rotate
#
- biotite.structure.rotate(atoms, angles)[source]#
Rotate the given atoms or coordinates about the x, y and z axes by given angles.
The rotations are centered at the origin and are performed sequentially in the order x, y, z.
- Parameters:
- atomsAtom or AtomArray or AtomArrayStack or ndarray, shape=(3,) or shape=(n,3) or shape=(m,n,3)
The atoms of which the coordinates are transformed. The coordinates can be directly provided as
ndarray
.- angles: array-like, length=3
The rotation angles in radians around x, y and z.
- Returns:
- transformedAtom or AtomArray or AtomArrayStack or ndarray, shape=(3,) or shape=(n,3) or shape=(m,n,3)
A copy of the input atoms or coordinates, rotated by the given angles.

Examples
Rotation about the z-axis by 90 degrees:
>>> position = np.array([2.0, 0.0, 0.0]) >>> rotated = rotate(position, angles=(0, 0, 0.5*np.pi)) >>> print(rotated) [1.225e-16 2.000e+00 0.000e+00]
