Show various kinds of 3D symbols in a scene.
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
Create a GraphicsOverlay
.
Create a SimpleMarkerSceneSymbol
by specifying the size and color.
Create a Graphic
using the symbol and a Point
geometry.
Add the graphics to the graphicsOverlay.
Add the graphicsOverlay to the sceneView.
