Question

我正在使用Three.js webgl库创建场景。我在第一个场景中有一个纹理。单击此纹理，我试图导航到下一个场景。我编写了一个函数来处理这个场景以移动到下一个场景。单击此纹理，它将按预期移动到第二个场景，但其中没有任何内容可见。所以，我想知道如何以编程方式显示或隐藏场景。这是第一个场景调用第二个场景的代码 “

<script>
  function createsecondScene()
  {

         function setVisibility (scene1, node)
{
    node.visible = scene1.visible;
}

function traverseVisibility (scene1, callback)
{
    var child, i, num_children = scene1.children.length;

    for (i = num_children - 1; i >= 0; i--)
    {
        child = scene1.children[i];
        callback (scene1, child);
        traverseVisibility (child, callback);
    }
}

scene1.visible = false; // or true

traverseVisibility (scene1, setVisibility);

var container, scene2, camera, renderer,  stats, objects=[],length;


projector = new THREE.Projector();
// custom global variables
var familyRoom;

init();
animate();

// FUNCTIONS        
function init() 
{

    // SCENE
    scene2 = new THREE.Scene();
    // CAMERA
    var SCREEN_WIDTH = window.innerWidth, SCREEN_HEIGHT = window.innerHeight;
    var VIEW_ANGLE = 45, ASPECT = SCREEN_WIDTH / SCREEN_HEIGHT, NEAR = 0.1, FAR = 20000;
    camera = new THREE.PerspectiveCamera( VIEW_ANGLE, ASPECT, NEAR, FAR);
    scene2.add(camera);
    camera.position.set(0,-100,450);

    camera.lookAt(scene2.position); 



    // RENDERER
    if ( Detector.webgl )
        renderer = new THREE.WebGLRenderer( {antialias:true} );
    else
        renderer = new THREE.CanvasRenderer(); 
    renderer.setSize(SCREEN_WIDTH, SCREEN_HEIGHT);
    container = document.createElement( 'div' );
    document.body.appendChild( container );
    container.appendChild( renderer.domElement );
    // EVENTS


    // LIGHT
    var light = new THREE.PointLight(0xffffff);
    light.position.set(-100,200,100);
    scene2.add(light);
    // FLOOR


    ////////////
    // CUSTOM //
    ////////////

    // Note: if imported model appears too dark,
    //   add an ambient light in this file
    //   and increase values in model's exported .js file
    //    to e.g. "colorAmbient" : [0.75, 0.75, 0.75]
    var jsonLoader = new THREE.JSONLoader();
    jsonLoader.load( "LivingAndOtherRooms/RoomModel.js", addModelToScene );
    // addModelToScene function is called back after model has loaded

    var ambientLight = new THREE.AmbientLight(0x111111);
    scene2.add(ambientLight);



}

function addModelToScene( geometry, materials ) 
{
    var material = new THREE.MeshFaceMaterial( materials );
    familyRoom = new THREE.Mesh( geometry, material );
    familyRoom.scale.set(35,10,3);
    scene2.add( familyRoom );


}

function animate() 
{
    requestAnimationFrame( animate );
    render();       

}



function render() 
{
    renderer.render( scene2, camera );
}


}
