Physically Based Rendering in Filament

Man, I got excited for a second from the title thinking this was about a way to produce 3d printer filament from PBR settings, so you could tweak a material on the computer and have your filament match the digital version

It is funny u say that because my head went directly to physically based rendering but i dont 3d print.

that's going to be a confusing name with the connections to 3D printing

I'm not sure how it's confusing. Is it any more confusing than "v8" also being a type of internal combustion engine or blender also being a kitchen appliance?
NBJack
Yes.
v8 as a drink and as an engine.
blender as a piece of software and as an appliance
filament as a physical building material and as a physical rendering material.
One of these things is not like the other (or rather, one of these things sounds very much like the other).

You can make lithophanes with 3d prints. I don't know about anyone else but that's what I thought this post would be about.

v8 is also a beverage.

I use the page to test scrolling.

Nice, it's also a great test for my https://github.com/EsportToys/LibreScroll
Filament is a great lightweight cross-platform PBR rendering library. There's a few things missing (real GPU instancing is one), but in terms of shadows/antialiasing/color grading, it's very powerful. The material (shader) language is also very accessible.
I maintain an open-source Dart/Flutter package[0] which is mostly a wrapper around Filament. This makes it considerably easier to have a single UI+codebase that runs across macOS, iOS, Android, Windows, and Web.
