How to use doubles to get more precesion? Could you write about this more detail?
How translating the whole world to fixed distance could cause bugs? Dos it not the same as moving the whole world?
BTW, I susprect, that game logic gets more complicated if I need to move the whole world with many objects instead of one camera. What if I want to move not only camera. but also binded object? I need to move everything except 1 model and camera? Did I undertand you correctly?
