Abstract

A method and an apparatus for processing a scene description for a rendering device are described, wherein the method may comprise receiving a scene description comprising a data model defining an interactive scene comprising 3D objects, the data model including hierarchically organized nodes, the nodes including object nodes, each object node being associated with a 3D object and with object metadata, the object metadata including information about interaction with the 3D object by a user or based on physics simulation; receiving a sequence of update patches for updating the scene description, wherein each application of an update patch to the scene description is associated with an updated interactive scene to be rendered by the rendering device; determining a protected scene description associated with the sequence of update patches, the protected scene description including object protection metadata for identifying one or more object nodes in the data model as protected objects nodes, the object protection metadata signalling the rendering device that interaction with 3D objects associated with protected object nodes by a user or based on physics simulation is disabled or limited when the sequence of update patches are applied to the protected scene description; and, transmitting the protected scene description and the at least one update patch to the rendering device.
