The purpose of this study was to write a computer program that would not only output a color pattern weave to a cathode ray tube (CRT), but would also analyze a painted design and output a printed diagram that would show how to set up a loom in order to produce the woven design. The first of seven chapters describes the problem and the intent of the study, while the second clarifies the basic process of drafting through a description of conventional drafting methods. Computer aided drafting of a textile design is briefly explained in the third chapter, which also describes the development of a program that defines a traditional pattern draft as a matrix and outputs it to a color monitor and a line printer. It is noted that this program is closely modeled after the methods used to generate a pattern weave draft by hand, and that it will not only produce a diagram, but translate it into a texture form for mapping onto a two or three dimensional surface. Some of the problems encountered in programing the texture mapping for this study, which is currently limited to two dimensional surfaces, are discussed in the fourth chapter, and advantages and disadvantages of designing textile pattern weaves by computer program are considered in the fifth. A discussion of educational and industrial applications of computer-aided textile design is presented in the sixth chapter, and the final chapter briefly considers future possibilities for the use of computers as visual design tools for both education and industry. The text is illustrated by 24 figures and a glossary is provided, as well a 22-item bibliography and 13 references. (Author/MES)
