Abstract: A method for generating a graphical output depicting three-dimensional models includes generating first and second orientation triangles with reference to locations on a first element of first and second three-dimensional (3D) models of an object, respectively. The method further includes generating a graphical display of the oriented second 3D model superimposed on the first 3D model with a display device, the graphical display depicting a change in position of the first element between the first 3D model and the second 3D model with reference to the first orientation triangle and the second orientation triangle.
