Development and Evaluation of Multi Modification Design Model: Visual Expression by a Computer without CG Technology

This paper details a "Multi Modification Design Model", a new type of design that authors have developed. In recent years, expressive abilities by CG have been enhanced. In other words, complicated images and drawings that require much calculation became possible and easy due to the speeding up of computer processing. However this alone cannot broaden the variety of expressivity of visual expression by a computer we need to extend its ability. The "Multi Modification Design Model" proposed by the authors, does not take so-called CG, technology and explores a, new visual expression by a computer, with a totally different approach.
