Old_version:
Here's a peek at a voxel based flight simulator engine that I have been working on.
The engine is heavily inspired by Comanche:

I've been having fun with the smooth and seamless map generation. Perhaps other folks can make use of that code.
I don't think that I am ever going to get the frame rate up to butter smooth 30fps without dropping the res so low that things are unreadable, but maybe a flight sim can settle at 15 and be okay.
Updates:
--Added controllable ship with shadow
--Up and down controls height
--Z controls thrust
--Rings to collect
--F to explore the ship / return to flight mode
-Electric Gryphon
