Fast vector rendering on GPU compute; strong WebGPU demo
From 2 comments
I'm very happy to see this work! The era of rendering vector graphics in GPU compute shaders is upon us, and I have no doubt it we'll start seeing these in production soon, as…
raphlinus on HNThis is cool. Being able to render SVG animations natively, without having to embed a browser, is awesome. The map of Paris rendered in 40ms on my M1 Air which is crazy…

Could help games and animation tools needing vector graphics
From 2 comments
A while ago I wanted to make some vector-based toy games for fun. I surveyed the available options and basically couldn't find any. If an engine supports vector graphics, it…
Waterluvian on HNabout a decade ago I wanted to get started prototyping gameplay with vector graphics and I was dismayed at the state of available libraries to do this efficiently. I'm glad…

Missing stroke support limits comparisons and use

I just tried it in my own renderer (that uses tiny-skia) to compare performance, but unfortunately forma is still lacking some features to do a proper comparison (strokes, the…

The README mentions WebGPU - do you have a URL to a demo of this running in the browser using WebAssembly?

More implementation detail in documentation

Please, write more about the implementation! There is so little information on this topic in general. Like, how does sorting pixel segments result in coverage masks? Is there an…

How it compares to Skia and tiny-skia
From 2 comments
I'm curious how this relates to Skia (the library that handles cross-platform rendering for Chrome and Flutter). Seems like this could be an alternative backend but also could…

What a pixel segment and its sort order are
From 2 comments
> Line segments are transformed into pixel segments by intersecting them with the pixel grid. We developed a simple method that performs this computation in O(1) and which is run…
tayistay on HNOk, and when you sort these pixel-contained segments, what's the ordering?

Haven't Skia et al been GPU accelerated for ages?
gct on HNYes, Skia uses the traditional method of tessellating path geometry on the CPU and then having the GPU handle transforming and shading it as if it were 3D geometry. Compare that…
