ArcGIS Runtime SDK for Java

Elevation Mode

Demonstrates how to position graphics using different elevation modes.

How it works

To position Graphics using SurfacePlacement (DRAPED, RELATIVE, ABSOLUTE):

  1. Create a GraphicsOverlay.
  2. Set the surface placement mode GraphicsOverlay.getSceneProperties().setSurfacePlacement(SurfacePlacement).
    • Draped, Z value of graphic has no affect and graphic is attached to surface
    • Absolute, position graphic using only it's Z value
    • Relative, position graphic using it's Z value plus the elevation of the surface
  3. Add graphics to the graphics overlay, GraphicsOverlay.getGraphics.add(Graphic).
  4. Add the graphics overlay to the SceneView, SceneView.getGraphicsOverlays().add(GraphicsOverlay).
