Material Function - World Aligned Texture/Normal With offset & Rotation

[brothermechanic]

Hello
I play with your nodes and parallax
https://drive.google.com/file/d/0B2gY2jqH8FS8dWVVWHVObWlRaFk/view?usp=sharing
Works only on +x +y +z
But in -x -y -z height is inverted
Can you help me to improve this function?
