Symbols

View on GitHub
Sample viewer app

Show various kinds of 3D symbols in a scene.

Image of scene symbols

Use case

You can programmatically create different types of 3D symbols and add them to a scene at specified locations. You could do this to call attention to the prominence of a location.

How to use the sample

When the scene loads, note the different types of 3D symbols that you can create.

How it works

  1. Create a GraphicsOverlay.
  2. Create various simple marker scene symbols by specifying different styles and colors, and a height, width, depth, and anchor position of each.
  3. Create a new Graphic object for each symbol.
  4. Add the graphics to the graphics overlay with graphicsOverlay.getGraphics().add(graphic).
  5. Add the graphics overlay to the scene view with sceneView.getGraphicsOverlays().add(graphicsOverlay).
