wanted: info on NURBS-based geometry library

[zyda res acct]

I am interested in a NURBS-based geometry library to use within
engineering and manufacturing applicatons. I would like info about
geometry packages for the development of curve, surface and solid
modeling applications on a IRIS 4D using points from a 3D laser
digitizer as input. I know that the gl supports NURBS but would like
to know if anyone has info on other libraries available. Specifically,
those that have been used with digitized data sets. Thanks!
