public class SkySphere
extends BackgroundRenderPass

A sky box is background node intended to display the sky with a far away appearance but without consuming massive computational resources. It is drawn with the depth buffer disabled, so all objects which are drawn after it will be drawn in front. Even though it respects View's angle, it will always be drawn as if the View (camera) were in its center regardless of the actual position.

This implementation creates a sphere to provide a more realistic sky than SkyBox. The downside to using a sphere is that you need a panoramic picture to use as the Texture. This implementation also uses GeoSphere geometry so that it doesn't create a ridiculous number of triangles.

This class ignores the default setting for pickable and sets itself to NOT pickable. You must explicitly call setPickable( true ) on SkyGeoSphere nodes regardless of the default setting.

Originally inspired by William Denniss's SkyBox.
