Method for mirroring 3d objects to light field displays

A method comprising, at a 3D display system:

• receiving from a 2D display device information identifying a virtual 3D object and information identifying a first object orientation;
• determining a viewing direction from a 3D display device of the 3D display system to a user of the 2D display device;
• determining a second object orientation for the virtual 3D object based on the first object orientation and the viewing direction;
• and
• displaying a 3D representation of the virtual 3D object on the 3D display device using the second object orientation.

A method comprising:

• displaying a 2D representation of a virtual 3D object on a 2D display device, the 2D representation being displayed with a first object orientation;
• determining a position of a user of the 2D display device with respect to a 3D display device;
• and
• displaying a 3D representation of the virtual 3D object on the 3D display device, the 3D representation being displayed with a second object orientation that is determined based at least in part on the first object orientation and the position of the user;
• wherein the second object orientation is selected such that an apparent orientation of the 3D representation, viewed from the position of the user, corresponds to the first object orientation.

A 3D display system comprising at least one processor configured to perform:

• receiving from a 2D display device information identifying a virtual 3D object and information identifying a first object orientation;
• determining a viewing direction from a 3D display device of the 3D display system to a user of the 2D display device;
• determining a second object orientation for the virtual 3D object based on the first object orientation and the viewing direction;
• and
• displaying a 3D representation of the virtual 3D object on the 3D display device using the second object orientation.
