B-Splines and Non-uniform Rational B-Splines (NURBS) are a way to represent smooth curves and smoothly curving surfaces with a set of control points. The curve or surface is defined by the control ...

NURBS-diff is a differentiable layer that can be run as a standalone layer for CAD applications like curve fitting, surface fitting, surface offseting, and other applications that rely on Non-uniform ...

Abstract: The main geometric features of the nonuniform rational B-splines (NURBS) curve and surface representations are described. It is shown that most of these features are already exhibited by ...
