-[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. Our primary goal is reliability: guaranteed manifold output without caveats or edge cases. Our secondary goal is performance: efficient algorithms that make extensive use of parallelization, or pipelining when only a single thread is available.

 ## Users
 
-Here is an incomplete list of our users, whose integrations may be anywhere from in-progress to released. Please feel free to send a PR to update this list with your own project - it's quite difficult for us to keep track.
+[OpenSCAD](https://openscad.org/), [IFCjs](https://ifcjs.github.io/info/), [Grid.Space](https://grid.space/), and [OCADml](https://github.com/OCADml/OManifold) have all integrated our Manifold geometry kernel! Why? Because its reliability is guaranteed and it's 1,000 times faster than other libraries. See our [usage](https://github.com/elalish/manifold/discussions/340) and [performance](https://github.com/elalish/manifold/discussions/383) discussions for all the latest and to add your own projects & analyses.

-If you like OpenSCAD / JSCAD, you might also like [ManifoldCAD][ManifoldCAD.org] - our own solid modelling web app where you script in JS/TS. This uses our npm package, [manifold-3d](https://www.npmjs.com/package/manifold-3d), built via WASM. It's not quite as fast as our raw C++, but it's hard to beat for interoperability.

-If you prefer Python to JS/TS, make your own copy of [the notebook][Python Colab Example]. It demonstrates interop between our [`manifold3d`](https://pypi.org/project/manifold3d/) PyPI library and the popular [`trimesh`](https://pypi.org/project/trimesh/) library, including showing the interactive model right in the notebook and saving 3D model output.

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. Further information can be found on the [wiki](https://github.com/elalish/manifold/wiki/Manifold-Library).
 
-![A metallic Menger sponge](https://manifoldcad.org/samples/models/mengerSponge192.png "A metallic Menger sponge")
+This is a modern C++ library that Github's CI verifies builds and runs on a variety of platforms. Additionally, we build bindings for JavaScript ([manifold-3d](https://www.npmjs.com/package/manifold-3d) on npm), Python, and C to make this library more portable and easy to use.
 
-## Manifold Library
+System Dependencies (note that we will automatically download the dependency if there is no such package on the system):
+- [`GLM`](https://github.com/g-truc/glm/): A compact header-only vector library.
+- [`Thrust`](https://github.com/NVIDIA/thrust): NVIDIA's parallel algorithms library (basically a superset of C++17 std::parallel_algorithms)
+- [`tbb`](https://github.com/oneapi-src/oneTBB/): Intel's thread building blocks library. (only when `MANIFOLD_PAR=TBB` is enabled)
+- [`gtest`](https://github.com/google/googletest/): Google test library (only when test is enabled, i.e. `MANIFOLD_TEST=ON`)
 
-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.
+Other dependencies:
+- [`Clipper2`](https://github.com/AngusJohnson/Clipper2): provides our 2D subsystem
+- [`quickhull`](https://github.com/akuukka/quickhull): 3D convex hull algorithm.
+
+## What's here

As such you need manifold meshes as input, which this library can create using constructors inspired by the OpenSCAD API, as well as more advanced features like smoothing and signed-distance function (SDF) level sets. You can also pass in your own mesh data, but you'll get an error status if the imported mesh isn't manifold. Various automated repair tools exist online for fixing non manifold models, usually 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.
+To aid in speed, this library makes extensive use of parallelization, generally through Nvidia's Thrust library. You can switch between the TBB, and serial C++ backends by setting a CMake flag. 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.
 
-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.

 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.
 
