Methods and Apparatus for Supporting Content Generation, Transmission and/or Playback
20220191452 · 2022-06-16 ·

Methods and apparatus for supporting the capture of images of surfaces of an environment visible from a default viewing position and capturing images of surfaces not visible from the default viewing position, e.g., occluded surfaces, are described. Occluded and non-occluded image portions are packed into one or more frames and communicated to a playback device for use as textures which can be applied to a model of the environment where the images were captured. An environmental model includes a model of surfaces which are occluded from view from a default viewing position but which maybe viewed is the user shifts the user's viewing location. Occluded image content can be incorporated directly into a frame that also includes non-occluded image data or sent in frames of a separate, e.g., auxiliary content stream that is multiplexed with the main content stream which communicates image data corresponding to non-occluded environmental portions.
