Degree and Continuity

 
 
 

The degree of a NURBS determines its continuity or smoothness. In Softimage, NURBS can have one of two degrees:

Like curves, surfaces can be either cubic or linear. In addition, they can have different degrees in their U and V directions, so that they can be smooth in one direction and jagged in the other.

You can convert between cubic and linear by fitting — see Fitting Curves onto Curves and Fitting Surfaces.

In addition to linear and cubic, Softimage supports NURBS of other degrees imported from other programs.
