ヒューマンフレンドリーな曲線生成法の開発

抄録

A new curve generation method is proposed which permits a designer to draw a curve on a computer as if he or she is drawing on a piece of paper. This method is intended for the early stage of design and relieves a designer from the burden of generating a curve using control points. The conventional approaches require mathematical knowledge about control points to generate the desired curve, and what is worse, it is very difficult to modify it once it is drawn. Our new method is unique in that it pays attention to the trend of the data a designer generates and fits an exact curve by extracting feature points. Thus, we can modify the curve globally or locally as desired. Furthermore, it imposes very little burden on the computer.
