Better to change mousemove with pointermove to make it works on touchscreen. Though it will be bit annoying to scroll on mobile phone.
Another way to make it seamless on mobile phone is by handle deviceorientation event then use: alpha, beta, gamma; value 🤔

Great..! it was cool..

Anyone remember when Firefox had a far better version of this built in? https://www.youtube.com/watch?v=zqHV625EU3E

yes

@krzentner could you give an example of the isolation: isolate issue? Happy to make the change once I see what it's doing.

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!

FYI you can make a bookmarklet in Firefox/Chrome and add this as the url to create a 1-click way of loading this into any site.

This is excellent. Waoh! Well done

This is great! Thanks!

Pardon my french, but what the fuck.

edit: the video isn't embedding. basically, it causes firefox to spaz out on twitter.

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

Very cool bookmarklet! Some of y'all may find my service, bookmarkl.ink, handy to distribute things like this. Here's this bookmarklet all packed up: https://bookmarkl.ink/OrionReed/4c3778ebc2b5026d2354359ca49077ca. Cheers!

Here's a slightly simpler version, would still love to figure out the draw ordering bugs (if that's even possible without control over the DOM)

(() => {
  const COLOR_HUE = 190; // hue in HSL (https://hslpicker.com)
  const THICKNESS = 20; // thickness of layers

  const getDOMDepth = () => {
    let m = 0;
    const t = (e, d) => {m = Math.max(m, d); for(let c of e.children) t(c, d + 1)};
    t(document.body, 0);
    return m;
  };

  const maxDepth = getDOMDepth();
  const getColorByDepth = depth => `hsl(${COLOR_HUE}, 75%, ${5 + (depth * 80 / maxDepth)}%)`;

  // Rotate the document based on mouse position
  document.addEventListener("pointermove", ({clientX, clientY}) => {
    const rotationY = 180 * (0.5 - clientY / innerHeight);
    const rotationX = 180 * (clientX / innerWidth - 0.5);
    document.body.style.transform = `rotateX(${rotationY}deg) rotateY(${rotationX}deg)`;
  });

  // Apply initial styles to the body to enable 3D perspective
  Object.assign(document.body.style, {
    perspective: `${10000}px`,
    overflow: "visible",
    perspectiveOrigin: `${innerWidth/2}px ${innerHeight/2}px`,
    transformOrigin: `${innerWidth/2}px ${innerHeight/2}px`
  });

  // Recursive function to traverse child nodes and apply 3D styles
  const traverseDOM = (node, depthLevel) => {
    // Only process element nodes
    if (node.nodeType !== 1) return;
    
    // Style current node
    Object.assign(node.style, {
      transform: `translateZ(${THICKNESS}px)`,
      backfaceVisibility: "hidden", // helps with performance
      isolation: "auto",
      transformStyle: "preserve-3d",
      backgroundColor: getColorByDepth(depthLevel),
    });

    // Traverse children
    for (const childNode of node.children) {
      traverseDOM(childNode, depthLevel + 1);
    }
  }

  traverseDOM(document.body, 0);
})()

^ ths minifies into just this

(()=>{const e=(()=>{let e=0;const t=(n,i)=>{e=Math.max(e,i);for(let e of n.children)t(e,i+1)};return t(document.body,0),e})();document.addEventListener("pointermove",(({clientX:e,clientY:t})=>{const n=180*(.5-t/innerHeight),i=180*(e/innerWidth-.5);document.body.style.transform=`rotateX(${n}deg) rotateY(${i}deg)`})),Object.assign(document.body.style,{perspective:"10000px",overflow:"visible",perspectiveOrigin:`${innerWidth/2}px ${innerHeight/2}px`,transformOrigin:`${innerWidth/2}px ${innerHeight/2}px`});const t=(n,i)=>{if(1===n.nodeType){var o;Object.assign(n.style,{transform:"translateZ(20px)",backfaceVisibility:"hidden",isolation:"auto",transformStyle:"preserve-3d",backgroundColor:(o=i,`hsl(190, 75%, ${5+80*o/e}%)`)});for(const e of n.children)t(e,i+1)}};t(document.body,0)})();
