pyvista.DataSetFilters.rotate

DataSetFilters.rotate(

rotation: RotationLike,

point: VectorLike[float] | None = None,

transform_all_input_vectors: bool = False,

inplace: bool = False,

)

Rotate mesh about a point with a rotation matrix or Rotation object.

Note

See also the notes at transform() which is used by this filter under the hood.

Parameters:

rotationRotationLike

3x3 rotation matrix or a SciPy Rotation object.

pointVectorLike[float], optional

Point to rotate about. Defaults to origin.

transform_all_input_vectorsbool, default: False

When True, all input vectors are transformed. Otherwise, only the points, normals and active vectors are transformed.

inplacebool, default: False

Updates mesh in-place.

Returns:

pyvista.DataSet

Rotated dataset.

Concatenate a rotation matrix with a transformation.

Examples

Define a rotation. Here, a 3x3 matrix is used which rotates about the z-axis by 60 degrees.

>>> import pyvista as pv
>>> rotation = [
...     [0.5, -0.8660254, 0.0],
...     [0.8660254, 0.5, 0.0],
...     [0.0, 0.0, 1.0],
... ]

Use the rotation to rotate a cone about its tip.

>>> mesh = pv.Cone()
>>> tip = (0.5, 0.0, 0.0)
>>> rot = mesh.rotate(rotation, point=tip)

Plot the rotated mesh.

>>> pl = pv.Plotter()
>>> _ = pl.add_mesh(rot)
>>> _ = pl.add_mesh(mesh, style='wireframe', line_width=3)
>>> _ = pl.add_axes_at_origin()
>>> pl.show()
