RotationSequence3D

class astropy.modeling.rotations.RotationSequence3D(angles, axes_order, name=None)

Bases: Model

Perform a series of rotations about different axis in 3D space.

Positive angles represent a counter-clockwise rotation.

Parameters:

anglesnumpy:array_like

Angles of rotation in deg in the order of axes_order.

axes_orderpython:str

A sequence of ‘x’, ‘y’, ‘z’ corresponding to axis of rotation.

Examples

>>> model = RotationSequence3D([1.1, 2.1, 3.1, 4.1], axes_order='xyzx')

Attributes Summary

angles
n_inputs	The number of inputs.
n_outputs	The number of outputs.
param_names	Names of the parameters that describe models of this type.
standard_broadcasting

Methods Summary

__call__(*inputs[, model_set_axis, ...])	Evaluate this model using the given input(s) and the parameter values that were specified when the model was instantiated.
evaluate(x, y, z, angles)	Apply the rotation to a set of 3D Cartesian coordinates.

Attributes Documentation

angles = Parameter('angles', value=[])

n_inputs = 3

The number of inputs.

n_outputs = 3

The number of outputs.

param_names = ('angles',)

Names of the parameters that describe models of this type.

The parameters in this tuple are in the same order they should be passed in when initializing a model of a specific type. Some types of models, such as polynomial models, have a different number of parameters depending on some other property of the model, such as the degree.

When defining a custom model class the value of this attribute is automatically set by the Parameter attributes defined in the class body.

standard_broadcasting = False

Methods Documentation

__call__(*inputs, model_set_axis=None, with_bounding_box=False, fill_value=nan, equivalencies=None, inputs_map=None, **new_inputs)

Evaluate this model using the given input(s) and the parameter values that were specified when the model was instantiated.

evaluate(x, y, z, angles)

Apply the rotation to a set of 3D Cartesian coordinates.
