Hi David,
Well, I think the question was is there any examples of OSG doing that kind of
stuff and I don't recall anything! In fact I've seen one exaple that even
segest the usage of nerbs and only a token segestion of using shaders in OSG!
:x Somthing they need to work on, or so I think!
NURBS are not that useful in real-time 3D for now, graphics cards
concentrate on polygon rendering and OSG focuses this as well. OpenGL
(actually GLU) has some evaluators that allow specifying curves and
surfaces which it will internally tessellate into polygons, but I think
this is not that efficient. If you want such functionality, I think
osgModeling (an external library built on top of OSG) provides it.
As for shaders, I think you haven't looked that hard, there are many
examples in the OSG sources and the examples of using shaders in OSG.
Hope this helps,
J-S
