[vtkusers] reset camera

[Rodrigo Valiña Gutiérrez]

Hi André.

I tryed before and after reseting the camera, and it does not work, it
only moves the object a bit.

This way:

renderer.GetActiveCamera().SetViewUp(0.0, 1.0, 0.0)
renderer.ResetCamera()
#renderer.GetActiveCamera().SetViewUp(0.0, 1.0, 0.0)

It seems that ResetCameta() only resets FocalPoint, and changes the
position but not reset it.

I do the following. It matters?

self.widget.GetInteractorStyle().SetCurrentStyleToTrackballCamera()

Any idea?

Rodrigo
