The intent is to have another application (which doesn't exist right now) to
scale and orientate the airport properly, output a AC3D file, then match each
vertex in the model to the ground elevation. Then, it should be a simple
matter of placing the airport on top of the terrain. The taxiways may
present Z-buffer problems however, so we need to think this through.
Curt, do you have any idea how we might be able to get these data into FG?
There are a lot of ways we could go with this.
If you could give me a set of polygon outlines for taxiways, I don't
think that would be too hard to integrate with the current airport
generator code. Taxiways are just simple polygons, and the underlying
code can handle arbitrary polygons. There is an issue to think about
with texturing (scaling and orientation) but we can probably do these
free-form taxiways similar to how we do grass? Or maybe we need to come
up with something more sophisticated?
We could also handle the hanger/terminal data in the airport generator
as well I would think. If you could add some sort of height attributte
to each shape, then the airport generator could generate the 3d models
and place them correctly on the airport surface.
The hardest part is generating the data.
Curt.