-### Dependencies
-
-Manifold no longer has **any** required dependencies! However, we do have several optional dependencies, of which the first two are strongly encouraged:
-| Name | CMake Flag | Provides |
-| --- | --- | --- |
-| [`TBB`](https://github.com/oneapi-src/oneTBB/) |`MANIFOLD_PAR=ON` | Parallel acceleration |
-| [`Clipper2`](https://github.com/AngusJohnson/Clipper2) | `MANIFOLD_CROSS_SECTION=ON` | 2D: [`CrossSection`](https://manifoldcad.org/docs/html/classmanifold_1_1_cross_section.html) |
-| [`Nanobind`](https://github.com/wjakob/nanobind) | `MANIFOLD_PYBIND=ON` | Python bindings |
-| [`Emscripten`](https://github.com/emscripten-core/emscripten) | `MANIFOLD_JSBIND=ON` | JS bindings via WASM |
-| [`GTest`](https://github.com/google/googletest/) | `MANIFOLD_TEST=ON` | Testing framework |
-| [`Assimp`](https://github.com/assimp/assimp) | `ASSIMP_ENABLE=ON` | Utilities in `extras` |
-| [`Tracy`](https://github.com/wolfpld/tracy) | `TRACY_ENABLE=ON` | Performance analysis |
-

-### 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. 
-
-If you use vertex properties for things like interpolated normals or texture UV coordinates, [glTF](https://www.khronos.org/Gltf) is recommended, specifically using the [`EXT_mesh_manifold`](https://github.com/KhronosGroup/glTF/blob/main/extensions/2.0/Vendor/EXT_mesh_manifold/README.md) extension. This allows for the lossless and efficient transmission of manifoldness even with property boundaries. Try our [make-manifold](https://manifoldcad.org/make-manifold) page to add this extension to your existing glTF/GLB models. 
-
-Manifold provides high precision OBJ file IO, but it is limited in functionality and is primarily to aid in testing. If you are using our npm module, we have a much more capable [gltf-io.ts](https://github.com/elalish/manifold/blob/master/bindings/wasm/examples/gltf-io.ts) you can use instead. For other languages we strongly recommend using existing packages that focus on 3D file I/O, e.g. [trimesh](https://trimesh.org/) for Python, particularly when using vertex properties or materials.
-Example for integrating with [Assimp](https://github.com/assimp/assimp) is in `extras/meshIO.cpp`, which is used by files such as `extras/convert_file.cpp`.

 ## Building
 
 Only CMake, a C++ compiler, and Python are required to be installed and set up to build this library (it has been tested with GCC, LLVM, MSVC). However, a variety of optional dependencies can bring in more functionality, see below.

 ## Contributing
 
 Contributions are welcome! A lower barrier contribution is to simply make a PR that adds a test, especially if it repros an issue you've found. Simply name it prepended with DISABLED_, so that it passes the CI. That will be a very strong signal to me to fix your issue. However, if you know how to fix it yourself, then including the fix in your PR would be much appreciated!
 
-### Formatting
-
-There is a formatting script `format.sh` that automatically formats everything.
-It requires clang-format, black formatter for python and [gersemi](https://github.com/BlankSpruce/gersemi) for formatting cmake files.
-
-Note that our script can run with clang-format older than 18, but the GitHub
-action check may fail due to slight differences between different versions of
-clang-format. In that case, either update your clang-format version or apply the
-patch from the GitHub action log.
-
-### Profiling
+## Profiling
 
 There is now basic support for the [Tracy profiler](https://github.com/wolfpld/tracy) for our tests.
 To enable tracing, compile with `-DTRACY_ENABLE=on` cmake option, and run the test with Tracy server running.
-To enable memory profiling in addition to tracing, compile with `-DTRACY_MEMORY_USAGE=ON` in addition to `-DTRACY_ENABLE=ON`.
-
-### Fuzzing
-
-To build with fuzzing support, you should set the following with CMake:
-
-- Enable fuzzing by setting `-DMANIFOLD_FUZZ=ON`
-- Disable python bindings by setting `-DMANIFOLD_PYBIND=OFF`
-- Use `clang` for compiling by setting `-DCMAKE_CXX_COMPILER=clang++`
-- You may need to disable parallelization by setting `-DMANIFOLD_PAR=OFF`, and set `ASAN_OPTIONS=detect_container_overflow=0` when building the binary on MacOS.

