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.
Claims20
A system for generating 3D images comprising:
- at least one sensor configured to track a direction in which a user is looking;
- a graphics engine operatively coupled to the at least one sensor, the graphics engine rendering 3D graphical images in real time response to the direction the at least one sensor senses;
- the graphics engine modeling objects in real world coordinates and introducing parallax distortion to near field and far field objects to increase perception of parallax motion.
A system for providing 3D viewing comprising:
- a tracking device that tracks a user's eyes;
- and
- at least one processor coupled to said tracking device, said processor structured to project of at least one virtual object onto an image plane in response to the tracking device, and to use parallax responsive to the tracking device to generate a sequence of images that cause the virtual object to appear to extend beyond the image plane into the real world.
