draco

  • Applies Draco compression using KHR_draco_mesh_compression. Draco compression can reduce the size of triangle geometry.

    This function is a thin wrapper around the KHRDracoMeshCompression extension.

    Example

    import { NodeIO } from '@gltf-transform/core';
import { KHRDracoMeshCompression } from '@gltf-transform/extensions';
import { draco } from '@gltf-transform/functions';
import draco3d from 'draco3dgltf';

const io = new NodeIO()
    .registerExtensions([KHRDracoMeshCompression])
    .registerDependencies({
        'draco3d.encoder': await draco3d.createEncoderModule()
    });

await document.transform(
  draco({method: 'edgebreaker'})
);

await io.write('compressed.glb', document);

    Compression is deferred until generating output with an I/O class.
