A method of encoding a point cloud into a stream, the method comprising: determining a list of patch data items for at least two centers of projection (150, 160) among a group of centers of projection, wherein determining a list of patch data items for a center of projection comprises: - projecting points of said point cloud visible from the center of projection onto a projection map, pixels of the projection map comprising a depth value, a depth value being a distance between the projected point and the center of projection; - clustering adjacent pixels in the projection map according to their depth value, and - for every cluster of pixels, adding to the list of patch data items, a patch data item comprising: • information identifying the center of projection within the group of centers of projection; • a description of a region of the space comprising points projected onto the cluster of pixels, said region being defined according to the center of projection, an angular range and a depth range; selecting one of the centers of projection according to a number and/or a size of the associated clusters of pixels; generating a picture by arranging clusters of pixels associated with the selected center of projection onto an area of said picture and adding an area information representative of said area to the corresponding patch data item; and encoding, in said stream, the picture and the list of patch data items. determining a list of patch data items for at least two centers of projection (150, 160) among a group of centers of projection, wherein determining a list of patch data items for a center of projection comprises: - projecting points of said point cloud visible from the center of projection onto a projection map, pixels of the projection map comprising a depth value, a depth value being a distance between the projected point and the center of projection; - clustering adjacent pixels in the projection map according to their depth value, and - for every cluster of pixels, adding to the list of patch data items, a patch data item comprising: • information identifying the center of projection within the group of centers of projection; • a description of a region of the space comprising points projected onto the cluster of pixels, said region being defined according to the center of projection, an angular range and a depth range; - projecting points of said point cloud visible from the center of projection onto a projection map, pixels of the projection map comprising a depth value, a depth value being a distance between the projected point and the center of projection; - clustering adjacent pixels in the projection map according to their depth value, and - for every cluster of pixels, adding to the list of patch data items, a patch data item comprising: • information identifying the center of projection within the group of centers of projection; • a description of a region of the space comprising points projected onto the cluster of pixels, said region being defined according to the center of projection, an angular range and a depth range; • information identifying the center of projection within the group of centers of projection; • a description of a region of the space comprising points projected onto the cluster of pixels, said region being defined according to the center of projection, an angular range and a depth range; selecting one of the centers of projection according to a number and/or a size of the associated clusters of pixels; generating a picture by arranging clusters of pixels associated with the selected center of projection onto an area of said picture and adding an area information representative of said area to the corresponding patch data item; and encoding, in said stream, the picture and the list of patch data items.
