summary |
A major drawback of the set-theoretic solid model is the global and non-unique way in which it is defined. In a recent paper, Rossignac and Voelcker introduced the concept of the active zone of a primitive or sub-model, which provides a localization of a set-theoretic model which is useful for a number of purposes. A more general, but simplified, definition of the active zone is presented which exploits the properties of the symmetric difference operator. A novel application of the active zone to the interactive graphical editing of set- theoretic solid models is also outlined |
