I think the description should focus on the meaning of the respective term in the lighting equation, and not on a non-technical analogy. In this case, the analogy is a bit misleading on several aspects, including the fact that ambient lighting is not dependent on an area being enclosed. Here's a suggestion: Ambient lights add a constant term to the amount of light reflected by each point on the surface of an object, thereby increasing the brightness of the object uniformly and independently of the orientation of its surfaces. It is often used to represent the base amount of illumination in a scene. ------------- PR: https://git.openjdk.java.net/jfx/pull/717
