Question

我是三个人。我正在玩这个样本 http://threejs.org/examples/css3d_periodictable.html

我想知道点击某个特定元素的时间，看到几个样本并添加下面的代码在函数内部设置断点，即使单击元素内部，intersects.length也始终为0。请帮忙！我错过了什么？提前致谢

    function onDocumentMouseDown( event ) {

        event.preventDefault();
        controls.enabled = true;

        mouse.x = ( event.clientX / window.innerWidth ) * 2 - 1;
        mouse.y = - ( event.clientY / window.innerHeight ) * 2 + 1;
        var vector = new THREE.Vector3( mouse.x, mouse.y, 0.5 );
        //var vector = new THREE.Vector3( ( event.clientX / window.innerWidth ) * 2 - 1, - ( event.clientY / window.innerHeight ) * 2 + 1, 0.5 );
        projector.unprojectVector( vector, camera );

        var raycaster = new THREE.Raycaster( camera.position, vector.sub( camera.position ).normalize() );

        var intersects = raycaster.intersectObjects( objects,true );

        if ( intersects.length > 0 ) {

            intersects[ 0 ].object.material.color.setHex( Math.random() * 0xffffff );

            var particle = new THREE.Particle( particleMaterial );
            particle.position = intersects[ 0 ].point;
            particle.scale.x = particle.scale.y = 8;
            scene.add( particle );

        }

    }

Raycaster不适用于css3Drenderer。只需使用元素onclick事件

周期表示例如何查找单击的元素？
