Abstract

A method and apparatus is provided for forming a model of a structure. Input data comprising a set of values for a set of attributes is received. The set of values for the set of attributes is matched to a number of texture decks in a plurality of texture decks. A texture deck in the plurality of texture decks is associated with a set of assigned attributes. Each assigned attribute in the set of assigned attributes is assigned at least one assigned value. A texture deck from the number of texture decks is selected as a final texture deck for use in forming the model of the structure.
