[Neuroimaging] [Dipy] VTK animation of tractography

[Eleftherios Garyfallidis]

Hi Paolo,

The new user interface allows that. You could have buttons that can hide
objects or manipulate other objects.
Also you can have a timer callback which can allow you to animate.

How urgently you need this feature? We can either give you some older
branches that show you how to animate
or you can wait until all the UI components are in place. It all depends if
you want a quick solution or a long term
solution.

Best regards,
Eleftherios
