Hi @hardikdava 👋🏻 Is it ready for review?

[hardikdava]

@SkalskiP Yeah, it is ready for review.

[SkalskiP]

@hardikdava I tried to run Notebook but it crashed. Is it up to date?

[hardikdava]

@SkalskiP Ohh, it is an issue of image downloading.

[hardikdava]

@SkalskiP Can you manually upload this image for testing? It should work. I just tested it.

Hi @hardikdava 👋🏻 I'd add some unit tests to this PR. I can do that if ou don't have time.

[SkalskiP]

Hi @hardikdava 👋🏻 I will work on a few unit tests before merging.

[hardikdava]

@SkalskiP Thanks for covering some tasks for me.

[SkalskiP]

@hardikdava can I only ask one question? Why is _offset_generation producing offsets with 4 coordinates and not just two? I would assume we could move boxes with just x and y vectors.

[hardikdava]

@SkalskiP yeah, we can do it with just x and y.

[SkalskiP]

I'll try to do some minor changes when I'll be working on tests.

[SkalskiP]

@hardikdava slicer looks fantastic!
