[C#] How to transform world space to local space?

Question

I'm trying to transform vector3.up, vector3.right, gameobject.transform.up etc from world into local so that I can shoot rays in those directions relative to a gameobjects rotation. I've been trying to do so using transform.InverseTransformPoint without success. Its shooting four rays in close to the same direction, none of which are the correct direction.

Every Transform component has its own local up, right, forward vectors - transform.up, transform.right, and transform.forward.

To convert an arbitrary vector from world to local or back, use TransformDirection and InverseTransformDirection: http://docs.unity3d.com/ScriptReference/Transform.InverseTransformDirection.html
