[DGD] using NURBS to generate virtual landscapes

[Shentino]

Beckoning to me from the past, I hear NURBS, used in Rhino to generate 3D
models.

It just occured to me that a super fancy mud might use them to generate
hills and mountains and whatnot.

First, any technical aspects to worry about besides NURBS itself (which I
still have to grok).

Second, does anyone have/has anyone had any experience in this sort of thing
and/or possible insights?

It's still a bit hazy, but I would like to be able to write a geometrically
consistent game, possibly on top of kotaka or phantasmal.  Having NURBS
generate geometry and whatnot would be really cool for modelling landscapes
without the "curse of a million polys"

Geometric consistency would be to satisfy any propeller-headed guys who
would be clever enough to use stuff like triangulation and whatnot to find
treasures, monsters, or fallen allies.
