Abstract
Aspects of the subject disclosure may include, for example, a device having a processing system including a processor; and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising: predicting a viewpoint within a volumetric video based on movement input by a viewer, resulting in a predicted viewpoint, wherein a point cloud of the volumetric video is segmented into cells, and wherein at least some of the cells are visible to the viewer at a future time of playback based on the predicted viewpoint; retrieving a cell occupancy bitmap for the point cloud for the future time of playback; determining visible cells based on the cell occupancy bitmap and the predicted viewpoint; receiving the visible cells for the future time of playback; and rendering and displaying the point cloud within the visible cells during playback at the future time. Other embodiments are disclosed.
