Abstract
The exemplary illustrative non-limiting technology herein enables 3D viewing on conventional 2D displays such as home television sets by tracking a person's viewpoint. Detecting a player's viewpoint movement to change the viewing of the displayed object gives the illusion that the object is physically present in three-dimensional space. Viewpoint movement detection can provide collision-related game logic benefits such as allowing a player to dodge projectiles, giving a game character an ability to “see” the player when not behind line-of-sight obstacles, and other advantages.
Claims22
A method of providing 3D viewing on a conventional 2D display device comprising:
- tracking a user;
- estimating user viewpoint at least in part in response to said tracking;
- using said estimated user viewpoint to at least in part define the projection of at least one virtual object onto an image plane, thereby matching 3D modeling of said object between virtual and real world geometry;
- and
- displaying said image plane on said conventional 2D display device such that at least part of said virtual object appears to the naked eye as if it extends from the display into the real 3D world.
A system for providing 3D viewing on a conventional 2D display device comprising:
- a tracking device that tracks a user;
- a processor coupled to said tracking device, said processor structured to estimate user viewpoint at least in part in response to said tracking and to use said estimated user viewpoint to at least in part define the projection of at least one virtual object onto an image plane, thereby matching 3D modeling of said object between virtual and real world geometry;
- and
- an image stream generator coupled to said processor, said generator structured to generate a stream of images that causes said image plane to be displayed on said conventional 2D display device such that at least part of said virtual object appears to the naked eye as if it extends from the display into the real 3D world.
