3D Planes

3-D plane rendering places flat cross-section slices inside a PyVista 3-D scene. This is useful for showing the focal spot in the context of surrounding anatomy or experimental geometry. See the Custom sparse array and STL + Simulation examples for working code.

Unlike 3D Volume isosurfaces, plane views preserve the exact field values at each slice position without interpolation artefacts from isosurface meshing.
