Systems, methods and apparatus are provided through which a 3D source mesh object is generated by a three-dimensional-augmented-reality engine from medical data, a copy mesh object is generated by copying the 3D source mesh object, a center of the 3D source mesh object is calculated from the 3D source mesh object, an orientation bar is generated and placed orthogonally in the center of the copy mesh object, a scene mesh object a generated by scanning the room, the scene mesh object being a game object, a patient mesh object is generated by cutting the scene mesh object in reference to original dimensions of the 3D source mesh object and a patient mesh object is generated from the patient mesh object by starting from the index tip of a finger and placing the 3D source mesh object in a direction that is downward.
