I've just wrapped up an app that uses GTS so I'll throw in my two cents. It's better than DelaunayTriangulator, but it's still very limited in its support of constraint edges. I ended up taking a hybrid approach I won't go into here. GTS is a better triangulator, though, so it might be worth wrapping. One problem is that it's very old school objected oriented C, which may not mesh well with OSG. Or my brain for that matter.
