Picking points on a mesh#
This example demonstrates how to pick points on meshes using
import pyvista as pv
Pick points on a sphere#
sphere = pv.Sphere() p = pv.Plotter() p.add_mesh(sphere, pickable=True) p.enable_point_picking() p.show()
Ignore the 3D window#
In the above example, both points on the mesh and points in the 3d window can be selected. It is possible instead pick only points on the mesh.
sphere = pv.Sphere() p = pv.Plotter() p.add_mesh(sphere, pickable=True) p.enable_point_picking(pickable_window=False) # Make the 3D window unpickable p.show()
Modify which actors are pickable#
After enabling point picking, we can modify which actors are pickable.
sphere = pv.Sphere() cube = pv.Cube() cube.translate([10, 10, 0]) p = pv.Plotter() sphere_actor = p.add_mesh(sphere, pickable=True) # initially pickable cube_actor = p.add_mesh(cube, pickable=False) # initially unpickable p.enable_point_picking(pickable_window=False) p.pickable_actors = [sphere_actor, cube_actor] # now both are pickable p.view_xy() p.show()
