Abstract
A trial generate the object in the natural world by computer graphics is actively done. Normally, to generate hair style is very diffficult because human's hairs are so many and so complicated. There are methods which are regarding hair as one object. But they can't generate movement. Then we draw up hair by space curve, not by texture mapping. In this paper, we propose a hair style designing system by modeling tuft partially gathering of hair, show a method of modeling tuft and a rendering method and illustrate images by using this system.
