This is the end of this book and I would like to congratulate you. I know it is a lot of work to read a complete programming book and do all the examples to understand a new topic, but it is also really rewarding and the new knowledge will be yours forever. I hope you enjoyed this book and it taught you enough to be able to create your own interactive 3D applications, because, in my opinion, this is one of the most interesting and fast-moving areas of programming and computer science in general.
