Hi
I reworked some of my old terrain rendering stuff I used to play around with in the PDA days. It used to be in C on the PDA, now I just did a very quick port to java (not using fixed point arithmetic but floats in stead).
I don't get it as snappy as I want, could be optimized a lot further.
extract the AVCHD folder to some USB storage device and run it
Use the arrow keys to turn and control the speed, use the square and X to change the altitude of the player's view.
the flight2 directory has the source, see how small the actual render routine is. It is a ray caster based on this article :
