DataSet.points#
- property DataSet.points: pyvista_ndarray[source]#
Return a reference to the points as a NumPy object.
- Returns:
pyvista_ndarrayReference to the points as a NumPy object.
Examples#
Download Python source code | Download Jupyter notebook
Create a mesh and return the points of the mesh as a NumPy array.
>>> import pyvista as pv
>>> cube = pv.Cube()
>>> points = cube.points
>>> points
pyvista_ndarray([[-0.5, -0.5, -0.5],
[-0.5, -0.5, 0.5],
[-0.5, 0.5, 0.5],
[-0.5, 0.5, -0.5],
[ 0.5, -0.5, -0.5],
[ 0.5, 0.5, -0.5],
[ 0.5, 0.5, 0.5],
[ 0.5, -0.5, 0.5]], dtype=float32)
Shift these points in the z direction and show that their position is reflected in the mesh points.
>>> points[:, 2] += 1
>>> cube.points
pyvista_ndarray([[-0.5, -0.5, 0.5],
[-0.5, -0.5, 1.5],
[-0.5, 0.5, 1.5],
[-0.5, 0.5, 0.5],
[ 0.5, -0.5, 0.5],
[ 0.5, 0.5, 0.5],
[ 0.5, 0.5, 1.5],
[ 0.5, -0.5, 1.5]], dtype=float32)
You can also update the points in-place:
>>> cube.points[...] = 2 * points
>>> cube.points
pyvista_ndarray([[-1., -1., 1.],
[-1., -1., 3.],
[-1., 1., 3.],
[-1., 1., 1.],
[ 1., -1., 1.],
[ 1., 1., 1.],
[ 1., 1., 3.],
[ 1., -1., 3.]], dtype=float32)
