I think we should remove the code not comment it. People should have learned how to make it 3d again without duplicating code.
Thats what Rene and me did for the other ones
We agreed with Rene on commenting out. If you wish, we can remove it.
Actually I also only commented out. We should think about that after the course. I will just merge ;)
mentioned in commit b16d4313
Status changed to merged
