Japanese folding paper is one of Japanese historical culture. Recently, it´s used for rehabilitation or applied for structure analysis of industrial packing. However, Japanese folding paper may be recognized as a plaything for children in Japan. Otherwise it is recognized as a good educational material for low aged children in the world.

To spread the Japanese folding paper to the world by improving the teaching method, we developed the navigation system of Japanese folding paper named PCML (Paper Craft making Language) and PCML browser. PCML shows the Japanese folding paper as the 3DCG animation with collision detection algorithm we developed. In this paper, we describe the detail of PCML and PCML browser.
