Not to mention crucial middleware like Umbra visibility, the development of Nvidia's RTX, an AI revolution or two, ...

As I've commented before on HN, honestly I could write a small book about these Finnish demoscene gods.

If you do please advertise it on HN. I'll buy a copy.

> development of Nvidia's RTX

like convincing Nvidia that dedicating silicon to RT calc was worth it, or writing part of the acceleration structures they use now ?

Some key publications, already quite old:

Nice so they did both hardware and software works, incredible.

The original modern tile-based rasterisation architecture is from Bitboys (also Finnish ex-demoscene), via fabled vapourware Glaze3D, which eventually made its way to AMD and Nvidia.

you should!
