# Examples from pyvista.Transform.rotate
# ======================================

# Compose a rotation matrix. In this case the rotation rotates about the
# z-axis by 90 degrees.
import pyvista as pv
rotation_z_90 = [[0, -1, 0], [1, 0, 0], [0, 0, 1]]
transform = pv.Transform().rotate(rotation_z_90)
transform.matrix

# Compose a second rotation matrix. In this case we use the same rotation as
# before.
_ = transform.rotate(rotation_z_90)

# The result is a matrix that rotates about the z-axis by 180 degrees.
transform.matrix

# Rotate about a point. Check the `matrix_list` to see that a translation
# is added before and after the rotation.
transform = pv.Transform().rotate(rotation_z_90, point=(1, 2, 3))
translation_to_origin = transform.matrix_list[0]
translation_to_origin

rotation = transform.matrix_list[1]
rotation

translation_from_origin = transform.matrix_list[2]
translation_from_origin
