How to use the sample

How it works

  1. Create a Scene and display it in a SceneQuickView.
  2. Change the atmosphere effect with SceneView.atmosphereEffect.

Relevant API

  • Scene
  • AtmosphereEffect
  • SceneView

Additional Information

There are three atmosphere effect options:

  • None - No atmosphere effect. The sky is rendered black with a starfield consisting of randomly placed white dots.
  • Realistic - Atmosphere effect applied to both the sky and the surface as viewed from above.
  • Horizon only - Atmosphere effect applied to the sky (horizon) only. This is the default.
