Does anyone know of ways to expand this towards 3D paths with consistent screen-space stroke width?

Much simpler than the paper, but I have a 3D screen space implementation here[1].

I love this page. Thank you. I bookmarked it in 2018 but still haven't used it, doh!

https://wwwtyro.net/2019/11/18/instanced-lines.html is also nice.

Look at the quadratic bezier fragment shader in https://hhoppe.com/proj/ravg/ might generalize well zo 3d.
