Modeling by Example Thomas Funkhouser,1 Michael Kazhdan,1 Philip Shilane,1 Patrick Min,2 William Kiefer,1 Ayellet Tal,3 Szymon Rusinkiewicz,1 and David Dobkin1 1Princeton University 2Utrecht University 3Technion - Israel Institute of Technology Abstract In this paper, we investigate a data-driven synthesis approach to constructing 3D geometric surface models. We provide methods with which a user can search a large database of 3D meshes to find parts of interest, cut the desired parts out of the meshes with intelligent scissoring, and composite them together in different ways to form new objects. The main benefit of this approach is that it is both easy to learn and able to produce highly detailed geometric models – the conceptual design for new models comes from the user, while the geometric details come from examples in the database. The focus of the paper is on the main research issues motivated by the proposed approach: (1) interactive segmentation of 3D surfaces, Less
