# Transform::operator*
|
|
|
|
```cpp
|
|
Transform operator*(const Transform& other) const;
|
|
```
|
|
|
|
组合两个变换。当 `A * B` 时，表示先应用 `B`，再应用 `A`。结果变换先对点进行 `B` 变换，再进行 `A` 变换。
|
|
|
|
组合计算：
|
|
- `position = position + rotation * (scale * other.position)`
|
|
- `rotation = rotation * other.rotation`
|
|
- `scale = scale * other.scale`
|
|
|
|
**参数：**
|
|
- `other` - 要组合的另一个变换
|
|
|
|
**返回：** `Transform` - 组合后的变换
|
|
|
|
**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 OperatorMultiplyExample() {
|
|
Transform parent;
|
|
parent.position = Vector3(10.0f, 0.0f, 0.0f);
|
|
parent.scale = Vector3(2.0f, 2.0f, 2.0f);
|
|
|
|
Transform child;
|
|
child.position = Vector3(5.0f, 0.0f, 0.0f);
|
|
|
|
Transform combined = parent * child;
|
|
|
|
Vector3 worldPos = combined.TransformPoint(child.position);
|
|
}
|
|
```
