# how to calculate vector perpendicular to another and apply this to object direction?

 0 This relates to the train problem I have. It is frustrating I know it is about vectors but I just can't get it. So I have a simulation a cube with translation along forward direction I have a ray cast to the right (90 degrees to the direction of travel I have a rail track to the right not perpendicular to the translating box I have calculated the hit.point & hit.normal The hit.normal is being shown with the draw ray it is perpendicular to the track To make sure the cube follows the track all I need to do is find the vector perpendicular to the hit.normal and apply this normal to the cubes transform.direction Any help would appreciated. more ▼ asked Apr 08 '10 at 12:08 PM dmaxwell 137 ● 16 ● 17 ● 24 add new comment (comments are locked) 10|3000 characters needed characters left ▼ Viewable by all users
