quaternion#
Four-dimensional objects.
Unit quaternions are efficient objects for representing rotations, and hence orientations.
Functions
|
A vastly simplified Von Mises-Fisher distribution calculation. |
|
Return the appropriate groups for the asymmetric domain calculation. |
|
Return points symmetrically equivalent to identity with respect to |
|
Map a space group number to its (proper) point group. |
Classes
|
Quaternions. |
|
Rotations of coordinate systems, leaving objects in place. |
|
Misorientations \(M\). |
|
Orientations represent misorientations away from a reference of identity and have only one associated symmetry. |
|
Some subset of the complete space of orientations. |
|
The set of rotations comprising a point group. |
