The Sampler Info node is a color image that provides information about the scene, with the choice to show any of various aspects as color blocks. This provides information about various aspects of the shaded points such as position, normal, bump normal, reflection/refraction vectors and UVW coordinates. It can be used either for world position passes or normal passes. It also extracts information about the scene, converting the gathered information into RGB data for use in compositing.
