HexEx: Robust Hexahedral Mesh Extraction

HexEx is an algorithm for extraction of hexahedral meshes from a given parametrization of a tetrahedral mesh. It is robustly detects imperfections of the parametrization and is able to meaningfully extract all hex meshes in the presence of flipped or degenerate tetrahedra.

Fast and Exact Discrete Geodesic Computation Based on Triangle-Oriented Wavefront Propagation

In this new geodesic computation framework based on triangle-oriented wavefront propagation, the triangle-oriented wavefront propagation scheme can remove most of the redundant windows at the earliest possible stage, thus significantly reducing the overall computational cost while maintaining a small memory footprint.
