Computational fabrication is an emerging research topic in computer graphics, beginning roughly a decade ago with the need to develop computational solutions for efficient 3D printing and later for 3D fabrication and object assembly at large. In this talk, I will introduce a series of research works in this
area with a particular focus on the following two recent ones:

(i) Computational LEGO Technic assembly, in which we model the component bricks, their connection mechanisms, and the input user sketch for computation, and then further develop an optimization model with necessary constraints and our layout modification operator to efficiently search for an optimum LEGO Technic assembly. Our results not only match the input sketch with coherently-connected LEGO Technic bricks but also respect the intended symmetry and structural integrity of the designs.
(ii) TilinGNN, the first neural optimization approach to solve a classical instance of the tiling problem, in which we formulate and train a neural network model to maximize the tiling coverage on target shapes, while avoiding overlaps and holes between the tiles in a self-supervised manner. In short, we model the tiling problem as a discrete problem, in which the network is trained to predict the goodness of each candidate tile placement, allowing us to iteratively select tile placements and assemble a tiling
on the target shape.
In the end, I will try to present also some of the results from my other research works in the areas of point cloud processing, 3D vision, and augmented reality.



Chi-Wing Fu is an associate professor in the department of computer science and engineering at the Chinese University of Hong Kong (CUHK). His research interests are in computer graphics, vision, and human-computer interaction, or more specifically in computation fabrication, 3D computer vision, and user interaction. Chi-Wing obtained his B.Sc. and M.Phil. from the CUHK and his Ph.D. from Indiana University, Bloomington. Before re-joining the CUHK in early 2016, he was an associate professor with tenure at the school of computer science and engineering at Nanyang Technological University, Singapore.
