Master’s Dissertation Defense, Sergio Nunes

We would like to congratulate Sergio Nunes da Silva Junior for his new achievement, Master in Computer Science, at the UFMG.

Title: From 2d To 3d by drawing

 

Abstract
In this work, we tackle the creation of 3D meshes from concept art. We present an automatic 3D model reconstruction method, which delivers a textured 3D triangulated mesh. Creating 3D meshes from real-life objects can be a laborious task. A wide-spread modeling approach is performed in a coarse-to-refined basis. An artist starts modeling from scratch a coarse representation of the given model and then, refines it teratively. Although this process is consolidated in the industry, it is slow and expensive. Our proposed method uses a set of only three pieces concept art of the object in different viewpoints as input. The resulting mesh is intended to replace the coarse modeling step. Also, we propose a novel constraint to improve the silhouette carving methods, which were originally not capable of modeling concave parts. We evaluate the quality of our 3D meshes by assessing its speed up with 3D artists and similar methods. Our results show a speed-up of 14% by providing the coarse model.