-# Python Bindings
-
-## Autogenerated Doc-Strings
-
-Doc-strings for the python API wrapper are generated by gen_docs.py
-The script is run automatically during the build to keep python
-doc strings fully up-to-date with c++ sources.
-
-It scrapes documentation comments and c++ function signatures
-from the manifold c++ sources, in order to generate a c++ header file 
-exposing the comments as string variables named by function names.
-This allows python bindings to re-use the c++ comments directly.
-
-Some snake-casing of params is applied for python use case.
-
----
-
-When modifying the Manifold C++ sources, you may need to update
-gen_docs.py. For example, top-level free functions are white-listed,
-so if you add a new one, you will need to add it in gen_docs.py.
-
-Similarly, the list of source files to parse is also white listed,
-so if you define functions in new files that need python wrappers,
-you will also need to up gen_docs.py.
-
-To verify that python docs are correct after changes, you can
-run the following commends from the manifold repo root:
-```
-pip install .
-python -c 'import manifold3d; help(manifold3d)'
-```
-
-Alternatively you could generate stubs with nanobind python module
-```
-pip install -m nanobind
-python -m nanobind.stubgen -m manifold3d -o manifold3d.pyi -i=. -p=bindings/python/stub_pattern.txt
-```
-It will emit some warnings and write a file `manifold3d.pyi`
-which will show all the function signatures and docstrings.

-cross_section__warp__warp_func:
-  Move the vertices of this CrossSection (creating a new one) according to
-  any arbitrary input function, followed by a union operation (with a
-  Positive fill rule) that ensures any introduced intersections are not
-  included in the result.
-  :param warp_func: A function that takes the original vertex position and
-  return the new position.
-cross_section__warp_batch__warp_func:
-  Same as CrossSection::warp but calls warpFunc with
-  an ndarray[n, 2] instead of processing only one vertex at a time.
-  :param warp_func: A function that takes multiple vertex positions as an
-  ndarray[n, 2] and returns the new vertex positions.
-manifold__warp__warp_func:
-  This function does not change the topology, but allows the vertices to be
-  moved according to any arbitrary input function. It is easy to create a
-  function that warps a geometrically valid object into one which overlaps, but
-  that is not checked here, so it is up to the user to choose their function
-  with discretion.
-  :param warp_func: A function that takes the original vertex position and
-  return the new position.
-manifold__warp_batch__warp_func:
-  Same as Manifold::warp but calls warpFunc with with
-  an ndarray[n, 3] instead of processing only one vertex at a time.
-  :param warp_func: A function that takes multiple vertex positions as an
-  ndarray[n, 3] and returns the new vertex positions. The result should have the
-  same shape as the input.
-manifold__smooth__mesh_gl__sharpened_edges:
-  Constructs a smooth version of the input mesh by creating tangents; this
-  method will throw if you have supplied tangents with your mesh already. The
-  actual triangle resolution is unchanged; use the Refine() method to
-  interpolate to a higher-resolution curve.
-  By default, every edge is calculated for maximum smoothness (very much
-  approximately), attempting to minimize the maximum mean Curvature magnitude.
-  No higher-order derivatives are considered, as the interpolation is
-  independent per triangle, only sharing constraints on their boundaries.
-  :param mesh: input Mesh.
-  :param sharpened_edges: If desired, you can supply a vector of sharpened
-  halfedges, which should in general be a small subset of all halfedges. Order
-  of entries doesn't matter, as each one specifies the desired smoothness
-  (between zero and one, with one the default for all unspecified halfedges)
-  and the halfedge index (3 * triangle index + [0,1,2] where 0 is the edge
-  between triVert 0 and 1, etc).
-  :param edge_smoothness: Smoothness values associated to each halfedge defined
-  in sharpened_edges. At a smoothness value of zero, a sharp crease is made. The
-  smoothness is interpolated along each edge, so the specified value should be
-  thought of as an average. Where exactly two sharpened edges meet at a vertex,
-  their tangents are rotated to be colinear so that the sharpened edge can be
-  continuous. Vertices with only one sharpened edge are completely smooth,
-  allowing sharpened edges to smoothly vanish at termination. A single vertex
-  can be sharpened by sharping all edges that are incident on it, allowing cones
-  to be formed.

