ABSTRACT:
A unified mechanism of scene description includes layering and cross-referencing relationships. The scene description specifies components using one or more layers. A layer includes an opinion of value for one or more attributes of one or more components. A layer can be sparsely populated with opinions of attribute values for only portions of components' attributes. Layers express opinions of value for an attribute using the semantic structure associated with the attribute. The scene description organizes layers in a layer hierarchy, which determines a layer stacking order. The layer stacking order specifies the compositing of opinions of attribute values to determine the complete authored state of the component. The layer stacking order enables attributes of components to be selectively overridden without disturbing other attribute values. Cross-referencing relationships enable encapsulation and reuse of components. Cross-referencing relationships can encapsulate components defined by one or more layers.
