	For most shading applications, [[Get Ray Origin]] is the correct function to use when you want to know where the surface is being viewed from. When shading a directly-visible surface (a primary ray), [[Get Ray Origin]] usually gives the same result as [[Get Camera Position]], but if the camera is an orthographic camera you need [[Get Ray Origin]] to find the correct viewer. Even with a regular camera, for realistic reflections and other shading effects (secondary rays) you should account for the actual ray between the point being shaded and the point at which the reflection occurs. These points can be found using [[Get Position]] and [[Get Ray Origin]].
