Draco3D

Draco3D is a library for compressing and decompressing 3D geometric meshes and point clouds, developed by Google to improve storage and transmission of 3D graphics. The NPM package version 1.5.7 provides Node.js bindings for the Draco encoder and decoder. It supports compression of points, connectivity, texture coordinates, normals, and other generic attributes. Differentiating from raw 3D formats, Draco significantly reduces file sizes while maintaining visual fidelity. The library is released as C++/JavaScript source code, with the NPM package offering pre-built decoders for Node.js and browser usage. Release cadence is stable with periodic updates aligned with the main Draco repository.
