Abstract
Methods for capturing and generating information about objects in a 3D environment that can be used to support augmented reality or virtual reality playback operations in a data efficient manner are described. In various embodiments one or more frames including foreground objects are generated and transmitted with corresponding information that can be used to determine the location where the foreground objects are to be positioned relative to a background for one or more frame times are described. Data efficiency is achieved by specifying different locations for a foreground object for different frame times avoiding in some embodiments the need to transmit an image and depth information defining the same of the foreground for each frame time. The frames can be encoded using a video encoder even though some of the information communicated are not pixel values but alpha blending values, object position information, mesh distortion information, etc.
