example of ipywidgets interaction

[vianamp]

Hey Marco.

I am trying to come up with a simple example where I use ipywidget to control an actor, but I had no success so far. Would you have any suggestion?

This is what my code looks like right now:

from vtkplotter import *
from ipywidgets import interact

vp = Plotter()
s = Sphere()
vp.add(s)
def f(x):
    s.pos(x,x,x)
interact(f, x=10)
vp.show()

Hi Matheus
loops and widgets from inside notebooks with the k3d backend are not yet functional.
It's on my to-do list, but i'll only able to implement it later next week.. for the moment the only option is to pop up a normal vtk rendering window, something like this:
(with additional limitation that one cannot interact smoothly with the rendered scene)

from vtkplotter import *
from ipywidgets import interact, Button

embedWindow(False)

vp = Plotter(axes=True, interactive=False)

vp += Cube()
s = Sphere()
vp += s

def f(x):
    s.pos(x,x,x)
    vp.show(resetcam=False)

def b(b):
    vp.close()

interact(f, x=10)
button = Button(description="close window")
button.on_click(b)   
display(button)

Thank you Marco. This worked fine for now.
vtkPlotter is already very nice, but the full integration with widgets will put vtkPlotter in another level definitely.
