A NURBS library in Common Lisp. It handles both curves and surfaces; it can generate PostScript output for curves and VTK files for surfaces. It also has an own file format (RBN) for storing NURBS data. Features include point / vector operations, curve and surface evaluation, derivation, curvature calculation, algorithms for creating continuity …

CL-NURBS Library

Loading the library should be as simple as:
  (asdf:operate 'asdf:load-op :cl-nurbs)
Or, under SBCL:
  (require :cl-nurbs)

There is no documentation yet, sorry (though most functions should be
self-explanatory).

Any comments, suggestions, patches are welcome.
