Javascript 如何解决这个循环并按顺序呈现圆锥体？

你能帮我解决这个问题吗。这项任务真的一直都很难完成：（

你可以通过一个循环来完成，通过从

j

计算

j

和

k

，而不是再添加两个循环：

var light = new THREE.DirectionalLight(0xffffff, 0.6);
light.position.y = 1;
light.position.x = 1;
light.position.z = 1;
scene.add(light);
light = new THREE.DirectionalLight(0xffffff, 0.6);
light.position.y = -1;
light.position.x = -1;
light.position.z = -1;
scene.add(light);
light = new THREE.DirectionalLight(0xffffff, 0.6);
light.position.y = 1;
light.position.x = 0;
light.position.z = 0;
scene.add(light);
container.appendChild( renderer.domElement );
}
 function animate() 
{   
requestAnimationFrame( animate );
render();   
}
  function render() 
{                           
renderer.render(scene, camera);
}

for（var i=0；i）我们无法解决问题，但我们可能会帮助您解决您面临的问题。您能准备好吗，我们可以玩一下吗？@Engineer，我当然能想到JSfiddle@Engineer，这里是JSFIDLE链接：我希望我的问题得到解决：）@Romier，谢谢你的回复，伙计。我可以像你在上一个问题中帮助的那样使用JSFIDLE链接吗？提前谢谢。我刚刚检查了JSFIDLE的第8个版本，看起来不错。提示：你应该更改
geo.vertices.push（新三点顶点（新三点矢量3（0,0,0））；
by
geo.vertices.push（新三点矢量3（0,0））；
因为
THREE.Vertex
已被弃用（已被
THREE.Vector3
取代）它抛出了一个控制台警报，这会减慢初始加载速度。我已经更新了上面的JSFIDLE：但是现在我想选择单个圆锥体，它后面的子体作为单个选择。例如：如果我在第1层选择圆锥体1并旋转，它在第2层的子体和它在第3层的大子体应该被选择并以ti的速度旋转me。如果我在第2层选择了圆锥体，如果它在第1层上有父对象，它也会被选择，并且它在第3层上的子对象也会被选择旋转。像wise一样，第3层上的圆锥体必须在之前的层上找到它的父对象进行旋转。这些选择取决于JSON。
