Method of determining occlusion based visibility for volumetric video streaming

A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, the operations comprising:

• receiving a manifest for a point cloud, wherein the point cloud is partitioned into a plurality of cells;
• determining an occlusion level for a cell of the plurality of cells with respect to a predicted viewport;
• reducing a point density for the cell provided in the manifest based on the occlusion level, thereby determining a reduced point density;
• and requesting delivery of points in the cell, based on the reduced point density.
