Hello Unity forums! I have been working with Unity3d for a while, but haven't had too much experience with AR and I am attempting to build a small project to try it out. There seem to be a ton of tool-kits / libraries out there but I am unsure where to look first so any help will be greatly appreciated. Also, as a student I more or less am looking to use something free. Basis of what I am looking to do, which is pretty simplistic: User can import a 3D model and anytime it is detected in the camera, the 3d model is shown on top of the real-world detected version. Thanks in advance for your help/suggestions!
