    This is pretty cool, and seems to be useful in order to compare various "3D model" generators that are around, would make the comparison a bit easier to make.

    Given it runs client-side, could you potentially offer like a CLI as well, or something we could integrate with other things / CI? That'd be a really nifty way of generating these diffs for later inspection.

    Wow! This looks really cool! Looking forward to playing more with this?

    Wow, just needed something like this literally yesterday, thanks OP.

    I built Meshdiff because clients keep sending me part_v3_FINAL.stl and I have no quick way to see what changed.

    Drop two STL/3MF/OBJ files → voxel diff renders in your browser. Green = added material, red = removed. Adjustable tolerance (0.05–1mm). Volume delta metrics.

    Privacy first: zero upload to any server. Everything runs client-side in a Web Worker.

    Stack: React + TypeScript, React Three Fiber, custom voxel diff engine. No Manifold/CGAL — those assume clean CSG topology; real-world STLs are triangle soup.

    If you work with 3D prints, try breaking it with your weirdest files. Real-world meshes are chaos and I need the stress test.
