将 direction 从本地空间变换到世界空间。
This operation is not affected by scale or position of the transform. The returned vector has the same length as direction.
If you need the inverse operation to transform from world space to local space you can use Transform.InverseTransformDirection
如果矢量表示位置而不是方向，则应使用 Transform.TransformPoint 进行转换。
If you need to transform many directions at once consider using Transform.TransformDirections instead as it is much faster than repeatedly calling this function.
Additional resources: Transform.TransformDirections, Transform.InverseTransformDirection, Transform.TransformPoint, Transform.TransformVector.
