pyvista.AxesGeometrySource.symmetric_bounds#
- property AxesGeometrySource.symmetric_bounds: bool[source]#
Enable or disable symmetry in the axes bounds.
This option is similar to
symmetric
, except instead of making the axes parts symmetric, only the bounds of the axes are made to be symmetric. This is achieved by adding a single invisible cell to each tip dataset along each axis to simulate the symmetry. Setting this parameter primarily affects camera positioning and is useful if the axes are used as a widget, as it allows for the axes to rotate about its origin.Examples
Get the symmetric bounds of the axes.
>>> import pyvista as pv >>> axes_geometry_source = pv.AxesGeometrySource( ... symmetric_bounds=True ... ) >>> axes_geometry_source.output.bounds BoundsTuple(x_min=-1.0, x_max=1.0, y_min=-1.0, y_max=1.0, z_min=-1.0, z_max=1.0)
>>> axes_geometry_source.output.center (0.0, 0.0, 0.0)
Get the asymmetric bounds.
>>> axes_geometry_source.symmetric_bounds = False >>> axes_geometry_source.output.bounds BoundsTuple(x_min=-0.10000000149011612, x_max=1.0, y_min=-0.10000000149011612, y_max=1.0, z_min=-0.10000000149011612, z_max=1.0)
>>> axes_geometry_source.output.center (0.45, 0.45, 0.45)
Show the difference in camera positioning with and without symmetric bounds. Orientation is added for visualization.
Create actors.
>>> axes_sym = pv.AxesAssembly( ... orientation=(90, 0, 0), symmetric_bounds=True ... ) >>> axes_asym = pv.AxesAssembly( ... orientation=(90, 0, 0), symmetric_bounds=False ... )
Show multi-window plot.
>>> pl = pv.Plotter(shape=(1, 2)) >>> pl.subplot(0, 0) >>> _ = pl.add_text("Symmetric bounds") >>> _ = pl.add_actor(axes_sym) >>> pl.subplot(0, 1) >>> _ = pl.add_text("Asymmetric bounds") >>> _ = pl.add_actor(axes_asym) >>> pl.show()
