Natural lines inspired 3D shape re-design

We introduce an approach for re-designing 3D shapes inspired by natural lines such as the contours and skeletons extracted from the natural objects in images. Designing an artistically creative and visually pleasing model is not easy for novice users. In this paper, we propose to convert such a design task to a computational procedure. Given a 3D object, we first compare its editable lines with various lines extracted from the image database to explore the candidate reference lines. Then a parametric deformation method is employed to reshape the 3D object guided by the reference lines. We show that our approach enables users to quickly create nontrivial and interesting re-designed 3D objects. We also conduct a user study to validate the usability and effectiveness of our approach.
