Release notes: github.com/elalish/mani...

Note there are breaking changes for existing ManifoldCAD scripts, but easily updated. We now require explicit imports and exports.

Yes, self intersection is the key. I would argue that with rounded input geometry, there's no consistent way to even verify if something is self intersecting or not. Therefore manifold is instead robust to self intersection, and focuses on generating what we term epsilon-valid geometry.

All these issues are why we took a different approach with manifold. It's all basic floating point math, but structured in such a way to be manifold by construction. Once consistency is guaranteed, rounding error isn't such a problem.

Oh? What do you prefer for JS library distribution?

Thanks! Would you like to add me to this list too? Manifold is my open source library: github.com/elalish/mani...

If you like CGAL, have you tried Manifold? github.com/elalish/mani...

Excellent, it's great to hear our API is working as intended! Want to throw up a PR adding Valence to our list of users on our readme?

Dang, looks like that stack of printer paper saved him!

By the way, @bksy.bsky.social you really need to work on your image auto-cropping. In the preview of the link card, it seems to take a very narrow, vertically-centered strip of the image (pro tip: the important part of an image is toward the top). Then the real card expands it toward the bottom???

Out of curiosity, how concerned are *you* about AI taking over the world? I think the fears are mostly projection.

Thank you for your informative wit - I've been reading your column since the Dealbreaker days, and though my day job is engineering, I am also trying to write more prose.

Also interesting that their model is not at all optimized for Web delivery. This is largely independent of format, but it goes to show the state of knowledge and tooling in this area is pretty poor if even apple can't manage it. We need to make this easier...
