Finished a lot of the extrusion editor and I really got itching to making part of the "game". Here's a screen shot of the game, still a huge amount left to do, but at least I have a ship that I can move around now. Also the serialization system is all done and is very nice, it really takes advantage of c# generics and reflection so that I have to do very little work. I also wrote an entire 3d transient line rendering library for draw 3d things to the screeen like 3d huds and debug info. I discovered a problem with the extrusion system where it isn't propogating the matrices in the correct order. I'll be taking a look into that next. Then I'll probable build some real art assets.
