Spinel Antialiasing — Summary

Below is an animation that shows the significant pixel differences between type rendered with Spinel’s default antialiasing and Chrome, Microsoft Edge and Adobe Illustrator with NV Path enabled.

Using Beyond Compare, if a pixel difference is greater than 25 then it is drawn in red.

Spinel antialiasing appears most similar to Chrome and Edge and least similar to the antialiasing produced by Adobe Illustrator with NV Path + MSAA 8x.

And for the two sRGB-aware pipelines, here are animations comparing Spinel and NV Path (MSAA 8x):

The takeaway from this series of posts is that Spinel’s default antialiasing is high quality and at least as effective as what’s produced by high quality CPU rasterizers.

So can Spinel improve its antialiasing even further? Yes. We’ll cover that in a future post.
