Sequence	All the operations on a read-only sequence.

PickingManager

class fury.pick.PickingManager(vertices=True, faces=True, actors=True, world_coords=True)

Bases: object

__init__(vertices=True, faces=True, actors=True, world_coords=True)

Picking Manager helps with picking 3D objects

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)

Returns 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)

Pick on display coordinates

Parameters

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

• sc (Scene) –

pickable_off(actors)

Choose which actors cannot be picked

Parameters

actors (actor or sequence of actors) –

pickable_on(actors)

Choose which actors can be picked

Parameters

actors (actor or sequence of actors) –

SelectionManager

class fury.pick.SelectionManager(select='faces')

Bases: object

__init__(select='faces')

Selection Manager helps with picking many objects simultaneously

Parameters

select ('faces') – Options are ‘faces’, ‘vertices’ or ‘actors’. Default ‘faces’.

select()

pick()

event_position(iren)

Returns event display position from interactor

Parameters

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

pick(disp_xy, sc)

Pick on display coordinates returns a single object

Parameters

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

• sc (Scene) –

select(disp_xy, sc, area=0)

Select multiple objects using display coordinates

Parameters

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

• sc (Scene) –

• area (int or 2d tuple of ints) – Selection area around x, y coords.

selectable_off(actors)

Choose which actors cannot be selected

Parameters

actors (actor or sequence of actors) –

selectable_on(actors)

Choose which actors can be selected

Parameters

actors (actor or sequence of actors) –

update_selection_type(select)

Update selection type

Parameters

select ('faces') – Options are ‘faces’, ‘vertices’ or ‘actors’. Default ‘faces’.

Sequence

class fury.pick.Sequence

Bases: collections.abc.Reversible, collections.abc.Collection

All the operations on a read-only sequence.

Concrete subclasses must override __new__ or __init__, __getitem__, and __len__.

__init__()

Initialize self. See help(type(self)) for accurate signature.

count(value) → integer -- return number of occurrences of value

index(value[, start[, stop]]) → integer -- return first index of value.

Raises ValueError if the value is not present.

Supporting start and stop arguments is optional, but recommended.
