Well I guess I have to figure out three more tasks:

1. Get slicer to understand the size and the shape of the viewport
2. Figure out how to call zoom function for red,green and yellow viewports. I found how to do it for the 3d Camera ([Zoom in or out via python interactor version 4.8.0 on MAC](https://discourse.slicer.org/t/zoom-in-or-out-via-python-interactor-version-4-8-0-on-mac/2254)). Considering the movement of Camera and zoom in/out in 3D world is signitifcantly different, I suppose different view/zoom in and out methods are used for red,green and yellow viewport.
3. Zoom in/out to get bounds of segment fit the viewport

To get this done correctly, I will have to spend some time

I will be reading more today and tomorrow and in the next week about this, try to figure it out…
