Abstract
A scene graph suitable for defining stereoscopic graphical objects, a method and an apparatus for creating such scene graphs, and a method and an apparatus for rendering graphical objects based on such scene graphs are described. The scene graph describes a spatial or a temporal arrangement of the stereoscopic graphical object and comprises information about image data for a base image for the stereoscopic graphical object, image data for a dependent image for the graphical object, and the spatial or the temporal arrangement of the base image and the dependent image. For a 3D rendering mode the graphical object is composed of the base image and the dependent image. For a 2D rendering mode the graphical object is composed of the base image only.
