Hello,
Some of you may already have seen my post on abime.net, but if not, I'd like to share it here as well:
I have recently picked up programming on the Amiga again, and decided to tackle the age-old problem of rendering polygons using the Amiga blitter.
I have kept a log of my progress, which you can find here (yes, it also includes some PC/DOS programming stuff, the Amiga stuff starts in part 2):

But in particular I'd like to share parts 5 and 5.1, because after dissecting the blitter's capabilities, I realized that it was possible to apply subpixel-correction to the lines, at relatively low extra cost:

Hope you guys like this little trick.
