Visualization of lattice orientations

Rodrigues vectors are a convenient way to visualize (distributions of) lattice orientations. See the paper “Representation of orientation and disorientation data for cubic, hexagonal, tetragonal and orthorhombic crystals” by A. Heinz and P. Neumann for more details.
