WorkerScript for heavy canvas3d application

[Wiech_RV]

I have a qt quick application (buttons etc.) for user control and a canvas3d animation in the middle of the screen. However loading the javascript files with JSON.loader for the cad model takes a lot of time and my application freezes for some time. I was trying to run extra thread for the animation with WorkerScript in QML.

The problem is that i cannot give the canvas3d object (QObject) ot the workerscript. Any idea how to solve that problem?

Canvas3D  {
id: canvas3d
anchors.fill: parent
anchors.verticalCenter: parent.verticalCenter
anchors.horizontalCenter: parent.horizontalCenter
focus: true

WorkerScript {
    id: myWorker
    source: 'workerscript.js'
    onMessage: console.log(message.reply)
}
onInitializeGL: {
    //GLCode.init(canvas3d)
    myWorker.sendMessage(canvas3d)
}
WorkerScript.onMessage = function(message)
{  
initScene();
initCamera(message.canvas)
initMeshObjects();
initRenderer(message.canvas);
WorkerScript.sendMessage({'reply': 'WorkerScript done!'});
 }

function initMeshObjects() {
    // ![1]
    var loader1 = new THREE.JSONLoader();

    loader1.load('/rightBack/chrome11.js', function(geometry, materials) {
    var material = new THREE.MeshBasicMaterial({color: 0xCBDAD5,
                                                   ambient: 0x00000000,
                                                   shading: THREE.SmoothShading});
    chrome11 = new THREE.Mesh(geometry, material);
    scene.add(chrome11);
});
}
