A C++ Library for NURBS Basic Algorithm, refer the NURBS Book

Introduction

LNLib is a C++ NURBS Basic Algorithm Library.
These algorithms are primary referenced from The NURBS Book 2nd Edition.
The APIs are re-designed to make it more friendly to users.

Features

Basic Elements:

• UV
• XYZ
• XYZW
• Matrix4d

NURBS Algorithms:

• Basis Function Computation
• Bezier/B-Spline/NURBS Curve and Surface
• Curve and Surface Decomposition
• Knot Insertion and Removal
• Knot Refinement
• Degree Elevation and Reduction
• Point and Tangent Inversion
• Curve and Surface Reverse
• Curve Transform
• Create Arc and Conic Curve
• Create Bilinear/Cylindrical/Ruled/Revolved Surface
• Global/Local Curve/Surface Interpolation & Approximation

This library is under development.

Roadmap

• Algorithms of Chapter 10 & 11 in The NURBS Book 2nd Edition
• Other Common NURBS algorithms
