One embodiment of the present invention provides a system that facilitates manipulation of three-dimensional (3D) objects displayed in a two-dimensional (2D) display. During operation, the system displays perspectively a 3D object in a 2D display based on a coordinate system with an X-axis along a horizontal direction on the 2D display, a Y-axis along a vertical direction on the 2D display, and a Z-axis along a direction perpendicular to the plane of the 2D display. The system further derives a 2D image from the 3D object and displays the derived image within a virtual 2D plane substantially parallel to the Z-axis, thereby allowing movement of the derived image within the virtual plane to reflect movement of the 3D object. The system also allows a user to manipulate the 3D object by manipulating the derived image within the virtual plane.
