An Amiga can’t do Wolfenstein 3D!
Like many people who grew up in the 80s and early 90s, gaming was a 2d affair for me. Scrolling, sprites and smooth animation were key elements of most action games. The Commodore 64 was an excellent gaming machine in … Continue reading

Just keeping it real, part 5.1
Picking up where I left off in part 5, the subpixel-corrected polygons on Amiga: The subpixel-correction in itself appeared to work. My analysis of the input terms for the blitter’s linedrawing appeared to be correct: you can specify the error-term … Continue reading
Just keeping it real, part 5
Ah, there it is at last, part 5! In case you were wondering why the previous two posts were not just part 5 and 6 already, well that is because they were not planned originally, and they were just things … Continue reading

Just keeping it real, part 3
Last time, I left you after an introduction to the Amiga. This time, let’s get right down to the technical stuff. The first thing we have to do, is to set up our graphics screen. More custom hardware: the copper I … Continue reading
Just keeping it real, part 2
Right, let’s just pick it back up where I left off. Last time, I spoke of the polygon fill routines that I had developed for CGA, EGA and VGA. At the time they weren’t much more than that, so there … Continue reading
Just keeping it real… old skool style
The past few days I’ve been programming some graphics… but not in the usual way… No, I had to get some things out of my system. I’ve had a lot of computers over the years, and I’ve always been interested … Continue reading
