I am still endlessly fascinated by how modern GPUs can handle stuff like UE5, raytraced lumin (whatever) but still struggle to do 2D rendering. I mean I get it logically, but it just feels so disconnected.

Always neat to see this kind of stuff however. Very cool.

The core problem is path winding: https://en.wikipedia.org/wiki/Winding_number

Paths can be any size, and the problem is hard to parallelize. GPUs like stuff broken into small regular chunks.

TestFiles/Manchester_Union_Democrat_office_1877.svg is composed of a single huge path, which was a great torture test.
