Synthesizing rope patterns of Jomon ware in a virtual space

彬彬

1. Introduction

Jomon ware is one of world's the earliest pottery created in

Japan from about 14,000 BC to 300 BC. Typical Jomon pot

is decorated with hand-engraved rope patterns as shown in

Figure 1(a)(b) [Habu 2004]. The rope patterns are

synthesized by rolling a rope on the surface of a pot before

baking it. Different styles of ropes make great different

rolling patterns, and each Jomon pot has characteristics that

can be traced to their age and area of origin. Many

archaeologists are doing research on the relationship

between rope styles and the patterns [Takaki et al. 2011].

In this paper, we propose a method to synthesize rope

patterns for Jomon ware in a virtual space. The user models

typical 3D rope shapes used in creating Jomon ware, and

uses these ropes on a virtual pot to make patterns

interactively. This application could help archaeologists

research the rope patterns of Jomon ware.

2. Jomon ware rope styles

The ropes for making patterns on Jomon ware are usually

made of straw. Figure 2 shows a typical style of a rope for

Jomon ware. First, a few cords are braided into a single rope.

Then, a number of single ropes are braided into a larger

compound rope. The braid direction of larger ropes is

usually opposite to the braid direction of single ropes. The

thickness of cords, the number of cords in a single rope, the

number of single ropes in a larger rope, and the braid

direction and the pitch of each rope influence the

characteristics of each compound rope.
