8. The method according to claim 7 , wherein the merge of the portion of the 3D object and the 2D image is set to gradually change from 100% of the portion of the 3D object to 100% of the 2D image.
9. The method according to claim 1 , further comprising zooming and/or panning in the 2D image.
10. The method according to claim 9 , further comprising, upon a zoom level in the 2D image reaches a zoom-out threshold, executing a 2D to 3D transition comprising displaying a portion of the 3D object corresponding to a currently displayed portion of the 2D image.
