twitvault VS contrast_renderer

Another shameless plug: I made a cross platform "native (Rust with Webkit)" desktop app that does the same thing (Win/Lin/Mac). It also allows you to see your "profile" afterwards in the app, search within your Tweets, and allows backing up things like mentions, responses, likes, etc:

I recently build this side project with Dioxus:

Here's a review of the experience of using it:

This is true, but there is a lot more to the story. For one, WebGPU does not (yet) support mesh shaders, though it may later as an extension. For two, consider a glyph such as "o" that has two contours. Real triangulation generates a mesh that only generates triangles between the outer and inner contours, and mesh shaders aren't good at that. There are techniques (cover and stencil) that draw twice, incrementing and decrementing a winding number stored in the stencil buffer (see contrast renderer[1] for a clean modern implementation), but it does require nontrivial tracking on the CPU side, and can result in lots of draw calls to switch between the cover and stencil stages unless sophisticated batching is done.

Compute shaders avoid all these problems and work on WebGPU 1.0 today.

Thanks!

You can also checkout the "feature/ui" branch in GIT [1] to get the UI framework prototype.
