slice_along_axis

PolyData.slice_along_axis(n=5, axis='x', tolerance=None, generate_triangles=False, contour=False, bounds=None, center=None, progress_bar=False)

Create many slices of the input dataset along a specified axis.

Parameters

nint, optional

The number of slices to create.

axisstr or int

The axis to generate the slices along. Perpendicular to the slices. Can be string name ('x', 'y', or 'z') or axis index (0, 1, or 2).

tolerancefloat, optional

The tolerance to the edge of the dataset bounds to create the slices. The n slices are placed equidistantly with an absolute padding of tolerance inside each side of the bounds along the specified axis. Defaults to 1% of the bounds along the specified axis.

generate_trianglesbool, optional

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

contourbool, optional

If True, apply a contour filter after slicing.

boundssequence, optional

A 6-length sequence overriding the bounds of the mesh. The bounds along the specified axis define the extent where slices are taken.

centersequence, optional

A 3-length sequence specifying the position of the line along which slices are taken. Defaults to the center of the mesh.

progress_barbool, optional

Display a progress bar to indicate progress.

Returns

pyvista.PolyData

Sliced dataset.

Examples

Slice the random hills dataset in the X direction.

>>> from pyvista import examples
>>> hills = examples.load_random_hills()
>>> slices = hills.slice_along_axis(n=10)
>>> slices.plot(line_width=5)

Slice the random hills dataset in the Z direction.

>>> from pyvista import examples
>>> hills = examples.load_random_hills()
>>> slices = hills.slice_along_axis(n=10, axis='z')
>>> slices.plot(line_width=5)

See Slicing for more examples using this filter.
