Foreword: this is my first time doing a video tutorial. Please excuse me for any mistake, or if the explanation wasn't clear. I've also had some technical difficulties - my microphone is broken, and my webcam has a very poor quality. I recorded the tutorial (both audio and video) using my iPhone 4S. Unfortunately the quality of the markers I'm using is also poor - they're old and I couldn't find anything better, but I will buy some better markers tomorrow.

You can see an EXPERIMENTAL implementation of the merging method here:

Additional information: I've already written an article about collisions. It's outdated, but some concepts can be easier to understand in the article. I talk about spatial hashing and "overlap area" sorting, albeit in a different (and less elegant) way. If you need more info on what I'm talking about in the video, the article would be a good place to start.

When I have time, I'll update the article and put it in my website. (http://http://vittorioromeo.info/)

Please let me know if you need anything explained in the comments - and if you have suggestion on how I could record audio/video in a better way.

Thanks for watching.
