The objective of the present study is to investigate how to apply CG to the educational purpose in the field of textile. We take up a patchwork quilt designed and drawn by CAD. CG, because a patchwork quilt has been very popular among and familiar to a lot of people not only in the western world but in Japan.
The hardware components consist of a NEC-9801VX personal computer, a NEC PCKD853 display, a EPSON HG-2550 printer, and a GP9901 XY plotter. We use MS-DOS as operation system and N88BASIC as computer language.
The three-dimensional surface of a real patchwork quilt can be illustrated on a computer screen as two-dimensional geometric image. Multicolored lights can also be created and displayed on the screen by mixing the three primary colors (i.e. red, green, and blue) by the computer. We have created a sample of color which can display sixteen different colors simultaneously on the screen out of 4096 colors. The plotter enables us to draw an image of a patchwork quilt of various sizes on the screen, so that we can make patterns automatically.
The software we have created for the present study enables us to visualize the entire image of a patchwork quilt on a computer screen. In addition, the availability of the total 4096 colors as well as the easy access to a variety of images of a patchwork quilt on a screen will make color coordination and design work by CG easier and, of course, will serve the purpose in textile education.

Today education using computers has become an important issue. Even in the field of formative arts and design, some reform is required by increasing the use of the computer. It is a tool with continually advancing technology and the latest computer graphics, are capable of individual expresson. We therefore read a new teaching method.
In this paper we explain what we have been considering about the basic educational connection between computer graphics and formative arts and design and their creativity, giving some examples of a course which adopts computer graphics practically in the college and the professional school. This time we describe especially the study of form. We researched to learn how the study of form is taught in conventional course, for example, “proportion and arrangement”, “visual effects and the development of form”, “the making of forms and their constitution”. We then examinal methods and forms using computer graphics.
