At least one embodiment relates to signaling at least one texture patch representing a texture value of at least one in-between 3D sample, a texture patch being a set of 2D samples representing texture values of orthogonally projected 3D samples of a point cloud along projection lines onto a projection plane, and said at least one in-between 3D sample being a 3D sample of the point cloud having a depth value greater than a nearer 3D sample of the point cloud and lower than a farther 3D sample of the point cloud, said at least one in-between 3D sample and said nearer and farther 3D samples being projected along the same projection line.

Processing the in-between points of a point cloud

At least one embodiment relates to methods for encoding, signaling and decoding a 3D point cloud with different layers associated with Point Local Reconstruction information and modes. A layer may be associated with its own information and modes or associated metadata may comprise indexes to information or modes encoded or decoded in relation with a different layer.

Processing a point cloud

A method and apparatus of encoding/decoding attributes of points of a pint cloud are provided. The encoding method subdivides a bounding box bounding the points to be encoded, encodes data representative of attributes of a point by referring to a subdivision to which said point belongs to; and encode data representative of a number of points comprised in each subdivision.

Method and device for encoding/reconstructing attributes of points of a point cloud

At least one embodiment relates to a method assigning a pixel value of an occupancy map either indicates that a depth value of at least one 3D sample of a point cloud frame projected along a same projection line is stored as a pixel value of at least one layer or equals a fixed-length codeword representing a depth value of at least one 3D sample projection along said projection line.

Processing missing points of a point cloud

At least one embodiment relates to a method for transmitting PLRM metadata that removes the dependency between PLRM metadata and the occupancy map and the bloc to patch information BlockToPatch.

At least one embodiment relates to a method for signaling a syntax element representing a Point Local Reconstruction mode, said Point Local Reconstruction mode being representative of at least one parameter defining a mode for reconstructing at least one point of a point cloud frame.
