Symbols

Demonstrates how to create symbols with different 3D shapes. Includes tetrahedrons, cubes, spheres, diamonds, cylinders, and cones.

How it works

To create a SimpleMarkerSceneSymbol with a 3D shape:

  1. Create a GraphicsOverlay.
  2. Create a SimpleMarkerSceneSymbol(Style, color, width, height, depth, AnchorPosition).
    • You can also use SimpleMarkerSceneSymbol.createCone(color, diameter, height)
    • color, hex code color of symbol (Red = 0xFFFF0000)
    • (width, height, depth), size of the symbol
    • AnchorPosition, where to postion symbol on Graphic
  3. Create a graphic using the symbol, Graphic(Geometry, Symbol).
  4. Add the graphic to the graphics overlay, GraphicsOverlay.getGraphics().add(Graphic).
  5. Add the graphics overlay to the SceneView, SceneView.getGraphicsOverlays().add(GraphicsOverlay).
