Had the same wish after one second of rotating one pane.
Another thing that came to my mind quickly, whether it would be possible that for one object whose dimension was changed, for instance it was enlarged/shrinked in the x axis by x millimeter, to just highlight those x millimeter of difference. Similar for rotation and shift.
Suggestion: add more than one demo. The default demo right now is a little un-interesting, I'd love to be able to swap that out for a few other ones that show more complex objects.
Very cool work! Nice job. Road-map looks good too! I always appreciate client/local-first emphasis. I have been seeing a lot of great in-browser apps coming out via 3js,wasm,etc (THANK YOU LLMs)

- Fovea ArchVision (also not directly affiliated, but can attest that the team are great people.)
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.
- Multi group objs are ignored, I only see first group.
- When uploading same file twice, you should warn about it like meld does (meld says: File /home/foo/Downloads/D_LED_3mm.obj is being compared to itself)
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.

Anyway, cool!

And maybe as a preview option between branches ?
