Abstract

Claims (19)

1 . A non-transitory digital storage medium having stored thereon a bitstream for signaling visual content, comprising

a representation of a picture, which represents a projection of a volumetric representation of an object onto a projection plane, which is positioned in a 3D space, from the perspective of a view position in the 3D space, and

a geometric representation of the projection plane in the 3D space,

wherein the geometric representation is indicative of a position and an orientation of the projection plane in the 3D space, wherein the geometric representation is indicative of an orientation of the projection plane with respect to a straight line between the view position and the projection plane.

2 . The non-transitory digital storage medium according to claim 1 ,

wherein the geometric representation indicates the position and/or the orientation of the projection plane with respect to the view position.

3 . The non-transitory digital storage medium according to claim 1 ,

wherein the geometric representation indicates the position and/or the orientation of the projection plane with respect to a perspective viewing direction.

4 . The non-transitory digital storage medium according to claim 1 ,

wherein the geometric representation indicates the position and/or the orientation of the projection plane with respect to absolute coordinates of the 3D space, and

wherein the view position is represented by absolute coordinates of the 3D space.

5 . The non-transitory digital storage medium according to claim 1 ,

wherein the geometric representation is indicative of a distance between the view position and the projection plane.

6 . An apparatus for processing a bitstream, configured to retrieve, from the bitstream,

a representation of a picture, which represents a projection of a volumetric representation of an object onto a projection plane, which is positioned in a 3D space, from the perspective of a view position in the 3D space, and

a geometric representation of the projection plane in the 3D space, wherein the geometric representation is indicative of a position and an orientation of the projection plane in the 3D space, wherein the geometric representation is indicative of an orientation of the projection plane with respect to a straight line between the view position and the projection plane.

7 . The apparatus according to claim 6 ,

wherein the geometric representation is indicative of a position and/or an orientation of the projection plane in the 3D space, or

wherein the bitstream, and the geometric representation therein, is indicative of a position and/or an orientation of the projection plane in the 3D space.
