    We present a new approach to reconstruction of high-relief models from hand-made drawings. Our method is tailored to an interactive modeling scenario where the input drawing can be separated into a set of semantically meaningful parts of which relative depth order is known beforehand. For this kind of input, our technique allows inflating individual components to have a semi-elliptical profile, position them to satisfy prescribed depth order, and provide their seamless interconnection. As compared to previous similar frameworks our approach is the first that formulates this reconstruction process as a joint non-linear optimization problem. Although its direct optimization is computationally demanding we propose an approximative solution which delivers comparable results orders of magnitude faster enabling an interactive response. We evaluate our approach on various hand-made drawings and demonstrate that it provides stateof-the-art quality in comparison with previous methods which require comparable user intervention.
