Highlight SceneLayer

Note: Support for 3D on mobile devices may vary, view the system requirements for more information.

This sample shows how to highlight features in a SceneLayer representing Esri offices. When the SceneLayerView finished updating we loop through all the loaded features and put them in a list. An event listener is added on each list item which zooms to the 3D extent of the feature and highlights it.

To highlight a feature, call the highlight method of the feature's corresponding layerView with the feature or its objectID as parameter.

// add event listener on each list item
li.addEventListener("click", function(evt){
  var target = evt.target;
  // get objectId of the feature that we previously stored as a data attribute
  var objectId = parseInt(target.getAttribute("data-object-id"));
  // create an extent query on the layer view that will return the 3D extent of the feature
  var queryExtent = new Query({
    objectIds: [ objectId ]
  });
  officeLayerView.queryExtent(queryExtent)
    .then(function (result) {
      // zoom to the extent of the feature; we use the expand method as we don't want to zoom very close to it
      view.goTo(result.extent.expand(7), { speedFactor: 0.5 });
    });
  // if any, remove the previous highlights
  if (highlight) {
    highlight.remove();
  }
  // highlight the feature with the returned objectId
  highlight = officeLayerView.highlight([objectId]);
});
