Odyssey / Alcatraz real time vectors ?

LeCaravage · 27 April 2022, 22:13

I just finished watching this demo.
I wondering if vectors are real time calculated ? Because it's probably the fastest vectors I've seen in Amiga 500 demo.

It doesn't strike me as particularly fast, the framerate drops significantly as soon as objects are not tiny on screen anymore. Sure the objects are not convex, but still.

I don't know what was precomputed (if anything) but I hope they precomputed all the math, rotations and polygon sorting / culling during the long text printer before each 3D sequence.
