Yeah... to be discussed. I don't know much about trees, except that they are nodes made out of a couple of vertices (I think Stuat can correct me on this). But you're right about the buildings and radar alt. I suggest changing the signature of FGScenery::get_elevation_m to include a flag: surface only, and set the traversal mask accordingly. I will do just that today and report the results. I want this to be retro- compatible and no changes to other code that relies on get_elevation_m. Like I mentioned last night, not having to traverse all the random buildings, trees and whatnot speeds the intersect visitor result quite a lot, if only terrain elevation is desired. Any comments?
