Abstract
There are two main types of hula: classical hula ``kahiko'' and modern hula ``auana.'' Music, costumes, and accessories are essential to hula. Auana, in particular, is a dance set to music played with Western instruments and can express various aspects of mythology, history, and Hawaiian culture. The costumes and accessories worn by the dancers are designed to match the music. We thought that if we could freely design costumes and accessories on a computer and simulate the finished product, we would be able to create a design that was more in line with the dancer's image. This research focused on ornaments and developed a new CAD system as a result of basic research to develop a CAD system for designing "lei", one of these ornaments.
