Extrude Graphics

Demonstrates how to render graphics extruded in their Z direction.

How it works

To extrude graphics according to a property:

  1. Create a GraphicsOverlay and SimpleRenderer.
  2. Get the renderer's SceneProperties using Renderer.getSceneProperties().
  3. Set the extrusion mode for the renderer with SceneProperties.setExtrusionMode(ExtrusionMode).
    • BASE_HEIGHT, graphic is extruded to various z-values
  4. Specify the attribute name of the graphic that the extrusion mode will use, SceneProperties.setExtrusionExpression("[HEIGHT]").
  5. Set the renderer on the graphics overlay, GraphicsOverlay.setRenderer(Renderer).
  6. Create graphics with their attribute set, Graphic.getAttributes().put("HEIGHT", Z Value).
