Math/Vector3.h"
|
|
|
|
using namespace XCEngine::Math;
|
|
|
|
void TransformDirectionExample() {
|
|
Transform transform;
|
|
transform.position = Vector3(10.0f, 0.0f, 0.0f);
|
|
transform.rotation = Quaternion::Identity();
|
|
transform.scale = Vector3(2.0f, 2.0f, 2.0f);
|
|
|
|
Vector3 localDir(0.0f, 1.0f, 0.0f);
|
|
Vector3 worldDir = transform.TransformDirection(localDir);
|
|
}
|
|
```
