[SOLVED] Loading object as Geometry instead of BufferGeometry in threejs

Loading object as Geometry instead of BufferGeometry in threejs

I'm trying to load an .stl file into three.js. Everything works fine and I get the model as BufferGeometry using this code:

    var loader = new THREE.STLLoader();
    loader.addEventListener( 'load', function ( event )
    {

        var material = new THREE.MeshLambertMaterial({
            color: 0x888888,
            side: THREE.DoubleSide
        });

        var bufferGeometry = event.content;
        var mesh = new THREE.Mesh(geometry, material);
        scene.add( mesh );
    });
    loader.load( 'model.stl' );

To make it easier to further manipulate the model I would like to have the geometry as regular THREE.Geometry instead of THREE.BufferGeometry. Is it possible to either load the .stl in a way so I receive it as a THREE.Geometry or is it possible to convert from THREE.BufferGeometry to THREE.Geometry? Or is this possible using a .obj file or sth else?

Solution

This answer only applies to versions of three.js prior to r.125.

STLLoader now returns a BufferGeometry object.

You can convert that to a THREE.Geometry like so:

var geometry = new THREE.Geometry().fromBufferGeometry( bufferGeometry );

three.js r.124
