Uses pen now! Much faster on the loading ends of things, and runs with 4000 stars, which gives better chances of finding type O and B stars. Use arrow keys to move around. Hover over a star with the cursor and press space to see its designation. Z and X zoom in and out. It gets a bit laggy when zoomed out and some of the pen rendering doesn't work so well when zoomed really far in, but it's a start.
(this has been sitting in my unshared folder for awhile now... not sure why I never shared it, other than the fact that it's not much different from the other starmap generator. This is just a test for something that's going to show up in ORM, a space exploration game that's #2 on my to-do list right now (after Isle of Dolor, of course). Currently it runs relatively smoothly with 4000 stars. I'm not sure whether I'd use this or the clone-based version in the final game. Of course, many things could change before I have anything close to a finished project.
