pyvista.ImageData.origin

property ImageData.origin: Tuple[float]

Return the origin of the grid (bottom southwest corner).

Examples

>>> import pyvista as pv
>>> grid = pv.ImageData(dimensions=(5, 5, 5))
>>> grid.origin
(0.0, 0.0, 0.0)

Show how the origin is in the bottom “southwest” corner of the ImageData.

>>> pl = pv.Plotter()
>>> _ = pl.add_mesh(grid, show_edges=True)
>>> _ = pl.add_axes_at_origin(ylabel=None)
>>> pl.camera_position = 'xz'
>>> pl.show()

Interactive Scene

Set the origin to (1, 1, 1) and show how this shifts the ImageData.

>>> grid.origin = (1, 1, 1)
>>> pl = pv.Plotter()
>>> _ = pl.add_mesh(grid, show_edges=True)
>>> _ = pl.add_axes_at_origin(ylabel=None)
>>> pl.camera_position = 'xz'
>>> pl.show()
