Display Billboards Lat Long and ID on Mouse Over or left_click

I’m tinkering with the code for in the picking example using the the documentation says that position and Id both sets and get the posistion/id but I don’t see how? Also if you do not specify an ID does it automatically assign one.

If we don’t assign an id to a primitive, it will be undefined. If we do assign an id, it will be returned as part of the object returned by Scene.pick.
