i'm trying to run this function using vtk on a mac m1. i think the problem is with my OS and not the code itself since on another OS like windows it works
def get_thumbnail(PDF, axis):
## some code that work and create the actor
renderer = vtkRenderer()
renderer.AddActor(actor)
window = vtkRenderWindow()
window.SetOffScreenRendering(1)
window.AddRenderer(renderer)
interactor = vtkRenderWindowInteractor()
interactor.SetInteractorStyle(vtkInteractorStyleImage())
window.SetInteractor(interactor)
## HERE THE CODE GIVES THE ERROR
window.Render()
w2if = vtkWindowToImageFilter() # noqa
w2if.SetInput(window)
w2if.Update()
return w2if
getting the following error the problem suggest that i have to handle the invalidation on the Main Thread is there a way to do so that provide vtk itself
