I'm experimenting with JOGL and are currently working on a simple FPS game. However, it seems a waste of time if I'm going to figure out the best way to implement navigation in my games and apps. Are there any good tutorials on different navigation algorithms available? The different scenarios I come to think of are:

- First-Person-Shooter navigation on a flat plane (no/very simple gravitation)
- First-Person-Shooter naviagation in a terrain (with gravitation)
- Spacecraft navigation (no graviation)
- Aircraft navigation (with gravitation)

I got the math figured out, but I'd like to see some best-practice examples of how to implement it (prefferebly using JOGL, but any language will do).

Thanks!
