scipy.spatial.transform.Rotation.create_group

Rotation.create_group()

Create a 3D rotation group.

Parameters
groupstring

The name of the group. Must be one of ‘I’, ‘O’, ‘T’, ‘Dn’, ‘Cn’, where n is a positive integer. The groups are:

  • I: Icosahedral group

  • O: Octahedral group

  • T: Tetrahedral group

  • D: Dicyclic group

  • C: Cyclic group

axisinteger

The cyclic rotation axis. Must be one of [‘X’, ‘Y’, ‘Z’] (or lowercase). Default is ‘Z’. Ignored for groups ‘I’, ‘O’, and ‘T’.

Returns
rotationRotation instance

Object containing the elements of the rotation group.

Notes

This method generates rotation groups only. The full 3-dimensional point groups [PointGroups] also contain reflections.
