How it works

  1. Create a scene and display it in a scene view.
  2. Change the atmosphere effect with the SceneView.AtmosphereEffect property.

Relevant API

  • SceneView
  • SceneView.AtmosphereEffect

Additional information

There are three atmosphere effect options:

  • Realistic - A realistic atmosphere effect is applied over the entire surface.
  • Horizon only - Atmosphere effect applied to the sky (horizon) only.
  • None - No atmosphere effect. The sky is rendered black with a starfield consisting of randomly placed white dots.
