World Reflection Node
The World Reflection node outputs the reflection result(R) in world coordinates of the camera view vector(V) by the surface normal(N) and is calculated via the following expression R = V - 2 x (V . N) x N.
A reflection based on a per pixel normal map can also be calculated by connecting it to the Normal input port.
This node is commonly used alongside cubemaps to create environment mapping effects.
