Notes Notes
----- -----
Polar coordinates follow the conventions typically used in physics, The default crystal direction (θ=0,φ=0) direction is [0 0 1],
see https://en.wikipedia.org/wiki/Spherical_coordinate_system. the default sample direction (θ=0,φ=0) is z.
The common ranges are 0≤θ≤π and 0≤φ≤2π for a unique set of coordinates. Polar coordinates follow the ISO 80000-2:2019 convention
typically used in physics.
See https://en.wikipedia.org/wiki/Spherical_coordinate_system.
Ranges 0≤θ≤π and 0≤φ≤2π give a unique set of coordinates.
