This is how graphics used to be done kids

Back in the day when I was learning, there wasn’t much (or any) hardware acceleration for graphics. Programming graphics back then, on 8088/286/386 processors was much like this. Bisqwit gives it a shot.

In this tool-assisted education video I create a simple FPS style walking and jumping scene for OpenGL, with DJGPP, in DOS. In a 256 colors 320×200 VGA mode. This is my first OpenGL exercise. Apologies about some little mistakes in the program (such as reloading the textures on every frame). I noticed them when this video was already late in production, and it would take several days before the new version would be available if I were to fix them, and I’m itching to get this video out and into making the next video already, and none of the mistakes actually prevent the content being understood, so I’ll leave them be. Most people don’t even notice.

Here it is: https://bisqwit.iki.fi/jutut/kuvat/pr… Source code and prebuilt lightmaps: (Compiles and runs on Linux): https://bisqwit.iki.fi/jutut/kuvat/pr… (includes also a superior ellipsoid-based collision testing, and a buggy WIP for portal rendering: I’m not good with the math.)