-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' implies that there are no gaps or tears, and that all faces are oriented outwards.

-[Manifold](https://github.com/elalish/manifold) is a geometry library dedicated to creating and operating on manifold triangle meshes.  It is available as a WASM module that runs in any modern browser.
-
-Our primary goal is reliability: guaranteed manifold output without caveats or edge cases. Our secondary goal is performance: efficient algorithms that make extensive use of parallelization, or pipelining when only a single thread is available.

-If you like OpenSCAD / JSCAD, you might also like ManifoldCAD - our own solid modelling web app where you script in JS/TS and save a GLB or 3MF file. It contains several examples showing how to use our API to make interesting shapes. 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, this library is dramatically faster and the code is more flexible.

-manifoldCAD = manifold + [TypeScript](https://www.typescriptlang.org/) + [glTF](https://www.khronos.org/gltf/)
+[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. Further information can be found on the [wiki](https://github.com/elalish/manifold/wiki/Manifold-Library).
 
-<div style="clear:both"></div>
+## What's here
 
-<!-- #endregion IncludeInUserGuide -->
-<!-- #region NoStlPlease -->
+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 more advanced features like smoothing and signed-distance function (SDF) level sets. You can also pass in your own mesh data, but you'll get an error status if the imported mesh isn't manifold. Various automated repair tools exist online for fixing non manifold models, usually for 3D printing. 
 
-## 3D Formats
+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.
 
-[ [EXT_mesh_manifold](https://manifoldcad.org/docs/jsapi/modules/manifold-gltf.html) ]
+## Note on memory management
 
-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. 
+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).
 
-If you use vertex properties for things like interpolated normals or texture UV coordinates, [glTF](https://www.khronos.org/Gltf) is recommended, specifically using the [`EXT_mesh_manifold`](https://github.com/KhronosGroup/glTF/blob/main/extensions/2.0/Vendor/EXT_mesh_manifold/README.md) extension. This allows for the lossless and efficient transmission of manifoldness even with property boundaries. Try our [make-manifold](https://manifoldcad.org/make-manifold) page to add this extension to your existing glTF/GLB models. 
+## Examples
 
-<!-- #endregion NoStlPlease -->
+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`. Of particular note are the included libraries for lossless roundtrip of manifold meshes through glTF files, via a new extension: [EXT_manifold](https://github.com/KhronosGroup/glTF/pull/2286). 
 
 ## About the author
 
-This library was started by [Emmett Lalish](https://elalish.blogspot.com/), currently a senior rendering engineer at Wētā FX. This was my 20% project when I was a Google employee, though my day job was maintaining [\<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).

-# Using Manifold
-
-## Installation
-
-In your project root folder run:
-
-```bash
-npm install --save manifold-3d
-```
-
-To start using Manifold, import it and initialize it:
-
-```js
-import Module from 'manifold-3d';
-
-const wasm = await Module();
-wasm.setup();
-const { Manifold } = wasm;
-```
-
-Intro example
-
-```js
-const {cube, sphere} = Manifold;
-const box = cube([100, 100, 100], true);
-const ball = sphere(60, 100);
-const result = box.subtract(ball);
-```
-
-## Memory Management
-
-> [!WARNING]
-> Since Manifold is a WASM module, it does not automatically garbage-collect like regular JavaScript.
-
-You must manually `delete()` each object constructed by your scripts (both `Manifold` and `CrossSection`).
-See [discussion](https://github.com/elalish/manifold/discussions/256#discussioncomment-3944287).
-
-## Examples

