Apply renderers to scene layer

Change the appearance of a 3D object scene layer with different renderers.

Use case

A scene layer of 3D buildings hosted on ArcGIS Online comes with a preset renderer that defines how the buildings are displayed in the application. However, the fill color may sometimes blend into the basemap, making the buildings difficult to distinguish. To enhance visualization, you can apply a custom renderer with a more contrasting fill color, helping the 3D buildings stand out more clearly. Additionally, you can use a unique value renderer to represent different building uses, or a class breaks renderer to visualize building ages - valuable insights for urban planning and analysis.

How to use the sample

Wait for the scene layer to load. The original scene layer displays 3D textured buildings. Tap on the renderer picker and choose a different renderer to change how the buildings are visualized. Each renderer applies different symbology to the scene layer. Setting the renderer to nil will remove any applied symbology, reverting the buildings to their original textured appearance.

How it works

1. Create an ArcGISSceneLayer from a service URL.
2. Add the scene layer to an Scene and display it in a SceneView.
3. Create different renderers:
   • A SimpleRenderer with a MultilayerMeshSymbol and a fill color and edges.
   • A UniqueValueRenderer using a string field and different MultilayerMeshSymbol for each unique value of the building usage.
   • A ClassBreaksRenderer using a numeric field and different MultilayerMeshSymbol for each value range of the year the building was completed.
4. Set the scene layer’s renderer property to the selected renderer.
5. Set the scene layer’s renderer property to nil, resulting in displaying the original texture of the buildings.
