RotationSequence3D

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

Bases: astropy.modeling.Model

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

Positive angles represent a counter-clockwise rotation.

Parameters

anglesarray_like

Angles of rotation in deg in the order of axes_order.

axes_orderstr

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')

Methods Summary

__call__(self, *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(self, x, y, z, angles)	Apply the rotation to a set of 3D Cartesian coordinates.
