Abstract : We propose a method to reconstruct 3D developable surfaces from a single 2D drawing traced and annotated
over a side-view photo of a partially symmetrical object. Our reconstruction algorithm combines symmetry and
orthogonality shapes cues within a unified optimization framework that solves for the 3D position of the Bezier
control points of the drawn curves while being tolerant to drawing inaccuracy and perspective distortions. We then
rely on existing surface optimization methods to produce a developable surface that interpolates our 3D curves.
Our method is particularly well suited for the modeling and fabrication of fashion items as it converts the input
drawing into flattened developable patterns ready for sewing.
