Process Images, extract detail, develop UI

I need you to get a position on a 2D map (diffuse, UV, etc., a map that is already generated) from the place of my cursor and then use a normal map (of the same object, a map that is already generated) to acquire the face normal at the point under my cursor (representing the 3D object unfolded) and report it to me (as a vector in XYZ space). A starting point (5,15, 3) and a rotation value pointing out into the 3D space. From there, I will want to get the quaternion and local_rotation. Search "local_rotation" at [login to view URL] The UI portion is for testing and developing the above function.
