Hello !

I want to develop an extension that will have a custom view. The view consist of three 3D views side by side. In one view I want to have a source model, in the second view I want to have the target model and in the third view both source and target with the result.  
Is there documentation that could help me achieve this ?

Thank you very much.

You can achieve this using [custom layouts.](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#customize-view-layout). Feel free to post back if you run into problems implementing.
