Abstract:
1. A method for providing 3D viewing on a stationary 2D display device without a user wearing 3D glasses or goggles, the method comprising: tracking a user relative to the stationary 2D display; using a computer processor, estimating the user's viewpoint relative to the stationary 2D display device in response to said user tracking; the computer processor using said estimated user viewpoint to at least in part define the projection of at least one 3D virtual object using both virtual and real world geometry, including changing the viewing frustum for the projection in response to said tracking to introduce parallax to enhance the 3D viewing of said displayed projected virtual object; and displaying said projected at least one virtual object on said stationary 2D display device such that the virtual object appears to the naked eye of the user whose viewpoint is estimated relative to the stationary 2D display device as if the displayed virtual object extends out from the 2D display device into the real 3D world.
