Examples

These pages walk through basis polynomials, curve derivatives, circular arcs, curvature continuity, surface construction, and point projection onto both curves and surfaces, showing the inputs alongside the printed results and plots they produce. Their complete scripts live in demos/documentation/ and use the NumPy interface (import nurbspy as nrb); the wider demos/ directory also has scripts using the nurbspy.jax interface and a blade parametrization example.
