Ahh. The days. I remember before I had learned about linear algebra, I saw somebody rendering molecules as 3D wire frames. I had an Amiga back then with it's "Blitter" (could draw lines in hardware, a long as you tell it which if eight octants the line's angle falls into). Then, being the geek I was, I sat down every day until I had figured out perspective transformation and rotation (later I found I had just done matrix multiplication). Of course I never thought of homogeneous coordinates, so translation was an extra step to be done for each point. Even worked out "real" red-green 3D. Oh the days when I had time for this stuff. Fond memories.
