Well, I think you need both things...you need a high level format that is powerful enough to generate what you want and _if_ you don't do 100% of the compilation in the sim, you need a container format for the results that is adequately expressive and efficient. I am proposing the second but not the first, and if you do not need such a container format, well, it's nto very useful. :-) > But scenery generation actually is not the whole story.

I don't think that we've removed any of the existing high level info from 850 that would have been useful, we just haven't brought the level up.

Shouldn't the meaning of the cited > text be "The following _columns ...." ? This appears to be a zero-meters-long runway. :-) I think this is simply a bad example in Robin's spec. The lat/lon pairs for the runway ends really should (must?) be different. Those two points should be the intersection of the extended runway centerline with the threshhold (not displaced threshhold) of the runway. > I'm not trying to torpedo your work on the new schema, I'm simply > trying to understand it _before_ I point my gun at you ;-) It's a good question - I'll try to answer any q's I can. The docs are still in a pretty raw state - Robin only did the first spec on Friday! *Cheers* Ben -- Scenery Home Page: http://scenery.x-plane.com/ Scenery blog: http://xplanescenery.blogspot.com/ Plugin SDK: http://www.xsquawkbox.net/xpsdk/ Scenery mailing list: [EMAIL PROTECTED] Developer mailing list: [EMAIL PROTECTED] _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
