This exporter is included and updated as a part of the THREE js project and is no longer maintained in this repository.

collada-exporter-js

Collada / DAE Format exporter for THREE js geometry. The format is described here.

This exporter is included in the THREE.js examples folder here.

Use

var geometry, mesh;
// ...create geometry to export...

var exporter = new THREE.ColladaExporter();

// Form the file content based on the mesh
// and geometry within
var { data, textures } = exporter.parse(mesh);

// save the files!
const zip = new JSZip();
zip.file( 'myCollada.dae', data.data );
data.textures.forEach( tex => zip.file( `${ t.directory }${ tex.name }.${ tex.ext }`, tex.data ) );

ColladaExporter.parse(object, onDone, options)

Converts the provided object tree into a collada file and associated textures. Returns the following object:

{
	// Collada file content
	data: "",

	// List of referenced texures
	textures: [{

		// File directory, name, and extension of the texture data
		directory: "",
		name: "",
		ext: "",

		// The texture data and original texture object
		data: [],
		original: <THREE.Texture>
	}, ...]
}

object

The object to export as a Collada file.

onDone

An optional callback for when the model has completed being processed. The same data is returned from the function.

options

options.version

The Collada file version to export. 1.4.1 and 1.5.0 are the only valid values.

Defaults to 1.4.1.

options.author

The author to include in the header. Excluded if null.

Defaults to null.

options.textureDirectory

The directory relative to the dae file that the textures should be saved to.

Defaults to '', or next to the Collada file.

ColladaArchiveExporter.parse(object, onDone, options)

Writes the processed dae, textures, and manifest.xml file to a zip format to align with the zae Collada format. Requires the ColladaExporter and JSZip.

Limitations

Can only export model geometry, materials, and textures. Animations, skinning, joints, kinematics and other features are not included (issue).
Only phong (default), lambert, and constant material tags are supported.
Only diffuse, specular, and emission maps are supported for export.
Diffuse maps cannot be exported with a tint color (per the spec).
MeshLab has problems importing attributes with shared index offsets (issue).
