## Example

```js
import React, { Component } from 'react';

import * as THREE from 'three';
import ReactDOM from 'react-dom';

var TransformControls = require('../controls/TransformControls')(THREE);

export default class Example extends Component {
  constructor(props, context) {
    super(props, context);

    this.cameraPosition = new THREE.Vector3(0, 0, 5);

    this.state = {
      cubeRotation: new THREE.Euler(),
    };

    this._onAnimate = () => {
      // we will get this callback every frame
    };
  }


  componentDidMount() {

    var material = new THREE.MeshBasicMaterial({
      color: "#1300FF",
      transparent: true,
      depthWrite: false
    });

    var object = new THREE.Object3D();
    var plane = new THREE.Mesh(new THREE.PlaneGeometry(25, 5), material);
    var control = new TransformControls(this.refs.camera, ReactDOM.findDOMNode(this.refs.react3));
    //control.addEventListener('change', render);
    control.attach( plane);
    object.add(control);
    object.add(plane);
    

    this.refs.group.add(object);
  }
