A semantic feature language for sculptured object modelling

Abstract

Feature technology is a promising approach for modelling an object since it provides a systematic representation scheme for the object semantics in various engineering application domains. A semantic oriented feature language is proposed in this paper to cover the modelling of the sculptured object class. The language consists of two components: vocabularies and grammar. Features and feature relationships are vocabularies of the language manipulated by the grammar. Although geometry is the main characteristic that differentiates the sculptured object from the regular shaped object, it is just a set of auxiliary information in the feature vocabulary class. The relationships between various features within a sculptured object reflecting its functionality are the major concerns. Parametric modelling of sculptured objects is also discussed in the feature language.
