I am developing a 3D slicer module for augmented reality application for the video based navigation system. I had already built slicer 4.8.1 from the source file using Cmake and visual studio 2013 version. I had built slicer.exe file. But after that how to build a module and add up the camera (NDI Polaris)? I don’t know how to do that. Is there any tutorial so that I can do that by myself?

Here an an intro tutorial for programming python modules: [https://www.slicer.org/wiki/Documentation/Nightly/Training#Slicer4\_Programming\_Tutorial](https://www.slicer.org/wiki/Documentation/Nightly/Training#Slicer4_Programming_Tutorial)

This page has an overview of the different types of modules, with guides for getting started for the different types:

For connecting to the NDI Polaris, the best approach would be the SlicerOpenIGTLink extension ([https://github.com/openigtlink/SlicerOpenIGTLink](https://github.com/openigtlink/SlicerOpenIGTLink), available in the extension manager) with PLUS Toolkit handling the interaction with the camera ([https://plustoolkit.github.io/](https://plustoolkit.github.io/), [http://perk-software.cs.queensu.ca/plus/doc/nightly/user/DeviceNDI.html](http://perk-software.cs.queensu.ca/plus/doc/nightly/user/DeviceNDI.html))

The SlicerIGT extension ([http://www.slicerigt.org/wp/](http://www.slicerigt.org/wp/)) may also have some good resources, depending on what you are trying to do.
