That's not for me to decide, but I doubt that it will happen in the near future. > Of course this would be a nice improvement for any object in the > scenery.

OpenGL and thus PLIB can't handle NURBS themselves. > This idea came into my mind while working with some modeling tools which > let users build complex geometry with simple techniques using nurbs and > I imagine a curved nurbs terrain would be a very high improvement in > visual results :-) For modelling purposes NURBS are great (although they also have drawbacks, but those don't matter here). But to display a NURBS curve/surface it must be tesselated (i.e. converted to polygons/triangles). This process can easily be done - but it takes time. End even more time to get it right (there shouldn't be any edges vissible, it must fit with the rest of the scenery). So that process should happen offline, i.e. at the time the scenery is generated not at the time it's going to be displayed. AFAIK TerraGear already uses NURBS, so there's no problem at all. The limiting factor is IIRC the data format for the airport database - but I remember a discussion that its currently going to be enhanced.
