# 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/`](https://github.com/turbo-sim/nurbspy/tree/main/demos/documentation)
and use the NumPy interface (`import nurbspy as nrb`); the wider
[`demos/`](https://github.com/turbo-sim/nurbspy/tree/main/demos)
directory also has scripts using the `nurbspy.jax` interface and a
blade parametrization example.
