I forgot to update my streak here, but while I've been gone I've mostly finished the project. The models have been brought into the Unity project and I've trained the program to recognise natural images instead of markers so that I can use images that look more like a picture book than markers do.

One issue I had with the Live2D models is that they're normally not intended for 3D environments, so when you make animations they don't clip the model to the background, because it's assumed that you'll place it in a normal 2D frame yourself as you please, but that's not the case when you work in AR and have a freely moving camera. I solved this by making a simple png file with a box which I set the model parts to clip to and then turned the opacity of the box to 0% so that the box clips the parts of the model I want to hide without being visible, and then keyed the parameters for the box in the animation files so that I can use the same model for all the animations and have custom heights of visibility for them all.

What's left to do is simply to make sure that everything works, put the book together neatly and do the required writing. I should have no problem getting it done by Wednesday.

Solved my SDK/JDK issues and managed to get simple AR working in a simple Android apk!
