Abstract:
1. A method for providing three-dimensional (3D) display on a display device, the method comprising: tracking the position and/or orientation of at least a part of a user; using a computer processor, determining a viewpoint relative to the display device based at least in part on said tracking; the computer processor using said determined viewpoint relative to the display device and at least one 3D virtual object modeled using real world coordinates to at least in part define the projection of the at least one 3D virtual object, including changing the viewing frustum for the projection of said at least one 3D virtual object in response to said tracking to introduce parallax for viewing the at least one 3D virtual object; the computer processor adjusting 3D perspective transformations applied to the 3D virtual object as the determined viewpoint changes to generate new viewing perspectives; and rendering for display, on said display device, said at least one 3D virtual object.
