26 Enhancing and Modifying the Scene

From the Form data, one can reconstruct a scene by placing each artifact in layout according to its placement as specified in the Embedding, defined in 21-Scene. Modules can also add additional information to enhance or modify the scene by making use of the FormMetadata, FormProperties, and EmbeddingProperties types. These types by default include only empty objects, i.e., objects with no members, representing no additional or altered behavior beyond placing artifacts in the layout member.

In this section, we go through some modules that can be used to enhance or modify the scene. These modules are not part of the core specification and implementations MAY implement them.
