Duplication in Scene view classes.

[pixelzoom]

For code review #35.

There's a bit of dupliction in DistanceSceneView, ElevationSceneView, and TemperatureSceneView. You might consider factoring the commonalities out into a NLDSceneView base class.

The bits that they have in common are:

• this.baseView
• some background imagery
• a numberLineNode
• a pointControllerNodeLayer
• Their reset methods are identical.

Or maybe the base class is as simple as this:

class NLDSceneView extends Node {

  /**
   * @param {NLDBaseView} baseView
   */
  constructor( baseView ) {
    super();

    // @private 
    this.baseView = baseView;
    this.addChild( baseView );
  }

  // @public
  reset() {
    this.baseView.accordionBoxOpenedProperty.reset();
  }
}

I made an NLDSceneView as suggested here, but I made the superclass create the NLDBaseView and the DistanceShadedNumberLineNode. I will close this issue, but feel free to reopen if there is more work to be done.

👍🏻 This looks very nice.
