I think the key aspects of an Ambient light are that: the light seems to come from all directions (and thus has no position or direction), and that it illuminates objects independently of the position or orientation of the object. I don't have a problem with also giving a real-world analogy if one can be found that makes it easier to understand without causing confusion. ------------- PR: https://git.openjdk.java.net/jfx/pull/717
