Practical Papercraft Models from Meshes

Abstract

我們提出了一個新的自動化產生紙模型系統。使用二次曲面區塊來近似使用者輸入的3D模型，再將每個二次曲面區塊切割、攤平為紙模型樣式。我們的系統有以下優點：第一，所產生的紙模型有較平滑的外觀；第二，紙模型樣式的邊緣平滑、規則，方便使用者剪裁與黏貼；第三，使用預先定義的剪裁規則，產生有意義的紙模型樣式。我們將做出實際的模型來說明本系統。

We present a new approach to generate papercraft models from meshes. The input mesh is approximated by a set of quadric surface proxies. Each quadric proxy is then cut and unfolded into a 2D papercraft pattern. Our method has the following advantages : First, we produce smoother papercraft models than previous methods. Second, the 2D patterns of papercraft models are easy to cut and glue. Finally, the 2D patterns of papercraft models are more meaningful due to the pre-defined cutting rules. We demonstrate this by physically assembling papercraft models from our algorithm.
