rigid_body_motion.ReferenceFrame.from_translation_dataarray¶

classmethod ReferenceFrame.from_translation_dataarray(da, timestamps, parent, name=None, inverse=False, discrete=False)[source]¶

Construct a reference frame from a translation DataArray.

Parameters

da: xarray DataArray: The array that describes the translation of this frame wrt the parent frame.
timestamps: str: The name of the variable or coordinate representing the timestamps.
parent: str or ReferenceFrame: The parent reference frame. If str, the frame will be looked up in the registry under that name.
name: str, default None: The name of the reference frame.
inverse: bool, default False: If True, invert the transform wrt the parent frame, i.e. the translation is specified for the parent frame wrt this frame.
discrete: bool, default False: If True, transformations with timestamps are assumed to be events. Instead of interpolating between timestamps, transformations are fixed between their timestamp and the next one.

Returns
