2D map issue

[icemagno]

When I change my map to Cesium.SceneMode.SCENE2D the scale bar vanishes....

What is wrong?

I have a solution.

Go to the method function updateDistanceLegendCesium(viewModel, scene) and add this code:

    function updateDistanceLegendCesium(viewModel, scene) {
      var now = getTimestamp();
      if (now < viewModel._lastLegendUpdate + 250) {
        return
      }
      viewModel._lastLegendUpdate = now;
      var width = scene.canvas.clientWidth;
      var height = scene.canvas.clientHeight;
	
// I've changed from here ...  
      var p1 = new Cartesian2(width / 2 | 0, height - 1);
      var p2 = new Cartesian2(1 + width / 2 | 0, height - 1);

      // try to get from a 3D map.	
      var left  = scene.camera.getPickRay( p1 );
      var right = scene.camera.getPickRay( p2 );
      var globe = scene.globe;
      var leftPosition = globe.pick(left, scene);
      var rightPosition = globe.pick(right, scene);
	  
      if (!defined(leftPosition) || !defined(rightPosition)) {
	  // It is a 2D map. globe.pick won't work
          leftPosition = scene.camera.pickEllipsoid(p1, scene.globe.ellipsoid);
          rightPosition = scene.camera.pickEllipsoid(p2, scene.globe.ellipsoid);
	  }
      // ... to here	  
	  
      if (!defined(leftPosition) || !defined(rightPosition)) {
        viewModel.barWidth = undefined;
        viewModel.distanceLabel = undefined;
        return
      }

Now it will work both for 3D and 2D map.
