Create a NURBS curve, evaluate at a parameter.

from rust_nurbs import NurbsCurve import numpy as np # Define control points (4 points, 3D) control_points = np.array([[0.0, 0.0, 0.0], [1.0, 2.0, 0.0], [3.0, 3.0, 0.0], [4.0, 0.0, 0.0]]) # Create a degree 3 NURBS curve with uniform knot vector and weights curve = NurbsCurve(control_points, degree=3) # Evaluate at parameter u=0.5 point = curve.evaluate(0.5) print(point)

Debug

Known issues

gotchaAll input arrays (control_points, knots, weights) must be of type float (e.g., numpy float64). Integer arrays cause silent type coercion errors.

fix

Ensure control_points etc. are created with dtype=np.float64 or cast via .astype(float).

affects: <=0.28.0

gotchaThe evaluate method expects a single float or array-like of floats. Passing a Python list may work but using numpy array is recommended for performance.

fix

Use np.linspace(0,1,100) for multiple evaluations.

affects: <=0.28.0

gotchaKnot vector must be non-decreasing. If you supply a custom knot vector with duplicate knots at ends, ensure it is strictly non-decreasing. Errors are not descriptive.

fix

Check knot_vector[i+1] >= knot_vector[i]. Use np.sort if needed.

affects: <=0.28.0
