We propose an automatic PolyCube-Maps construction scheme. Firstly, input mesh is decomposed into a set of feature regions, and further split into patches. Then, each region is approximated by a simple basic polycube primitive with each patch mapped to a rectangular sub-surface of the basic polycube primitive which can be parameterized independently. After that, an iterative procedure is performed to improve the parameterization quality globally. By these steps, we can obtain the polycubic parameterization result efficiently.

In this paper, we develop a novel mesh fusion method controlled by sketches, which allows users to construct complex 3D polygon models fast and easily. The user first cuts needed parts from some existing objects and puts them in right pose. Then, a radial basis function (RBF) based implicit surface is adopted to smoothly fuse the parts. To achieve better shape control for the transition part in fusion, our method let users using sketches to specify the expected silhouette. After that, the implicit surface is sampled by particles and meshed into a polygonal surface joining the separated parts into one single model. Compared with other previous methods, our mesh fusion approach overcomes the topological limitations and can merge multiple parts together at once. [ABSTRACT FROM AUTHOR]
