pyCGM2.Model.frame.setFrameData#
- pyCGM2.Model.frame.setFrameData(a1: ndarray, a2: ndarray, sequence: str) Tuple[ndarray, ndarray, ndarray, ndarray] #
Sets the axes and rotation matrix of a coordinate system from two vectors and a sequence.
- Parameters:
a1 (np.ndarray) – First vector of shape (3,).
a2 (np.ndarray) – Second vector of shape (3,).
sequence (str) – Construction sequence (e.g., ‘XYZ’, ‘XYiZ’).
- Returns:
Tuple[np.ndarray, np.ndarray, np.ndarray, np.ndarray] – The x-axis, y-axis, z-axis, and rotation matrix.
