Changes the appearance of the atmosphere in a scene.
How to use the sample
Select one of the three available atmosphere effects. The sky will change to display the selected atmosphere effect.
How it works
- Create a
Scene
and display it in aSceneQuickView
. - Change the atmosphere effect with
SceneQuickView::setAtmosphereEffect
.
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.
