  Code related to meshing and interpolation of grain boundaries by representing 5DOF of grain boundaries as grain boundary octonions and mapping them into a Voronoi Fundamental Zone. ([https://github.com/sgbaird-5DOF/interp](https://github.com/sgbaird-5DOF/interp))

+<sup> Figure adapted based on table of contents from DOI: 10.1016/j.commatsci.2021.110756 (a) grain boundary energy (GBE) values plotted continuously between two arbitrary grain boundary octonions (i.e. changes in all 5DOF). (b) 2D analogy of a Grain Boundary Octonion Voronoi Fundamental Zone (GBO-VFZ). Dark blue points are mapped into the VFZ. (c) Hexagonally binned parity plot of GPR predictions colored by number of points per bin. </sup>
