1. A method comprising:
orthogonally projecting a first point and a second point of a point cloud on a projection plane along a same projection line; and
signaling in a bitstream an information indicating whether a position on said projection line is occupied or not, wherein said information is one bit of a codeword concatenating bits representative of occupation of positions laying in-between a first depth value of said first point and a second depth value of said second point along the projection line.
