pyvista.OrthogonalPlanesSource

class OrthogonalPlanesSource(*args, **kwargs)

Orthogonal planes source.

This source generates three orthogonal planes. The output is a MultiBlock with named plane meshes 'yz', 'zx', 'xy'. The meshes are ordered such that the first, second, and third plane is perpendicular to the x, y, and z-axis, respectively.

Added in version 0.45.

Parameters:

boundsVectorLike[float], default: (-1.0, 1.0, -1.0, 1.0, -1.0, 1.0)

Specify the bounds of the planes in the form: (x_min, x_max, y_min, y_max, z_min, z_max). The generated planes are centered in these bounds.

resolutionint | VectorLike[int], default: 2

Number of points on the planes in the x-y-z directions. Use a single number for a uniform resolution, or three values to set independent resolutions.

normal_sign‘+’ | ‘-’ | sequence[‘+’ | ‘-‘], default: ‘+’

Sign of the plane’s normal vectors. Use a single value to set all normals to the same sign, or three values to set them independently.

namessequence[str], default: (‘xy’,’yz’,’zx’)

Name of each plane in the generated MultiBlock.

Examples

Generate default orthogonal planes.

>>> import pyvista as pv
>>> from pyvista import examples
>>> planes_source = pv.OrthogonalPlanesSource()
>>> output = planes_source.output
>>> output.plot()

Static Scene

Interactive Scene

Modify the planes to fit a mesh’s bounds.

>>> human = examples.download_human()
>>> planes_source.bounds = human.bounds
>>> planes_source.update()

Plot the mesh and the planes.

>>> pl = pv.Plotter()
>>> _ = pl.add_mesh(human, scalars='Color', rgb=True)
>>> _ = pl.add_mesh(output, opacity=0.3, show_edges=True)
>>> pl.show()

Static Scene

Interactive Scene

The planes are centered geometrically, but the frontal plane is positioned a bit too far forward. Use push() to move the frontal plane.

>>> planes_source.push(0.0, -10.0, 0)
>>> planes_source.update()

>>> pl = pv.Plotter()
>>> _ = pl.add_mesh(human, scalars='Color', rgb=True)
>>> _ = pl.add_mesh(output, opacity=0.3, show_edges=True, line_width=10)
>>> pl.view_yz()
>>> pl.show()
