Comment on What were your (now retro, but not at the time) gaming wow moments
EvilBit@lemmy.world 5 weeks agoI remember my brother telling me about Wolfenstein 3D. I insisted that something like that, that moved smoothly at your command in any direction instead of in clunky 90° turns and blockwise steps, was impossible with the current technology.
I was wrong.

you were right, the computers couldnt do the math in time. the trick was to precalculate the sin/cos tables for angle steps into tons of lookups instead.

It wasn’t just the trig tables, but realtime raycasting altogether felt like sorcery.
