Representing three-dimensional data

摘要

A machine-readable definition of a scene including three dimensional objects is represented. A schematic representation of the scene displays an object in which elements of the object are defined by nodes and relationships between these nodes are represented by links. Several unique relationship types are used to define specific functions applying to a node or between nodes. Selection data is received in response to user input that selects one of the relationship types. Appearance of the displayed links is modified so as to identify occurrences of the selected type to the user. Furthermore, a link may be added to display a relationship type defining a specific function for two or more nodes.
