The bigger problem, I suspect, will be main memory (or maybe disk
bandwidth). An impostor scheme is going to be really tile hungry --
constantly dragging tiles off of disk, rendering them into textures,
and forgetting about them.

meantioned earlier, but also makes the framerate quite steady.

Cool glad it works for you
but IMHO what is needed are imposter tiles

This would be really nice for very high flying (X) aircraft.

They should be minimal. For the first tier of imposter tiles, we're
using textures that we already have, and just replacing the tile with

That's a manageable problem. If you think about it, the amount of
impostor texture memory required is exactly that required to draw the
tiles on

Ok, that sounds correct.

Really, we need a routine that works with an arbitrary ssg scene
graph. It's very concievable that someone could import scenery from
some other project with a completely different layout. Also, we are
talking about non-vertical intesection lines when it comes to landing
gear, so a line
Norman,
This does appear to work great! Thanks for tracking this down. I
able to fly successfully both at KBOS and KSFO which I couldn't do
before.
Thanks,
