When I was a child, I played the game Elite on my C64 for countless hours. As a teenager I wanted to create something similar on my Amiga.
This is the project I used to learn the basics of 3d graphics and rotation/projection.
It uses fixed point math and a neat look up table for the sinus/cosinus calculations and runs at 50FPS even on a stock A500/A2000.
And here it is all the wireframe glory of 1989! Of course I updated this later on and added hidden surface removal and filled and shaded polygons which will follow in a differend repository.
A prebuild binary is added in the release section.
