three.js TypeError: Cannot read property 'center' of undefined -

-

i trying import obj (tried different) on server node.js , three.js - got error after parse file. current code how import geometry:

    var loader = new three.objloader();     loader.load(modelpath, function (geometryobj) {     var materialobj = new three.meshbasicmaterial( { vertexcolors: three.facecolors, overdraw: 0.5 } );     mesh = new three.mesh(geometryobj, materialobj);     scene.add(mesh);

here call stack:

this.center.copy( sphere.center ); typeerror: cannot read property 'center' of undefined @ three.sphere.copy (eval @ <anonymous> (/lib/three.js:32:3), <anonymous>:6074:27) @ three.frustum.intersectsobject (eval @ <anonymous> (/lib/three.js:32:3), <anonymous>:6253:11) @ eval (eval @ <anonymous> (/lib/three.js:32:3), <anonymous>:36578:53) @ three.object3d.traversevisible (eval @ <anonymous> (/lib/three.js:32:3), <anonymous>:7943:3) @ three.object3d.traversevisible (eval @ <anonymous> (/lib/three.js:32:3), <anonymous>:7947:23) @ projectscene (eval @ <anonymous> (/lib/three.js:32:3), <anonymous>:36568:9) @ render (eval @ <anonymous> (/lib/three.js:32:3), <anonymous>:35449:28)

i know known issue https://github.com/mrdoob/three.js/pull/3748 , cannot figured out how fix error.

i've got same problem since discovered objects loaded objloader three.mesh instance.

so should :

var loader = new three.objloader(); loader.load(modelpath, function(object) {      // if want add custom material     var materialobj = new three.meshbasicmaterial({         vertexcolors: three.facecolors,         overdraw: 0.5     });     object.traverse(function(child) {         if (child instanceof three.mesh) {             child.material = materialobj;         }     });      // directly add object     scene.add(object); });

also see this question , this example on three.js website.
