A high-level graphics programming language supporting the inquiry of graphical objects

University of British Columbia

High-level graphical programming languages provide simply expressed constructs for the definition, manipulation, and external representation of graphical data. Such languages can be used to create effective and readable application programs. This thesis investigates the value of allowing the inquiry of graphical data in a graphical language. Major design goals of an implementation of a language with these capabilities are presented. A data base model and implementation are discussed. The classification of graphical primitives as abstract data types is presented. Examples are given of several areas in which a language including graphical inquiry may be applied. It is concluded that inquiry permits the definition and manipulation of arbitrary models of graphical objects, so enabling the implementation of sophisticated graphical algorithms.
