Riassunto analitico
We propose a technique for the decomposition of 3D shapes into pieces that can be manufactured by commonly available CNC milling machines and assembled by hand. <br>The main novelty introduced by our technique is that the pieces are structured as height fields. This specific characteristic allows the use of 4 axis milling machines leading to a cheaper, faster and scalable manufacturing process. <br>The method gets as input a triangular mesh and a very coarse manifold polygonal mesh that constitute a shape abstraction of the input shape. We sample uniformly the interior of each face of the polygonal mesh to construct a distance field. <br>We designed an interlocking system that allows different pieces to plug each other to form the final shape. This interlocking mechanism is designed to offer a sufficient degree of grip such that the structure remains compact and stable once the pieces has been assembled.<br>We demonstrated the effectiveness of our approach with some printed examples.
