pyvista.DataSetFilters.slice

DataSetFilters.slice(

normal='x',

origin=None,

generate_triangles=False,

contour=False,

progress_bar=False,

)

Slice a dataset by a plane at the specified origin and normal vector orientation.

If no origin is specified, the center of the input dataset will be used.

Parameters:

normalsequence[float] | str, default: ‘x’

Length 3 tuple for the normal vector direction. Can also be specified as a string conventional direction such as 'x' for (1, 0, 0) or '-x' for (-1, 0, 0), etc.

originsequence[float], optional

The center (x, y, z) coordinate of the plane on which the slice occurs.

generate_trianglesbool, default: False

If this is enabled (False by default), the output will be triangles. Otherwise the output will be the intersection polygons.

contourbool, default: False

If True, apply a contour filter after slicing.

progress_barbool, default: False

Display a progress bar to indicate progress.

Returns:

pyvista.PolyData

Sliced dataset.

Examples

Slice the surface of a sphere.

>>> import pyvista as pv
>>> sphere = pv.Sphere()
>>> slice_x = sphere.slice(normal='x')
>>> slice_y = sphere.slice(normal='y')
>>> slice_z = sphere.slice(normal='z')
>>> slices = slice_x + slice_y + slice_z
>>> slices.plot(line_width=5)
