A method and apparatus are provided for generating vector displacement maps, often in an interactive manner. Given a set of objects to be animated or imaged, they can be each represented by one or more faces. In a subdivision process, faces might be represented by polygons through a method of repeated subdividing. In the subdivision process, relative location of polygons relative to the original face (and possibly relative orientations) are maintained, for later use by other processes. This can be done by maintaining source data for each face of a subdivided surface, where source data indicates an original location on the original object that corresponds to that face and the polygons resulting from the subdividing. The source data can be a link, path, index or label for each face of the subdivision surface, where the source data indicates an original location on the original object that corresponds to that face.

Generating vector displacement maps using parameterized sculpted meshes

Digital production assets and their attributes are stored directly in a scene description database, without any association with a specific enclosing asset data file. Software applications perform database queries to retrieve assets and attributes from the database. Changes to assets or new assets are stored in the database. Query results may be cached to improve performance. Heterogeneous opinion sets including sparse opinions of attribute values may be used to specify scene description data. The database stores heterogeneous opinion set data in association with attribute values. Database-aware applications may change the scene description data in the database without loading, parsing, and instantiating scene description data. An application generates database queries and instantiates scene description data from query results for access and manipulation by other applications.