-## Debugging
-
-To debug the WASM build directly in Chrome dev tools, simply build in debug mode:
-```
-emcmake cmake -DCMAKE_BUILD_TYPE=Debug .. && emmake make
-```
-and install the [DWARF](goo.gle/wasm-debugging-extension) Chrome extension.
-
-When testing [ManifoldCAD.org](https://manifoldcad.org/) (either locally or the
-deployed version) note that it uses a service worker for faster loading. This
-means you need to open the page twice to see updates (the first time loads the
-old version and caches the new one, the second time loads the new version from
-cache). To see changes on each reload, open Chrome dev tools, go to the
-Application tab and check "update on reload".
-
-## Documentation
-
-This guide and the ManifoldCAD User Guide are built using [TypeDoc](https://typedoc.org).
-
-### Building Documentation
-
-Documentation can be built using NPM:
-
-```bash
-cd bindings/wasm
-npm install
-npm run build
-npm run docs
-```
-
-After this, the User and Developer docs will be in `docs/jsuser` and `docs/jsapi` respectively.
-
-### Writing for the User Guide
-
-The ManifoldCAD User Guide is generated from the declaration files present in `types/`.  These mostly re-export declarations, allowing the User Guide to inherit from the Developer Guide.  
-
-TypeDoc reflections (comments) flagged as `@internal` will _not_ be visible in the User Guide, but will be present in the Developer Guide.  Reflections tagged as `@hidden` will not be visible in either guide.
-
-### WASM Bindings
-
-The manifold library itself is documented in three files:
-
- * `manifold-global-types.d.ts`: Defines lower level types and interfaces like {@link manifold.Vec2 | Vec2}, {@link manifold.Mat3 | Mat3}, &c.
- * `manifold-encapsulated-types.d.ts`: Declares objects and types that are implemented in C++, and compiled to WASM.  Definitions of classes like {@link manifold.Manifold | Manifold} and {@link manifold.CrossSection | CrossSection} can be found here.
- * `manifold-root.d.ts`: Defines the {@link manifold.ManifoldToplevel | ManifoldToplevel} interface, and re-exports the above two files.
-
-These three files are consolidated into `manifold.d.ts` using [API Extractor](https://api-extractor.com/).  This is automatically run before each build as an npm lifecycle hook.  It can be run manually as `npm run prebuild`.
-
-### Terminology
-
-These are general guidelines, not hard rules.  The aim of this section is to encourage consistent documentation, not to institute brand standards.
-
-* When referring to the library, manifold should generally be lowercase.  Manifold can be capitalized when grammatically correct, for example at the start of a sentence.  If unclear, `manifold` can be marked up as code to distinguish it from the manifold property.
-* The Manifold class should generally be capitalized.  Where appropriate, it can be linked directly to the {@link manifold.Manifold | Manifold} class documentation.
-* ManifoldCAD should be capitalized.  [ManifoldCAD.org](https://manifoldcad.org) should be a link.

-# Embedding ManifoldCAD
-
-There are three ways to use manifold in your own projects:
-
- 1. Using the ManifoldCAD worker.  The worker adds overhead, but it will sandbox scripts.  It also makes it possible to include packages at runtime.
- 1. Using ManifoldCAD libraries directly.  ManifoldCAD implements importers, exporters, and garbage collection amongst other utilities.  These modules are reasonably light and can be used outside of manifoldCAD.
- 1. Using the [Manifold WASM module directly](./bindings.md) without any of the above.
-
-## Using the ManifoldCAD worker
-
-The worker is a code evaluation sandbox intended to run as a [web worker](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API).  It will bundle a script, include any dependencies, and even fetch those dependencies from a CDN if required.  At run time, it will evaluate the script as a [dynamically created function](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/Function).
-
-See:
-
-  * {@link lib/worker | worker API}
-  * [manifold-cad](https://github.com/elalish/manifold/blob/master/bindings/wasm/bin/manifold-cad) CLI
-
-### Detecting the worker
-
-> [!NOTE]
-> There are slight behaviour differences between scripts running inside the manifoldCAD worker, and those outside.
->
-> See our [import integration tests](https://github.com/elalish/manifold/blob/master/bindings/wasm/test/import.test.ts) for examples.
-
-When evaluated through the worker, {@link manifoldCAD!isManifoldCAD | isManifoldCAD()} will return true.  Otherwise it returns false.

