  • Saifeng Ni obtained her Ph.D. during the Fall of 2018 while working under the supervision of Dr. Xiaohu Guo in the Computer Graphics and Animation Lab. In her dissertation titled, “Variational Volumetric Meshing,” Dr. Ni discussed variational-based methods to help tackle mesh generation problems, i.e., within an energy-optimization framework. An energy that inhibits small heights is proposed to suppress almost all badly-shaped elements through tetrahedral meshing. By iteratively optimizing vertex positions and mesh connectivity, slivers are harshly suppressed even in anisotropic tetrahedral meshing. In addition, a particle-based field alignment framework is introduced. Notably, a Gaussian Hole Kernel is constructed and associated with each particle to constrain the formation of the desired one-ring structure aligned with the frame field. The minimization of the sum of Gaussian hole kernels induces an inter-particle potential energy whose minimization encourages particles to have the desired layout. A cubic one-ring structure leads to high-quality, hexahedral-dominant meshing. The one-ring structures of the BCC and FCC lattice lead to high-quality, field-aligned tetrahedral meshing. This is the first time both Riemannian distance alignment and direction alignment problem have been considered in tetrahedral meshing. In addition, field-aligned, tetrahedral meshing better preserves the rotation geometry and also creates better anisotropic meshes.  Dr. Ni has had her research published in various conference and journal publications including the Eurographics Symposium on Geometry Processing (SGP’18), International Conference on Geometric Modeling and Processing 2017 (GMP’17), 7th International ICST Conference, (WICON’13), IEEE Vehicular Technology Conference (VTC’11), and more.
