WASD to move, arrow keys to look around, and Q and Z to change elevation. Oh, and the map at most is only 1000 x 1000 x 1000 in whatever unit the coordinates go up by so you can leave the starfield :P EDIT: Hmm... that's a strange glitch... (See if you can find it :P)
This took a while. (Especially the trigonometry.) Oh and BTW I figured out all the math but the 3D to 2D projection which I got a little help on :P
