matflow.param_classes.orientations.OrientationRepresentation#

class matflow.param_classes.orientations.OrientationRepresentation(type, euler_definition=None, euler_is_degrees=None, quat_order=None)#

Bases: ParameterValue

A representation descriptor of an orientation.

Parameters:

type (matflow.param_classes.orientations.OrientationRepresentationType) – How the orientation is represented.
euler_definition (matflow.param_classes.orientations.EulerDefinition | None) – For Euler angles, how the angles are applied.
euler_is_degrees (bool | None) – For Euler angles, whether the angles are in degrees or radians.
quat_order (matflow.param_classes.orientations.QuatOrder | None) – For quaternions, what is the order of the scalar wrt the vector.

Methods

`dump_element_group_to_HDF5_group`	Write a list (from an element group) of parameter values to an HDF5 group.
`dump_to_HDF5_group`	Write this parameter value to an HDF5 group.
`euler`	Make a representation of an orientation that uses Euler angles.
`prepare_JSON_dump`	Prepare this parameter value for serialisation as JSON.
`quaternion`	Make a representation of an orientation that uses quaternions.
`save_from_HDF5_group`	Extract a parameter value from an HDF5 group.
`save_from_JSON`	Extract a parameter value from JSON data.
`to_dict`	Serialise this parameter value as a dictionary.

Attributes
