The OpenNURBS package has a lot of classes for dealing with NURBS curves
and surfaces, download the Rhino 4.0 SR2 C++ SDK and check out the
functions that are solely part of OpenNURBS. For example, ON_Curve and
ON_Surface are classes dealing with curves and surfaces, and they
already have a lot of functions built-in for manipulation and
evaluation.So you can use it to create and store the NURBS curves and
surfaces in 3DM format, and in case you develop a Rhino plugin, you
would be using the same functions to manipulate those objects. This
library is free to use and redistribute.
But to get solid modelling type of functions with a UI to display
objects, and other more sophisticated algorithms (ie., offset surface),
you need to use Rhino's SDK to build a plugin for Rhino. To answer your
question, Rhino's SDK is free to download and use, but with it you build
a plugin for Rhino and to get the full version of Rhino you have to pay.
But Rhino's evaluation version is free and full featured and allows you
to develop plugins, except that you cannot save the models you create
more than x times.
Hope this helps.
