A Search For A Computer Graphics System For The Small-Scale Computer User, Larry D. Holley
A Search For A Computer Graphics System For The Small-Scale Computer User, Larry D. Holley
Retrospective Theses and Dissertations
This paper presents a review of several computer graphics systems. The need for a universal graphics language is discussed and some typical languages are investigated. Several types of display terminals have been researched and their advantages and disadvantages have been listed. A vector plotting routine has been programmed on a microprocessor system as a part of the research. A description of the vector plotting system is included in this paper. The system could be a "modular unit" for general purpose use with any alphanumeric raster-scan display terminal and a simple graphics language.

Computer Generated Holograms, Jeffrey James Gierloff
Retrospective Theses and Dissertations
Computer generated holograms have been made practical by the introduction of fast Fourier transform algorithms. The following discussion will brief the reader on the theory and concepts of optical holograms, the computer hologram, and the analogies of the computer hologram to its optical counterpart. Some of the programming aspects of the computer holograms are presented. The results of the generation of several computer holograms are presented, and conclusions drawn as to the effectiveness of this technique. Finally, some of the practical uses and advantages of the computer hologram are discussed.
