class brainspace.vtk_interface.wrappers.renderer.BSRenderer(vtkobject=None, **kwargs)

Wrapper for vtkRenderer.

__init__(vtkobject=None, **kwargs)

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

Methods

AddActor([obj])	Set mapper.
AddActor2D([obj])	Set mapper.
AddScalarBarActor([obj])
AddTextActor([obj])
__init__([vtkobject])	Initialize self.
getVTK(*args, **kwargs)	Invoke get methods on the vtk object.
setVTK(*args, **kwargs)	Invoke set methods on the vtk object.

Attributes

vtk_map

Dictionary of vtk setter and getter methods.

AddActor(obj=None, **kwargs)

Set mapper.

Wraps the AddActor method of vtkRenderer to accept a vtkActor or BSActor.

Parameters:

• obj (vtkActor or BSActor, optional) – Actor. If None, the actor is created. Default is None.
• kwargs (optional keyword arguments) – Arguments are used to set the actor.

AddActor2D(obj=None, **kwargs)

Set mapper.

Wraps the AddActor2D method of vtkViewport to accept a vtkActor2D or BSActor2D.

Parameters:

• obj (vtkActor or BSActor) – 2D Actor.
• kwargs (optional keyword arguments) – Arguments are used to set the actor.

AddScalarBarActor(obj=None, **kwargs)

AddTextActor(obj=None, **kwargs)

getVTK(*args, **kwargs)

Invoke get methods on the vtk object.

Parameters:

• args (list of str) – Method that require no arguments.
• kwargs (list of keyword-value arguments) – key-word arguments can be use for methods that require arguments. When several arguments are required, use a tuple. Methods that require no arguments can also be used here using None as the argument.

Returns:

results (dict) – Dictionary of results where the keys are the method names and the values the results.

Examples

>>> import vtk
>>> from brainspace.vtk_interface.wrappers import BSVTKObjectWrapper
>>> m1 = BSVTKObjectWrapper(vtk.vtkPolyDataMapper())
>>> m1.getVTK('arrayId', colorModeAsString=None)
{'arrayId': -1, 'colorModeAsString': 'Default'}
>>> m1.getVTK('colorModeAsString', arrayId=None)
{'colorModeAsString': 'Default', 'arrayId': -1}
>>> m1.getVTK(numberOfInputConnections=0)
{'numberOfInputConnections': 0}

setVTK(*args, **kwargs)

Invoke set methods on the vtk object.

Parameters:

• args (list of str) – Setter methods that require no arguments.
• kwargs (list of keyword-value arguments) – key-word arguments can be use for methods that require arguments. When several arguments are required, use a tuple. Methods that require no arguments can also be used here using None as the argument.

Returns:

self (BSVTKObjectWrapper object) – Return self.

Examples

>>> import vtk
>>> from brainspace.vtk_interface.wrappers import BSVTKObjectWrapper
>>> m1 = BSVTKObjectWrapper(vtk.vtkPolyDataMapper())
>>> m1.setVTK(arrayId=3, colorMode='mapScalars')
<brainspace.vtk_interface.base.BSVTKObjectWrapper at 0x7f38a4ace320>
>>> m1.arrayId
3
>>> m1.colorModeAsString
'MapScalars'