-title: Tips and Tricks
----
-## Handling Precision Issues
-
-> [!WARNING]
-> Geometry where two manifolds are meant to share a face exactly is called **marginal geometry** and should generally be avoided. Manifold uses symbolic perturbation, which means multiple topologically valid results may be within rounding error of each other — so even small imprecisions can produce unexpected output.
-
-Two common sources of trouble:
-
-- **Floating point drift** — JavaScript uses IEEE 754 binary floating point, so `0.1 + 0.2` evaluates to `0.30000000000000004`. Manifold does not compensate for this in its transform pipeline. A bounding box maximum of `0.30000000000000004` instead of `0.3` is enough to prevent a union from closing properly.
-- **Different triangulations** — even with floating-point identical coordinates, if two coplanar faces are triangulated differently, that can also lead to gaps and slivers.
-
-Where marginal geometry is unavoidable, the recommended workaround for floating point drift is to **work in larger, integer-friendly units**:
-
-1. Scale coordinates up by a round factor (e.g., 1000) so your values are whole numbers
-2. Use `Math.round()` after any arithmetic to eliminate accumulated drift
-3. Perform all Manifold operations
-4. Scale the result back down if needed
-
-```js
-const scale = 1000;
-
-// Instead of cube([0.1, 0.1, 0.1]) translated by [0.2, 0.2, 0.2]:
-const size = Math.round(0.1 * scale);   // 100
-const offset = Math.round(0.2 * scale); // 200
-
-const { cube } = Manifold;
-const box = cube([size, size, size]).translate([offset, offset, offset]);
-```
-
-See [discussion #1135](https://github.com/elalish/manifold/discussions/1135) for more context.
-
-## Degrees vs. Radians
-
-Manifold's rotation API takes **degrees**, not radians. This is a deliberate design choice: Manifold can eliminate floating point error entirely for multiples of 90°, and uses more efficient code paths when it detects such rotations.
-
-```js
-// Pass degrees directly
-box.rotate([90, 0, 0]);
-box.rotate([0, 45, 0]);
-```
-
-If your own code works in radians (e.g. when using `Math.atan2`), convert to degrees before passing to Manifold:
-
-```js
-const toDeg = (rad) => rad * (180 / Math.PI);
-
-const angle = Math.atan2(y, x); // radians
-box.rotate([0, 0, toDeg(angle)]);
-```
-
-For common angles, always prefer the exact degree value (`90`, `45`, `30`, etc.) over a computed approximation to get the precision guarantee. See [issue #1262](https://github.com/elalish/manifold/issues/1262) for a real-world example where a rotation of `-89.999999999999` instead of `-90` caused mesh cracks.

-title: Using ManifoldCAD
----
-## Running ManifoldCAD
-
-### With a Browser
-
-Just go to [ManifoldCAD.org](https://manifoldcad.org), and check out the examples!
-
-### On the Command Line
-
-ManifoldCAD has a [command line interface](https://github.com/elalish/manifold/blob/master/bindings/wasm/bin/manifold-cad).  It can be run directly as `./bin/manifold-cad`.  It can also be run via `npx`.  If Manifold is not already present, use `npx manifold-3d manifold-cad` or `npx manifold-3d`.  If Manifold is already installed, `npx manifold-cad` will suffice.
-
-```
-Usage: manifold-cad [options] <infile.js> <outfile>
-```
-
-The output file can be in either `.glb` or `.3mf` format, determined by extension.
-
-## Coordinate Systems
-
-ManifoldCAD uses a right-handed coordinate system where '+Z' is up.  Length units are assumed to be millimetres.  This is slightly at odds with glTF, which also uses a right handed coordinate system, but specifies '+Y' as up, and length units are in metres.
-
-ManifoldCAD will scale and rotate automatically when importing or exporting glTF models.  This means that an arrow pointing in the '+Z' direction in will point in the '+Y' direction after export.  However, that arrow will still point up, and will still be the same size.

