Verified usage

Verified import paths — ran on the pinned version, not inferred.

BezierCurve

✓ from bezier import Curve

✗ from bezier import BezierCurve

Class named Curve, not BezierCurve, since v0.9.0

Triangle

✓ from bezier import Triangle

✗ from bezier import Surface

Surface renamed to Triangle in v2020.1.14

intersections

✓ from bezier import intersection_curves_curves

✗ from bezier import intersect

Function renamed to intersection_curves_curves

Create and evaluate a quadratic Bézier curve defined by three control points.

import numpy as np from bezier import Curve nodes = np.asfortranarray([ [0.0, 0.5, 1.0], [0.0, 1.0, 0.0], ]) curve = Curve(nodes, degree=2) print(curve.evaluate(0.5))

Debug

Known issues

breakingSurface class renamed to Triangle in v2020.1.14. Code using `Surface` will break.

fix

Replace `Surface` with `Triangle` in imports and usage.

affects: <2020.1.14

gotchaNodes array must be Fortran-contiguous (column-major). Use `np.asfortranarray` or ensure array is C-contiguous with correct shape.

fix

Always pass nodes as Fortran-contiguous arrays: `nodes = np.asfortranarray(...)`

affects: all

deprecatedPython 3.9 support dropped, requires >=3.10 as of v2024.6.20.

fix

Upgrade Python to 3.10 or later.

affects: >=2024.6.20

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'bezier'

Package not installed or installed in wrong environment.

fix

Run `pip install bezier` in the correct Python environment.

ValueError: nodes must be 2D array (num_axes, num_nodes)

Nodes array not shaped as (num_axes, num_nodes) or not Fortran-contiguous.

fix

Ensure nodes is 2D with shape (dims, points) and convert to Fortran order using `np.asfortranarray(nodes)`.
