How to get the current camera orientation ? about resium

[rot1024]

Hi, you can get a Cesium's viewer object by accessing cesiumElement property of a reference of Viewer component.

For example:

import React from "react";
import { Viewer } from "cesium-react";
import { Math as CesiumMath } from "cesium";

class Example extends React.PureComponent {

  render() {
    return (
      <Viewer ref={e => { this.viewer = e; }}>
        <button onClick={this.inspectCamera}>Inspect camera</button>
      </Viewer>
    );
  }

  inspectCamera = () => {
    const cam = this.viewer.cesiumElement.scene.camera;
    console.log("position", cam.positionCartographic);
    console.log("heading (deg)", CesiumMath.toDegrees(cam.heading));
    console.log("pitch (deg)", CesiumMath.toDegrees(cam.pitch));
    console.log("roll (deg)", CesiumMath.toDegrees(cam.roll));
  }

}

I am working on writing a documentation including some tips such as this!

Thanks a lot. I have just started working on react project which extensively uses cesium. Please let me know if I can help you document any of the features.
(I must tell you, the story book helped a lot in understanding this library)
