Started up work on the AI rewrite. I've got a first cut going of path following. A path is just a series of points in 3d, and right now ships can follow that path. Eventually paths will be generated for enemies to do loops and other dogfighting maneuvers. Anyway, below is a shot of a ship successfully following the path (lines drawn in white). The little sphere is the predicted ship position in the future. The green line shows the target position the ship is aiming for.
