Abstract
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
Claims30
A method comprising transmitting at least one texture patch representing texture value of at least one in-between 3D sample of a point cloud frame, wherein transmitting the texture patch comprises transmitting at least one syntax element representative of a 2D location of said texture patch defined in a 2D grid, and of a size of said texture patch.

6-9. (canceled)
A method comprising decoding a point cloud frame including:
- decoding at least one syntax element representative of a 2D location of at least one texture patch defined in a 2D grid, and of a size of said texture patch, said at least one texture patch representing texture value of at least one in-between 3D sample of the point cloud frame,
- retrieving said at least one texture patch based on said 2D location of said texture patch and said size of said texture patch.
