# 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)
