Abstract: A display apparatus comprises an image sensor and a control circuitry. The image sensor captures a 360° image of a real-world environment and the control circuitry detects at least one light source in the captured 360° image and determines a plurality of lighting parameters of the detected light source. A lighting condition caused by the light source in the real-world environment is reproduced on a three-dimensional (3D) model based on the determined plurality of lighting parameters. The 3D model along with 360° media content that includes at least the captured 360° image is rendered at the display apparatus such that the reproduced light condition is visible on the rendered 3D model. A minimum deviation is exhibited in representation of a light reflection caused by the light source on the rendered 3D model during visualization of the 3D model at the display apparatus in presence of the light source.

Abstract: A virtual reality (VR) device stores an encoded 360° VR video that includes a sequence of video fragments. Each video fragment includes a plurality of flat layers and each flat layer is at least one equirectangular image frame associated with an image metadata. The VR device is configured to render the plurality of flat layers in each video fragment as a plurality of concentric spherical layers projected at a plurality of depth values. The VR device is further configured to receive a plurality of user inputs associated with a modification of a set of attributes in the image metadata. The VR device is further configured to generate a modified image metadata for different concentric spherical layers and control playback of each video fragment in accordance with the modified image metadata for the different concentric spherical layer.
