<p>A stereoscopic scene graph suitable for defining 3D- and 2D-compatible graphical objects, a storage medium comprising a scene graph for defining graphical objects, a method and an apparatus for generating such scene graphs, and a method and an apparatus for retrieving graphical objects based on such scene graphs are described. The stereoscopic scene graph is compatible to a 3D rendering mode and a 2D rendering mode and specifies a base image (BI) for a graphical object and an optional dependent image (DI) for the graphical object. For the 3D rendering mode the graphical object is composed of the base image (BI), or, if a dependent image (DI) is specified, of the base image (BI) and the dependent image (DI). For the 2D rendering mode the graphical object is composed of the base image (BI).</p> |
