Hide objects on Click with raycaster

Question

I wanna hide scene objects with clicking on them, I read many "raycaster" tutorials but I don't know where is my fault with these codes when I open my HTML file all the objects are hidden. I have deleted most of irreverent codes to raycaster.

    <script>

        if ( ! Detector.webgl ) Detector.addGetWebGLMessage();

        var SCREEN_WIDTH = window.innerWidth;
        var SCREEN_HEIGHT = window.innerHeight;
        var FLOOR = -250;

        var container, stats;
         var  group1 , group2 , group3 ;
        var camera, scene, controls;
        var renderer;

        var mesh;
        var textureCube;
        var cameraCube, sceneCube;
        var loader;


        var mouseX = 0, mouseY = 0;

        var windowHalfX = window.innerWidth / 2;
        var windowHalfY = window.innerHeight / 2;

        init();
        animate();

        function init() {

            container = document.createElement( 'div' );
            document.body.appendChild( container );

            // CAMERA and controls

            ....

            // SCENE

            scene = new THREE.Scene();

            container.appendChild( stats.domElement );

            // EVENTS

            window.addEventListener( 'resize', onWindowResize, false );
            window.addEventListener( 'mousemove', onDocumentMouseMove, false );


        }

        //

        function onWindowResize( event ) {

            ....
        }


        function onDocumentMouseMove(event) {
            mouseX = ( event.clientX - windowHalfX );
            mouseY = ( event.clientY - windowHalfY );
            mouseVector.x = 2 * (e.clientX / containerWidth) - 1;
            mouseVector.y = 1 - 2 * ( e.clientY / containerHeight );
        }


        //

        function animate() {

            requestAnimationFrame( animate );

            render();
            stats.update();

        }

        function render() {

            controls.update();

            cameraCube.rotation.copy( camera.rotation );

            renderer.clear();
            renderer.render( sceneCube, cameraCube );

        //raycast
             var raycaster = projector.pickingRay( mouseVector.clone(), camera );

            window.addEventListener( 'mousedown', onMouseDown, false );
            var onMouseDown = function ( event ) {
                     var intersects = raycaster.intersectObjects( cubes.children );
                      var intersection = intersects[0] , obj = intersection.object ;
                      obj.visible = false ; 
            };

            renderer.render( scene, camera );

        }

    </script>

You are doing the raycast on every frame while rendering. When you want to raycast on mouse clicks, you need an Event Listener:

window.addEventListener( 'mousedown', onMouseDown, false );
var onMouseDown = function ( event ) {
    var intersects = raycaster.intersectObjects( cubes.children );
    var intersection = intersects[0], obj = intersection.object;
    obj.visible = false ;
};
