Everyone: since @OrionReed is now developing browser extensions (https://github.com/OrionReed/dom3d), it might be best to file issues at https://github.com/OrionReed/dom3d/issues - even if they are referenced here.

I think it might make it easier to track and resolve specific things.

@ylluminate ^ absolutely. we can push improvement from that repo into this single-function gist and reference those issues/changes here.

This should be a browser plugin.

I have a updated version without the blue color:
https://gist.github.com/swnck/7aa80d2968a115ada8d920d772823cc8

@malikalimoekhamedov it is being plugin-ified here here

Beautiful

I've added some of the few major issues to the extension repo and if anyone can fix any of them I will buy you a coffee or drink of your choice!

Specifically, there are 3 issues that are causing the majority of problems:

• The z-ordering of DOM elements from the 'cameras' perspective is incorrect in some cases.
• Some websites (like GitHub) appear flat when their DOM clearly isn't.
• Some elements don't increase stack height, such as <a> and <i> tags.

Revised the gist, should now work on many more websites which previously looked flat thanks to forcing isolation: auto

This is amazing!

This is excellent. Waoh! Well done

This is great! Thanks!

Pardon my french, but what the fuck.

Very cool! Just commenting to add a link to your tweet that led me here: https://x.com/OrionReedOne/status/1772934478421188620

It's cool! Love it <3
