NURBS

A C++ library for 2D NURBS curves. The project includes an example program to demonstrate the library's features.

Features

• Define and evaluate NURBS curves of any order
• Manipulate control points, weights and knot vectors
• Evaluate derivatives, tangents, point projections, curve length, curvature etc.
• Control point and knot insertion, knot refinement, curve splitting
• Piecewise linear representation for drawing
• And more 😄

The example program shows how the library can be integrated with Qt, as well as demonstrating most of the library's features interactively.
