Those are curves. The world in the '80s belonged to polygons. Somewhere I have a Rhino 0.9 disc from McNeel & Associates. They were the local AutoCAD vendor and had been failing for more than a decade to convince Autodesk that there was a place for non-platonic solids in engineering so they came out with their own. They actually spelled out "Non-Uniform Reticulated Rational B-Spline" on the face. I did finite element analysis in the late '90s. We were still very much integrating by polygons. Deep down in the heart of it all, all your NURBS processing is integration by parts anyway.
