get_sample_reduced_fundamental#
- orix.sampling.get_sample_reduced_fundamental(resolution: float = 2, method: str | None = None, point_group: Symmetry | None = None) Rotation [source]#
Return a grid of rotations that rotate the Z-vector (0, 0, 1) into the fundamental sector of a point group’s Laue group.
The rotations are constrained in that the first Euler angle is \(\phi_1 = 0^{\circ}\).
- Parameters:
- resolution
The characteristic distance between a rotation and its neighbour in degrees. Default is 2 degrees.
- method
Name of method to mesh the unit sphere. See
orix.sampling.sample_S2()
for options. If not given, a suitable default is chosen given by the crystal system of the given point group.- point_group
Point group with symmetry operations that define the
fundamental_sector
on the unit sphere. If not given, rotations that rotate the Z-vector onto the whole sphere are returned.
- Returns:
R
Rotations of shape
(n, 3)
.
