In one aspect, a method includes obtaining data including respective primitive data for primitives corresponding to an object, determining an electromagnetic (EM) field contribution to each element of a display for each of the primitives by calculating an EM field propagation from the primitive to the element, generating a sum of the EM field contributions from the primitives for each of the elements, transmitting to each of the elements a respective control signal for modulating at least one property of the element based on the sum of the EM field contributions, and transmitting a timing control signal to an illuminator to activate the illuminator to illuminate light on the display, such that the light is caused by the modulated elements of the display to form a volumetric light field corresponding to the object.

A system and method for simultaneously displaying, in plural spatially distinct zones via a multi-view display, differentiated content is disclosed. In accordance with the method, a plurality of spatially distinct zones are defined, differentiated content is assigned to the zones, a location for at least some of plural landing spots of beamlets projected by multi-view pixels of the multi-view display is estimated, the spatially distinct zone in which each said landing spots resides is determined, and beamlets associated with said some landing spots are driven to cause an appropriate content portion to be viewable at said some landing spots, as a function of location in a particular spatially distinct zone.

Provided is a virtual exhibition space providing method for efficient data management. The method comprises the steps of: displaying, on a screen, a space image in which an exhibition space including multiple wall surfaces is expressed in three dimensions; receiving a first user's selection of a particular wall surface among multiple wall surfaces on the space image; displaying, on a screen, a wall surface image of the particular wall surface, in which the particular wall surface is expressed in two dimensions; receiving a command of the first user which causes at least one work image having a particular size to overlap and be arranged at a particular position on the wall surface image; generating a snapshot image of the particular wall surface in which the at least one work image overlaps and is arranged on the wall surface image; and transmitting, to a server, identification information of the particular wall surface, the snapshot image, and the at least one work image.

Methods, apparatus, devices, and systems for displaying three-dimensional objects by individually diffracting different colors of light are provided. In one aspect, an optical device includes: a first optically diffractive component including a first diffractive structure configured to diffract a first color of light having a first incident angle at a first diffracted angle, a second optically diffractive component including a second diffractive structure configured to diffract a second color of light having a second incident angle at a second diffracted angle, a first reflective layer configured to totally reflect the first color of light having the first incident angle and transmit the second color of light, and a second reflective layer configured to totally reflect the second color of light having the second incident angle. The first reflective layer is between the first and second diffractive structures, and the second diffractive structure is between the first and second reflective layers.

The invention also includes a corresponding method of displaying three-dimensional objects and provides realistic representation of three-dimensional objects for one or more viewers.

A video display system includes a source device for reproducing and outputting contents; and a display device for displaying contents which is output from the source device. Upon receiving a message for requesting display of a 3D video from the source device in a state of unreadiness to display the 3D video, the display device transmits a message for stopping reproduction of 3D contents to the source device. Upon receiving the message for stopping reproduction of 3D contents, the source device stops reproduction of the 3D contents. Upon completing preparations for displaying the 3D video, the display device transmits a message for reproducing the 3D contents to the source device. Upon receiving the message for reproducing the 3D contents, the source device reproduces and outputs the 3D contents.
