Orthogonal Slices

Download Python source code | Download Jupyter notebook

View three orthogonal slices from a mesh.

Use the pyvista.DataObjectFilters.slice_orthogonal() filter to create these slices simultaneously.

import pyvista as pv
from pyvista import examples

mesh = examples.download_embryo()
mesh.bounds

BoundsTuple(x_min =   0.0,
            x_max = 255.0,
            y_min =   0.0,
            y_max = 255.0,
            z_min =   0.0,
            z_max = 255.0)

Create three slices. Easily control their locations with the x, y, and z arguments.

slices = mesh.slice_orthogonal(x=100, z=75)

cpos = pv.CameraPosition(
    position=(540.9, -617.2, 180.5),
    focal_point=(128.3, 126.5, 111.8),
    viewup=(-0.1065, 0.03275, 0.9938),
)
dargs = dict(cmap='gist_ncar_r')

pl = pv.Plotter()
pl.add_mesh(slices, **dargs)
pl.show_grid()
pl.show(cpos=cpos)
