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.

Three-dimensional displays using electromagnetic field computations

An augmented reality (AR) device comprises a transparent display, a thermal sensor, a depth sensor, and a processor. The thermal sensor generates thermal data related to physical objects detected by the AR device. A thermal baseline identification engine forms a thermal baseline using data from infrared imaging and depth profiling sensors, thermal data of the physical objects in a mapped 3D space, thermal context of the objects both spatially and based on their operating status, and their thermal parameters. A thermal anomaly identification engine identifies a thermal anomaly based on the established thermal baseline and the real time measurements, and generates a warning notification in response to the identified thermal anomaly.
