PickingManager#

class fury.pick.PickingManager(*, vertices=True, faces=True, actors=True, world_coords=True)[source]#

Bases: object

Picking Manager helps with picking 3D objects.

__init__(*, vertices=True, faces=True, actors=True, world_coords=True)[source]#

Initialize Picking Manager.

Parameters:

  • vertices (bool) – If True allows to pick vertex indices.

  • faces (bool) – If True allows to pick face indices.

  • actors (bool) – If True allows to pick actor indices.

  • world_coords (bool) – If True allows to pick xyz position in world coordinates.

event_position(iren)[source]#

Return event display position from interactor.

Parameters:

iren (interactor) – The interactor object can be retrieved for example using providing ShowManager’s iren attribute.

pick(disp_xy, sc)[source]#

Pick on display coordinates.

Parameters:

  • disp_xy (tuple) – Display coordinates x, y.

  • sc (Scene) –

pickable_off(actors)[source]#

Choose which actors cannot be picked.

Parameters:

actors (actor or sequence of actors) –

pickable_on(actors)[source]#

Choose which actors can be picked.

Parameters:

actors (actor or sequence of actors) –

SelectionManager#
