Figure 1:We present a data-driven framework to reform (i.e., reshape) an input multi-component mesh to simplify fabrication from a target built material. The input model (left) can be geometrically and topologically modified to a reformed shape (middle). Part conjoining specifications such as joint information can also be inferred for real fabrication (right).

Abstract

As humans, we regularly associate shape of an object with its built material. In the context of geometric modeling, however, this inter-relation between form and material is rarely explored. In this work, we propose a novel data- driven reforming (i.e., reshaping) algorithm that adapts an input multi-component model for a target fabrication material. The algorithm adapts both the part geometry and the inter-part topology of the input shape to better align with material-aware fabrication requirements. As output, we produce the reshaped model along with respective part dimensions and inter-part junction specifications. We evaluate our algorithm on a range of man-made models and demonstrate a variety of model reshaping examples focusing only on metal and wooden materials.
