__init__()

Methods

__init__()
addMotionFrame(frame)	Append a Frame instance to the motion attribute.
getAxisTrajectory(axis)	Return the trajectory of a specified axis.
getNodeTrajectory(label)	Return the trajectory of a node.
getOriginTrajectory()	Return the trajectory of the origin of the referential.
setStaticFrame(frame)	Set the static pose of the referential.

addMotionFrame(frame: Frame)

Append a Frame instance to the motion attribute. :param frame: A Frame instance representing a pose at a specific time frame. :type frame: Frame

getAxisTrajectory(axis: str) → ndarray

Return the trajectory of a specified axis. :param axis: Axis for which the trajectory is required. Must be ‘X’, ‘Y’, or ‘Z’. :type axis: str

Returns:

np.ndarray – Trajectory of the specified axis.

getNodeTrajectory(label: str) → ndarray

Return the trajectory of a node. :param label: Label of the desired node. :type label: str

Returns:

np.ndarray – Trajectory of the specified node.

getOriginTrajectory() → ndarray

Return the trajectory of the origin of the referential. :Returns: np.ndarray – Trajectory of the origin.

setStaticFrame(frame: Frame)

Set the static pose of the referential. :param frame: A Frame instance to set as the static pose. :type frame: Frame
