+[Manifold](https://github.com/elalish/manifold) is a geometry library dedicated to creating and operating on manifold triangle meshes. A [manifold mesh](https://github.com/elalish/manifold/wiki/Manifold-Library#manifoldness) is a mesh that represents a solid object, and so is very important in manufacturing, CAD, structural analysis, etc. Manifold also supports arbitrary vertex properties and enables mapping of materials for rendering use-cases.

+This library is fast with guaranteed manifold output. As such you need manifold meshes as input, which this library can create using constructors inspired by the OpenSCAD API, as well as a level set function for evaluating signed-distance functions (SDF) that improves significantly over Marching Cubes. You can also pass in your own mesh data, but you'll get an error status if the imported mesh isn't manifold. We provide a [`Merge`](https://manifoldcad.org/docs/html/structmanifold_1_1_mesh_g_l_p.html) function to fix slightly non-manifold meshes, but in general you may need one of the automated repair tools that exist mostly for 3D printing.

+The most significant contribution here is a guaranteed-manifold [mesh Boolean](https://github.com/elalish/manifold/wiki/Manifold-Library#mesh-boolean) algorithm, which I believe is the first of its kind. If you know of another, please open a discussion - a mesh Boolean algorithm robust to edge cases has been an open problem for many years. Likewise, if the Boolean here ever fails you, please submit an issue! This Boolean forms the basis of a CAD kernel, as it allows simple shapes to be combined into more complex ones.
+
+Manifold has full support for arbitrary vertex properties, and also has IDs that make it easy to keep track of materials and what surfaces belong to what input objects or faces. See our [web example](https://manifoldcad.org/model-viewer.html) for a simple demonstration of combining objects with unique textures.
+
+Also included are a novel and powerful suite of refining functions for smooth mesh interpolation. They handle smoothing both triangles and quads, as well as keeping polygonal faces flat. You can easily create sharp or small-radius edges where desired, or even drive the curvature by normal vectors.
+
+To aid in speed, this library makes extensive use of parallelization through TBB, if enabled. Not everything is so parallelizable, for instance a [polygon triangulation](https://github.com/elalish/manifold/wiki/Manifold-Library#polygon-triangulation) algorithm is included which is serial. Even if compiled with parallel backend, the code will still fall back to the serial version of the algorithms if the problem size is small. The WASM build is serial-only for now, but still fast.
+
+Look in the [samples](https://github.com/elalish/manifold/tree/master/samples) directory for examples of how to use this library to make interesting 3D models. You may notice that some of these examples bare a certain resemblance to my OpenSCAD designs on [Thingiverse](https://www.thingiverse.com/emmett), which is no accident. Much as I love OpenSCAD, my library is dramatically faster and the code is more flexible.

 ### 3D Formats
 
 Please avoid saving to STL files! They are lossy and inefficient - when saving a manifold mesh to STL there is no guarantee that the re-imported mesh will still be manifold, as the topology is lost. Please consider using [3MF](https://3mf.io/) instead, as this format was designed from the beginning for manifold meshes representing solid objects.

 ## Note on memory management
 
 Since Manifold is a WASM module, it does not automatically garbage-collect like regular JavaScript. You must manually `delete()` each manifold object constructed by your scripts, see [discussion](https://github.com/elalish/manifold/discussions/256#discussioncomment-3944287).

 Please see our usage [examples](https://github.com/elalish/manifold/tree/master/bindings/wasm/examples) to see how to interface this library with `three.js`, `<model-viewer>`, and `glTF`.

This allows for the lossless and efficient transmission of manifoldness even with property boundaries.

 ## About the author
 
 This library was started by [Emmett Lalish](https://elalish.blogspot.com/). I am currently a Google employee and this is my 20% project, not an official Google project. At my day job I'm the maintainer of [\<model-viewer\>](https://modelviewer.dev/). I was the first employee at a 3D video startup, [Omnivor](https://www.omnivor.io/), and before that I worked on 3D printing at Microsoft, including [3D Builder](https://www.microsoft.com/en-us/p/3d-builder/9wzdncrfj3t6?activetab=pivot%3Aoverviewtab). Originally an aerospace engineer, I started at a small DARPA contractor doing seedling projects, one of which became [Sea Hunter](https://en.wikipedia.org/wiki/Sea_Hunter). I earned my doctorate from the University of Washington in control theory and published some [papers](https://www.researchgate.net/scientific-contributions/75011026_Emmett_Lalish).
