weldx.transformations.WXRotation.create_group¶

classmethod WXRotation.create_group(group, axis='Z')¶

Create a 3D rotation group.

Parameters

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

Returns

rotation – Object containing the elements of the rotation group.

Return type

Rotation instance

Notes

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