My erosion filter is out!

My erosion filter is out! Video, blog post, and shader source.
It emulates erosion without simulation, so it's fast, GPU friendly, and trivial to generate in chunks.

@JeremiahFieldhaven Glad you like it! I'm looking forward to see what people do with it

https://blog.runevision.com/2026/03/fast-and-gorgeous-erosion-filter.html@runevision Thank you, this made my day! 🤩 I didn't realise that the basic idea was so simple, with at best half-baked explanations of "gavoronoise" out there. You explained it clearly and succinctly.
In part 3 of the video, it seems like you're still using the absolute height value to decide whether something is a minimum or a maximum. Could the *second* derivative be used for that instead? I think it might work for stacked fading too.
