Hi , First I want to thank you all for your wonderful app and incredible support ,
I a new to 3Dslicer and I wrote a python code for generating cross-sectional images . I am trying to build a module in 3Dslicer that gives 360 projection images as an input and after using the code renders the final 3D volume.
where should I start to do so ?

Maybe this will help:
> **[RTK - Reconstruction Toolkit](https://www.openrtk.org/)**

> RTK is an open-source, cross-platform system that provides developers with an extensive suite of software tools for image analysis.
