World Environment
HDR を利用したライティング画像。
The world defines the environment that the scene is in. The surface shader sets the background and environment lighting, either as a fixed color, sky model or HDRI texture. With volume shaders the entire scene can be covered in mist or other volumetric effects.
Surface(サーフェス)

サーフェスシェーダーはその環境からシーンに入射する光について定義します。ワールドのサーフェスはシーンから、オブジェクト間の双方向の作用が存在せずただ光が入ってくるだけと考えられる程、遠く離れた物としてレンダリングされます。シェーダーが受け入れるのは Background ノードにおける Color の入力と光源の強さを表す Strength の値だけです。
Image Based Lighting (イメージベースドライティング)
For image based lighting, use the Environment Texture node rather than the Image Texture node for correct mapping. This supports Equirectangular (also known as latitude/longitude) for environment maps, and Mirror Ball mapping for converting photos of mirror balls to environment maps.
Volume

ボリュームシェーダーはワールド全体、その空間を完全に満たすように適用できます。
Currently this is most useful for night time or other dark scenes, as the world surface shader or sun lights will have no effect if a volume shader is used. This is because the world background is assumed to be infinitely far away, which is accurate enough for the sun for example. However, for modeling effects such as fog or atmospheric scattering, it is not a good assumption that the volume fills the entire space, as most of the distance between the sun and the earth is empty space. For such effects it is be better to create a volume object surrounding the scene. The size of this object will determine how much light is scattered or absorbed.
