Distance composite scene symbol

Change a graphic's symbol based on the camera's proximity to it.

How to use the sample

The sample starts looking at a plane. Zoom out from the plane to see it turn into a cone. Keeping zooming out and it will turn into a point.

How it works

1. Create a GraphicsOverlay object and add it to a SceneView object.
2. Create a DistanceCompositeSceneSymbol object.
3. Create DistanceSymbolRange objects specifying a Symbol and the min and max distance within which the symbol should be visible.
4. Add the ranges to the range collection of the distance composite scene symbol.
5. Create a Graphic object with the distance composite scene symbol at a location and add it to the graphics overlay.
