Implementation of structured display files in interactive colour graphics

This paper discusses the various types of data structure used in computers, analyses their advantages and disadvantages, and assesses their suitability for use in microprocessor-based interactive computer graphics. Its main purpose is to define a display file structure which introduces levels of hierarchy amongst the elements of computer-generated images. The use of structured display files arises from the need to assist the user of an interactive system by supplying the software tools required to allow easy manipulation of the image contents.
