Feature Layer Extrusion

This sample demonstrates how to apply extrusion to a renderer on a feature layer.

How it works

To extrude features from a FeatureLayer:

  1. Create a ServiceFeatureTable from an URL.
  2. Create a feature layer from service feature table.
  3. Make sure to set rendering mode to dynamic, statesFeatureLayer.setRenderingMode(RenderingMode.DYNAMIC).
  4. Apply a SimpleRenderer to the feature layer.
  5. Set ExtrusionMode of render, renderer.getSceneProperties().setExtrusionMode(SceneProperties.ExtrusionMode.BASE_HEIGHT).
  6. Set extrusion expression of renderer, renderer.getSceneProperties().setExtrusionExpression("[POP2007]/ 10").
