.vertices array does not give the vertices in THREE.js

问题

I am using OBJloader to load an .obj file in WEBGL , Three.js. I want to access the vertices and faces of the objects but the geometry.vertices does not return the vertices positions and it gives me undefined.

Here is a piece of code:

 var tool= new THREE.OBJLoader();
 tool.load( '../obj/tool.obj', function ( object ) {
            var material = new THREE.MeshLambertMaterial({color:0xA0A0A0});             
            object.traverse( function ( child ) {
                if ( child instanceof THREE.Mesh ) {
                   child.material = material;
                   console.log( "child" + child.geometry.vertices);} }

I am thankful for your helps in advance.

If the loader you are using is returning BufferGeometry, you can convert the returned geometry to Geometry in the loader callback using a pattern like so:

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