Please read through the Developer Guide to get an understanding of the different trackable types: https://ar.qualcomm.at/qdevnet/developer_guide

In short, Image Targets are images (such as photos or illustrations) that are run through a pre-processing step to find a set of features. They provide robust tracking at various camera angles and distances, and you don't have to have the whole image in view to track it.

Frame Markes are preset markers with a binary pattern around the border. There are 512 of these. You can place any content you want inside the marker frame. They're easy to use, but not quite as robust as image targets.

We can't provide guidance on a per-project basis, but we can help with any specific QCAR-related questions you have. Please post those here in the forums.

It depends on what you're trying to do, and how comfortable you are with diving into unfamiliar code and working with it.

When you say markers do you mean Frame Markers? If so, I would start with the FrameMarkers sample and look at the renderFrame method in FrameMarkers.cpp. For Image Targets you would look at the renderFrame method in ImageTargets.cpp. Try to understand the code in that method, that's where you handle tracking events and do your rendering using OpenGL.