+# WASM/JS Examples
+
+This is the home of our editor, [ManifoldCAD.org](https://manifoldcad.org/), as well as our other public examples of integrations with `three.js`, `<model-viewer>`, and `glTF`. Included are `manifold-gltf.js` and `gltf-io.js`, which are intended to be fairly general-purpose libraries for interfacing between manifolds and glTF. We should probably make them into their own npm package at some point.
+
+## Local development
+
+First, follow the directions in the root README to get your C++ build environment set up and working for WASM. From this directory (`bindings/wasm/examples/`) you can test the JS bindings by running:
+
+```
+npm install
+npm test
+```
+
+To develop the manifoldCAD.org editor as well as our other example pages, run
+```
+npm run dev
+```
+which will serve the pages, watch for changes, and automatically rebuild and refresh. This build step doesn't do TS type-checking, so to verify everything is correct (beyond VSCode's TS linting), run
+```
+npm run build
+```
+See `package.json` for other useful scripts.
+
+Note that the `emcmake` command automatically copies your WASM build into `built/`, (here, not just under the `buildWASM` directory) which is then packaged by Vite into `dist/assets/`.
+
+To debug the WASM build directly in Chrome dev tools, simply build in debug mode:
+```
+emcmake cmake -DCMAKE_BUILD_TYPE=Debug .. && emmake make
+```
+and install the [DWARF](goo.gle/wasm-debugging-extension) Chrome extension.
+
+When testing [ManifoldCAD.org](https://manifoldcad.org/) (either locally or the
+deployed version) note that it uses a service worker for faster loading. This
+means you need to open the page twice to see updates (the first time loads the
+old version and caches the new one, the second time loads the new version from
+cache). To see changes on each reload, open Chrome dev tools, go to the
+Application tab and check "update on reload".
+
+### Note for firefox users
+
+To use the manifoldCAD.org editor (`npm run dev`), you'll likely have to set
+`dom.workers.modules.enabled: true` in your `about:config`, as mentioned in the
+discussion of the
+[issue#328](https://github.com/elalish/manifold/issues/328#issuecomment-1473847102)
+of this repository.

-## Local development
-
-First, follow the directions in the root README to get your C++ build environment set up and working for WASM.
-
-To develop the manifoldCAD.org editor as well as our other example pages, run
-```
-npm run dev
-```
-which will serve the pages, watch for changes, and automatically rebuild and refresh. This build step doesn't do TS type-checking, so to verify everything is correct (beyond VSCode's TS linting), run
-```
-npm run build
-```
-See `package.json` for other useful scripts.

-## Manifoldness and EXT_mesh_manifold
-
-<!-- #region summary -->
-<!-- This region will be included in the examples list at https://manifoldcad.org/docs/jsapi/documents/Manifold_Examples.html -->
-
-[ [example](https://manifoldcad.org/make-manifold.html) | [source](https://github.com/elalish/manifold/blob/master/bindings/wasm/examples/make-manifold/) ]
-
-This example will test a glTF model for manifoldness.  Manifold models will be extended with [EXT_mesh_manifold](https://github.com/KhronosGroup/glTF/blob/main/extensions/2.0/Vendor/EXT_mesh_manifold/README.md), a glTF extension for lossless transmission of manifold meshes.  
-
-Our implementation of `EXT_mesh_manifold` is [manifold-gltf](https://manifoldcad.org/jsdocs/modules/manifold-gltf.html), an extension for [glTF Transform](https://gltf-transform.dev).  Although this example uses manifold to test for manifoldness, `manifold-gltf` depends only on glTF Transform.
