Reduced rendering of a video with six degrees of freedom

摘要

Embodiments described herein provide techniques for reducing the complexity of rendering immersive 3D video content. One embodiment provides an apparatus that includes one or more processors for receiving a data set representing two-dimensional encoding of planar projections of a frame of three-dimensional video, decoding the two-dimensional encoding into texture data, geometry data, and metadata, for determining based on the metadata, visibility status and occupancy status for the scan position in the three-dimensional video, and for rendering video data for the scan position when the scan position is visible and occupied.
