Stapled single card folder, with CAD designed textile swatch within. Measures 3-3/4" wide by 6-1/4" high. From IBM's Durango Pavillion at the 1968 HemisFair in San Antonio, Texas. When preparation was underway for the 1968 San Antonio HemisFair, IBM chose the Textile Graphics system for its Durango pavilion. Visitors were able to draw the design on the screen and receive a swatch of woven fabric within three minutes. The complete system is described in an IFIPS paper. The visibility of both the process and the product made a clear statement of CAD/CAM. In his book, Computer History from Pascal to von Neumann, Herman Goldstine comments on the significance of this application.In 1959 IBM began working with General Motors on an early industrial computer-aided design (CAD) system, the DAC-1. The system used a light pen to draw on the screen of a visual display unit. The project was kept secret until the 1964 Fall Joint Computer Conference. In the same year IBM released the System/360 computer with the 2250 Graphical Display Unit. Lourie had begun weaving at age seven and was an experienced weaver. In 1964 she proposed that IBM produce a CAD system for the textile industry.Lourie made a proposal to IBM management, which was accepted, to develop a working system to translate artists’ designs into loom control information, and to develop the hardware and software to control the loom. Her first article, "The textile designer of the future," explained how working with a computer would give increased freedom to textile designers. "On-line textile designing" reviewed past attempts at automating the designing process and set forth reasons why the advent of interactive tools now made aspects of this goal feasible.Lourie spent a year in three diverse textile manufacturing facilities, working alongside artists and designers, to learn the aesthetic judgments and technical skills needed to transform artwork to point paper – the preliminary representation of production control. When her software design was complete IBM filed a software patent in 1966. It was granted in 1970. It was IBM's first software patent. Related patents and later a book, Textile Graphics/Computer Aided.The Textile Graphics project then undertook the natural extensions to printed and knitted fabrics, and woven fabrics produced on a dobby loom. The algebraic formulation of the designs produced on a dobby loom is described in an ACM paper. Textile Graphics, known as GRITS (graphic interactive textile system) internally, was a precursor of today's tools that allow a personal computer user to "paint" closed areas of a design with color or patterns. The 1969 paper, "Computation of connected regions in interactive graphics", addresses the problem of automatically identifying and labeling the connected regions formed by sets of closed curves – a general problem encountered in interactive computer graphics. The first patent subsumes this capability. The subsequent patent related to connected regions, enlarged the scope of the procedure to arbitrarily large designs.
