A Systematic Method for the Creation of Data Structures in Computer Graphics Applications.

Abstract : The dissertation describes a systematic method for creating data structures for applications in computer graphics. With this method the user is able to think and work abstractly, on paper, with minimal regard to computer memory structure because a distinction is made between the user's data structure and the computer's memory structure. First, the user defines his own familiar graphical symbols for his application and then he proceeds to define images in terms of these symbols. A graphical notation is presented which allows the designer to construct his models on paper in a way that is similar to drawing flowcharts for computer programs. A systematic approach is maintained throughout, from the initial formulation of the abstract model, to the final creation of the data structure in the computer. Numerous examples are given. A chapter on the representation and processing of relations is also included. (Author)
