It doesn't seem improbable considering it's a huge performance win and perhaps many won't notice?

- mkbosmans 2y agoIt is the performance win for similar looking results that I find improbable. For a box blur to look like gaussian blur, you would need multiple passes. Even though each pass is now O(1) instead of O(n) (with n the blur radius), due to caching effects I think a gaussian kernel would still be faster, especially for the small blur radius as described in the article.
- tyleo 2y agoThe multi-pass box blur effect is the one I've seen in game engines.
