I have tried a lot of tutorials on the website on how to programming the slicer extension using c++. I could built a very simple extension and load it successfully. However, what I found difficult is how to get the information and send the result from and to the slicer. Different information might have different names, nodes or data structures, how could I get this information? There seems no documents on it. Such as get the images of one CT scanned images, get the models of the 3D reconstructed models by programming and so on. Which data format is the slicer using? I thought there should be some manuals or tutorials on it.
Thank you very much
