I'm exploring the possibility of a #rustlang rewrite of (parts of) #vpype. It happens here:

It started as a learning experiment, but is now serious enough that I call it "vpype2".

I have many goals for vpype2—I'll write a roadmap article sometime soonish.

Lately, I worked on a GPU-accelerated viewer based on #wgpu and #egui, and it's coming along nicely. Here is some smooth zooming into some transparent lines (6k paths, 2.5M segments).

@MadMike77 Thanks, appreciated!

Yes, GPUs are fast if you “talk” to them directly. I tried multiple libs, including egui’s own painter API. All I got is a “buffer too big” error for that particular file :) Turns out rendering scale-aware “thick lines” is a rather niche topic. It took quite some time to figure out factor that with wgpu. I should write an article about this too…
