Class Sky

java.lang.Object

com.codename1.gpu.shaders.Sky

public final class Sky
extends Object

Sky domes: draw an inside-out sphere (Primitives.sphere(r, 24, 32, true)) around the camera with a Material.Type.UNLIT material and setFogged(false). The colour depends only on the direction from the camera, so the dome's size and position do not matter. The sun follows the scene's light.

For the sky to light the scene as well, give the Environment matching hemisphere colours; ScenePresets does both.
