“DECO: a designing editor for line stone decoration” by Igarashi

Line stone decoration is popular with young people. They enjoy applying line stone decorations to personal goods, such as notebook PCs, mobile phones and digital cameras. However, novices often find line stone decorations difficult to design, as the user must consider stroke length, stone width, and stone spacing. Hence, many people employ off-the-shelf design sheets or have their items decorated by an in-store professional. We have developed an interactive designing editor for line stone decoration. The user interactively draws freeform strokes on the canvas, as shown in Figure 1. The system then automatically generates a virtual line stone image (Fig. 1(b)), in which none of the stones overlap. Various off-line methods have been proposed for designing such decorations (e.g., tile mosaics [Hausner 2001]). Using our system, the user can create the designs interactively at the computer. Our system also creates a physical stencil pattern to help novice users to construct real line stone (Fig. 1 (c), (d)).
