HTML3D圣诞树代码让我们可以在网页上呈现出一个3D的圣诞树效果。以下是该代码的实现：

<!DOCTYPE html>
<html>
<head>
  <title>HTML3D圣诞树代码</title>
  <meta charset="UTF-8">
  <style>
    #canvas_container {
      width: 600px;
      height: 400px;
      background-color: #000;
    }
  </style>
</head>
<body>
  <div id="canvas_container"></div>

  <script src="//cdnjs.cloudflare.com/ajax/libs/three.js/r75/three.min.js"></script>
  <script>
    // 初始化场景、相机、渲染器
    var scene = new THREE.Scene();
    var camera = new THREE.PerspectiveCamera(45, 600 / 400, 0.1, 1000);
    var renderer = new THREE.WebGLRenderer();
    renderer.setSize(600, 400);
    renderer.setClearColor(0xffffff, 1);
    document.getElementById("canvas_container").appendChild(renderer.domElement);

    // 添加灯光
    var light = new THREE.PointLight(0xffffff, 1, 100);
    light.position.set(0, 0, 20);
    scene.add(light);

    // 添加圣诞树
    var material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
    var geometry = new THREE.ConeGeometry(4, 8, 4);
    var cone = new THREE.Mesh(geometry, material);
    cone.rotation.x = -Math.PI / 2;
    cone.position.set(0, -4, 0);
    scene.add(cone);

    // 渲染循环
    function render() {
      requestAnimationFrame(render);
      renderer.render(scene, camera);
      cone.rotation.y += 0.01;
    }
    render();
  </script>
</body>
</html>
