Create a uniform B-spline and evaluate at a parameter value.

from splines import UnitBSpline import numpy as np knots = [0, 0, 0, 1, 2, 3, 4, 4, 4] controls = [0, 1, 0, 1, 0] spline = UnitBSpline(knots, controls) print(spline.evaluate(0.5))

Debug

Known issues

gotchaThe `UnitBSpline` class expects a specific knot vector format with repeated knots at the ends for clamped splines. Using a non-clamped knot vector may produce unexpected results.

fix

Ensure knot vector has multiplicity equal to degree+1 at start and end.

affects: all

deprecatedOlder versions used an `evaluate` method that returned a single point; newer versions may return an array. Check documentation for your version.

fix

Update code to handle array output or upgrade to latest version.

affects: <0.3.0

gotchaThe library does not support non-uniform rational B-splines (NURBS) out of the box. Attempting to use weights will cause errors.

fix

Use a different library like `numpy` or `scipy.interpolate` for NURBS.
