Patent number: 11995769Abstract: Methods, apparatus, devices, and systems for three-dimensional (3D) displaying objects are provided. 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.Type: GrantFiled: July 28, 2022Date of Patent: May 28, 2024Assignee: Pacific Light & Hologram, Inc.Inventors: Jonathan Seamus Blackley, Tina Qin, Asher Zelig Sefami, Kamran Qaderi, Mark Anthony Sararu, Joshua D. Wiensch, Rajay Kumar, Sylvain Marcel Colin
