That suddenly brought back a memory of the first 3d rendering code I did - it was written in Basic on an 8086 machine running DOS 2.1. Not only did it take several seconds to render, it was only an unshaded wireframe line drawing. To be fair, there were techniques available at the time to make it quite a bit faster that I didn’t know. But it still blows my mind a little bit every time I think about how far things have come since I was a kid.
