Mesh optimization library that makes meshes smaller and faster to render
npm install meshoptimizerThis folder contains JavaScript/WebAssembly modules that can be used to access parts of functionality of meshoptimizer library. While normally these would be used internally by glTF loaders, processors and other Web optimization tools, they can also be used directly if needed. The modules are available as an NPM package but can also be redistributed individually on a file-by-file basis.
When using the NPM package, package exports can be used to import individual components (e.g. meshoptimizer/decoder) as well as the entire package (meshoptimizer).
Each component comes in a separate file, meshopt_component.js, which uses ES6 module exports and can be imported from another ES6 module. The export name is MeshoptComponent and is an object that has two fields:
- supported is a boolean that can be checked to see if the component is supported by the current execution environment; it will generally be false when WebAssembly is not supported or enabled. To use these components on browsers without WebAssembly a polyfill library is recommended.
- ready is a Promise that is resolved when WebAssembly compilation and initialization finishes; any functions are unsafe to call before that happens.
In addition to that, each component exposes a set of specific functions documented below.
MeshoptDecoder (meshopt_decoder.mjs) implements high performance decompression of attribute and index buffers encoded using meshopt compression. This can be used to decompress glTF buffers encoded with EXT_meshopt_compression extension or for custom geometry compression pipelines. The module contains two implementations, scalar and SIMD, with the best performing implementation selected automatically. When SIMD is available, the decoders run at 1-3 GB/s on modern desktop computers.
> Note: for maximum compatibility, MeshoptDecoder is also available as CommonJS module via meshopt_decoder.cjs; it can be used by a wide variety of JavaScript module loaders, including node.js require(), AMD, Common.JS, and can also be loaded into the web page directly via a
