1. A method for rendering a 3D scene on a terminal, the method comprising:
receiving, at the terminal, a manifest, wherein the manifest includes:
a reference to at least one first data stream available from a server, the at least one first data stream comprising a central patch content of the 3D scene, the central patch content comprising parts of the scene visible from a central viewpoint;
a reference to a plurality of second data streams available from the server, the plurality of second data streams comprising parallax patch content of the 3D scene, wherein the parallax patch content comprises parts of the 3D scene visible from a secondary non-central viewpoint; and
an association of each of the second data streams to a range of depths;
requesting, from the server, at least one available first data stream;
requesting, from the server, a subset of available second data streams selected based at least on a range of depths associated with the at least one available second data stream; and
rendering the 3D scene using the central patch content from the requested first data streams and parallax patch content from the requested selected subset of available second data streams.
